Hey everybody, Sean Tierney here from theautomationschool .com.

And in this episode of the automation show, We're going to take a look at the S7 -1200 Expansion I /O modules which are known as signal modules.

And the good folks over at Siemens sent me in a larger S7 -1200 with several modules.

And we'll just take a look at them quickly here.

The ones I have set up today are a digital input expansion module, a digital output expansion module, and then an analog in and out expansion module.

And you can see right there, the first one's an SM -1221.

The next one is an SM 1234.

Now what I've done is I've wired a bunch of stuff I had lying around the office here to these

and let me just zoom out some and show you what we got here.

So this guy down move some of this other stuff in.

So what I've done is I've started with the IFM temperature sensors

that we used in the last episode because I already had them out and And they output both discrete and analog, right?

So that gives me my inputs to the system.

So I'll have some discrete inputs here.

You can see right in there, I got two discrete inputs coming in, one from each temperature sensor.

Okay.

And then I have my analog in right here.

So here's my two analogs from those two sensors.

Now I've wired one as current and one as voltage.

And that's why you see I'm actually skipping input number one.

zero and number two because as we'll see input zero one have to be the same type

so current or voltage so um Those are my inputs now for my outputs digital outputs.

I just wired in a couple of

leftover LED pilot lights from one of my courses as well as the meters I use on When I'm teaching analog, you know, getting started with analog modules.

So I have, you know, 0 to 10 and 4 to 20 meters right here.

So we'll be using these two right here.

So those are wired.

You can see right here on the analog output.

You can see I have the first one, output number 0, wired as current.

And the second one is wired as voltage.

The wiring here looks identical, right?

But these meters are actually different inside.

setup here again empowering everything with the side top power supply

which is great because it has you know over current protection short circuit protection and all of that so um

Before we turn this all on, let's see if we can't convert our program from our last S7 -1200

project and see if we can convert it to this new controller

and add these I /O modules and configure them correctly so this all works.

So with that set up, before we go over the computer though, I do want to thank all our patrons over at patreon .com /automation.

And now we can go over to the computer.

so here we are this is the program i actually just

renamed it here let me hide vmware i actually renamed it to project

03 underscore v16 the last one we did was 02

and the first thing i want to do i'm going to go to devices

and networks i'm going to double click on the device here

and i need to change this because this is a 1214

and that's not what i have here as a matter of fact let's zoom in on the controller

if you remember last time we did this we had a 1212c

so i'm going to go ahead and change this controller change device Okay, we want a 1214.

Okay, there it is.

Now notice it's choosing version 4 .4 firmware.

this is going to cause us a problem because That's not 4 .4 firmware.

So in any case, we will see what happens when we try to download it, what happens and the errors we get.

So let me go ahead and click on OK.

Okay, saying, hey, I'm going to close your Obi -Wan.

OK, here we are.

Now look, all the extra signal modules I can add to this unit because it's a bigger unit, so it has more expansion capability.

So now the first thing I want to do is let me add the digital input.

This is an eight point input.

And let me make this bigger here.

And let's make this bigger too.

Okay.

So let's go ahead and drop this in here.

Okay, you can see the 1221 right there.

Okay, next we have a digital output.

Thank you.

It's an 8 point.

Drop this guy right over here.

Okay, you can see it's a 1222 and last

but not least I have an analog in out and So let's go look for the Thank you.

Analog in and out.

and I'll drop this one And here, you see?

1234. Okay, so far so good.

Now, the next thing I'm going to want to do is I'm going to want to set up the analog.

So channel zero...

I'm going to have set for current.

OK?

Now channel 1, you'll notice I can't change it.

That's what I was telling you earlier.

I had to wire the voltage to channel 2 so that I could

uh choose it differently because whatever i set this to is what the next channel will be Set to.

And again, you can see plus or minus 10 volts.

There is no zero to 10 volt selection here.

Okay, so with that done, let's look at the outputs.

I want the first one to be current.

Thank you.

And the second one to be voltage.

Okay, so now that I've set up my analog, it's not really anything set up to do with the digital.

Well, except I could create some tags.

Let's go ahead and create some IO tags here.

So we're going to be using the first two inputs.

So I'm going to call this DI.

underscore and this is slot two so I'm going to call it 20 Whoops.

Twenty?

Now this is my own nomenclature.

These are my own tags.

I'll call the next one 21.

You can name your tags whatever you want.

Typically your company will have a standard that you're going to go by or, you know, um, a format that you're going to use you know so in any case let's do the outputs now so i'll do

do underscore this is slot three so i'm just going to go to three zero and This is what works for me.

100

D -O, whoops, D -O, 31.

101

Okay, now let's go to the analog.

102

Okay. So, IoTags, analog ends.

103

I'm going to call this AI _I _I _I _I _I

104

_I _I _I _I _I _I _I _I _I _I _I

105

_I _I _I _I _I _I _I _I _I _I _I _I _I _I _I _I _I _ Let's see here.

106

It's slot four, so I'll call it four.

107

Whoops.

108

4 -0.

109

And I'll call this one, I'm not using it, but I'm just going to go and order here for one.

110

Thank you.

111

and then this is the other one I'll be using AI _42 That should be good enough for a quick little program.

112

Alright, well speaking of program, let's open up Obi -Wan.

113

our main program here.

114

And let me make this smaller.

115

And you know what I want to do is, when one of my inputs comes on, I want to turn the corresponding output on.

116

So in other words, if sensor one is out of range, I want to turn on light one.

117

And if sensor zero is out of range, I want to turn on light zero.

118

Okay, so I just happen to have red and green, but we'll just, we'll just use those as indicators that the corresponding sensor is on.

119

So let me come in here.

120

and we'll drop this right here and now let's go grab one of these uh outputs here and put it right there.

121

So And I will do the same thing again.

122

Contact and coil.

123

Excellent.

124

So this input will be our digital N20, and we'll go to digital out 30.

125

And this one will be digital in...

126

21 I'll go with digital output.

127

31 and again as you know i'm new to semen so

128

if there's any experts out there who have some tips and tricks Please share them with us.

129

We would love to know about them.

130

The next thing I want to do is I want to take the analog, right?

131

I want to take those analog values coming in

132

and throw them to the output so I can see them on the meters. So let's go ahead.

133

And I think in this case, I'm going to use a move.

134

Yeah.

135

Okay.

136

This is what I would do in other controllers, so I'm just going to do it here.

137

I don't know if this is the best way to do it, but it definitely seems to work.

138

So I'll take an analog input 0.

139

Now wait a minute, that's not what I want.

140

I want, you know, that's from the old program.

141

I want analog input 40, and I'm going to put that out to analog output.

142

Where's my analog output?

143

Hmm.

144

Did I forget to do that?

145

Let's go back there.

146

Thank you.

147

All right.

148

Okay.

149

Thank you.

150

Thank you.

151

Uh -oh.

152

Thank you.

153

Let's see.

154

yeah i did look at that so a o we'll do 40.

155

Thank you. and 8041.

156

Okay, so let's go back to our code and We're going to say Thank you.

157

ai40 goes to AO 40.

158

Okay, and we'll put another move over here. And we'll take...

159

A I 42.

160

Remember, we're skipping 41 because it has to be the same as 40, and I wanted to try both current and voltage.

161

And we're going to take this out to A O 41.

162

Okay, so everything's looking good, right?

163

Well, I don't think we're going to be able to download it because I think there's a problem with the firmware.

164

It doesn't match.

165

This, I think, is newer firmware.

166

what I did, the 4 .4, and that doesn't have that firmware in there.

167

So, well, let's try it.

168

We'll see what happens.

169

So I'm going to select the processor.

170

I'm going to click on Download.

171

Of course, I will have to turn...

172

power on.

173

So let me do that and I'll be right back.

174

Okay, everything's plugged in and powering up.

175

So in a moment we should be good to go.

176

Excellent.

177

All right.

178

So now let's start a search.

179

Thank you.

180

Okay, there it is.

181

It found it.

182

my 1214 C now originally it had once 192 1680 .10

183

as the address in the pre -show I actually download

184

and test it make sure everything worked

185

so now it has the same address as my other s7 1200 has of course

186

because I just converted the same program so let's go ahead and load it in Okay, look at it.

187

failed.

188

Fail will happen.

189

Thank you.

190

Not a compatible firmware rev!

191

Wow.

192

So we were right.

193

You can see the error here as well.

194

So how are we going to fix this?

195

Well, what I'm going to do here is I'm just going to go back into the controller.

196

Change the...

197

Change device.

198

I'm going to make it firmware, let's make it the oldest one possible.

199

Thank you.

200

Okay, so we want to change it to...

201

Hey.

202

Let's make it...

203

4 .0.

204

Okay, we're going to see what will happen if I do that conversion, but that's okay.

205

Okay, it's going to close and reopen the Obi -Wan.

206

That's fine.

207

Okay, now let's try to download it.

208

Okay, we'll load it. And finish.

209

Okay.

210

And let's pull up our...

211

PLC tags.

212

We'll monitor those.

213

Okay, great.

214

Now we can see here on the analog inputs, ten thousand And...

215

6000 roughly right And the analog outputs, 10 ,000, 6 ,000, because I'm just copying that.

216

Here, let's pull open the OB1.

217

We'll take a look at that.

218

And let's monitor this guy.

219

You can see I'm taking whatever comes in.

220

I'm putting it right back out.

221

So let's go back to our tags here.

222

And we can also see...

223

If we look through here, Both of these are on.

224

the dl20 and 21 are both on because i'm below my range

225

so i should be able to do two things here let's go back to obi -wan And we'll scroll up here.

226

Okay, you can see both my lights are on.

227

Okay, and what I'm going to do is, you can see I really got the temperature down in here this morning.

228

okay now you can see that going they were like at 64.

229

so now they're climbing climbing climbing

230

oops this one went to 80 that one's still at 78 so you can see i got one output and um

231

if i bring the other one over 80.

232

I get the other output.

233

Oh, this one already dropped down below 80.

234

Okay, so I'll warm them up quite a bit over 80.

235

And I got both my outputs.

236

We can come back here and we can see the code here.

237

See that's working.

238

Now one of the other things too is we can watch.

239

We'll actually see our outputs are changing on the meters.

240

Our output's changing because...

241

these values are changing.

242

So let me let me go ahead and do this what I'll do is I'm gonna I

243

uh turn the air conditioning on try to cool these sensors off really quick

244

and then we'll come back and you'll see

245

that these meters have changed dramatically matter of fact before i do that i'm

246

Let me go ahead and zoom in on them.

247

And we'll watch them change as they cool down, these bottom two.

248

Thank you.

249

Thank you.

250

Okay, I actually put the temperature sensors right in the grill of the air conditioner

251

and they're down in like 47 and 49.

252

are their temperature.

253

So what I'm going to do here, I'm going to stop the air conditioner because it's kind of loud.

254

I'm going to go grab the units here.

255

Keep your eye.

256

on the meters because I'm going to grab them

257

And you should see the meters go up because I am holding on to them.

258

Using my body heat, to raise their values Yeah.

259

and i should get them all the way through yeah let's see if i can get them under the camera here

260

Get them all the way through.

261

The 65 to 80 range.

262

and all the way up into the 80 + range.

263

when their outputs will come on, Yep, see that?

264

You can see the meter is changing too because we're taking that analog in.

265

One of these is current, one is voltage, and we're putting it to the analog outputs.

266

Okay, and we can see that on the screen as well in our code.

267

So with that, that's how easy it is to use signal modules with the S7 1200.

268

You just add them into your project.

269

Um, download you know configure analog of course just download and go so it's really very simple to do

270

and um yeah that's it

271

so i wanted to say a huge thank you to siemens

272

for saying i'm in i can't wait to do more with them we even have more modules to look at

273

but if you're looking at expanding your 7 1200 with some additional signal modules

274

yeah it can't get much easier than that right so with

275

that i just want to thank you for watching for subscribing please give us a like

276

if you enjoyed the show i also want to thank all

277

of our patrons over at patreon .com forward slash automation um you guys really uh you can help us

278

and keep us going and i also always love to throw out

279

that if you know anybody looking for automation training check out my website theautomationschool .com And, uh, Let them know that I sent you here from the automation show.

280

And with that, I want to wish you all of every safe, healthy and happy week and until next time my friends Peace.

Por que praticar a fala com este vídeo?

Praticar a fala em inglês é essencial para o desenvolvimento da fluência e confiança. Neste vídeo, Sean Tierney apresenta uma demonstração prática sobre os módulos de sinal da Siemens S7-1200. Através de um contexto real, os espectadores são expostos a um vocabulário técnico e a uma estrutura de fala que é comum em ambientes de engenharia e automação. Essa imersão ajuda a melhorar a pronúncia em inglês e a compreensão auditiva, oferecendo uma oportunidade única para treinar o shadowing em inglês. Ao repetir as falas enquanto ouve o vídeo, você pode aperfeiçoar sua entonação e ritmo, elementos cruciais para a comunicação eficaz.

Gramática & Expressões em Contexto

No vídeo, algumas estruturas gramaticais e expressões se destacam. Aqui estão três exemplos a serem observados:

Estrutura de perguntas: “Can we convert our program...?” Esta forma pode ser utilizada para fazer perguntas sobre a possibilidade de ações, sendo útil em conversas técnicas.
Uso do presente contínuo: “We are going to take a look...” Essa construção é comum para descrever planos ou ações futuras, ajudando a trazer uma sensação de imediata realização.
Palavras de ligação: A expressão “as a matter of fact” é um exemplo de como conectar ideias de forma fluida, essencial para manter um diálogo coerente.

Compreender e praticar essas estruturas pode enriquecer seu vocabulário técnico e melhorar sua capacidade de se expressar em inglês.

Armadilhas Comuns de Pronúncia

Embora o conteúdo técnico seja informativo, algumas palavras podem ser desafiadoras para aprendizes de inglês. Estas são algumas das palavras e frases que podem causar dificuldade:

"automation": A pronúncia pode ser confusa. Tente dividir em sílabas: au-to-ma-tion.
"discrete": Muitas vezes pronunciada de forma incorreta; preste atenção no som final "te".
“configuration”: Uma palavra longa que requer atenção ao sílaba tônica, para evitar confusão na fala.

Utilizando o shadowing site para praticar essas palavras, você pode aperfeiçoar sua capacidade de falar com clareza. Assim, além de entender o conteúdo técnico, você também melhora a pronúncia e a fluência ao se expressar.

Gramática neste vídeo

As estruturas que o falante mais usa, com as palavras exatas do vídeo:

Estrutura	No vídeo
Present perfect have/has + particípio passado — uma ação passada que ainda importa agora	have set · I've done · I've wired
Voz passiva be + particípio passado — o foco está no que acontece, não em quem faz	are known · are wired · is wired

O que é a Técnica de Shadowing?

Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
