Hello,

The module is based on 6ES7134-4GD00-0AB0

Here is a link to manual: SIMATIC ET 200S distributed I/O 4AI I 2WIRE ST analog electronic module (6ES7134-4GD00-0AB0) 

See paragraph 1.1 for wire connection.

It is a 2-wire card, that means you have a Passive sensor? The card supplies the power to generate the mA.

Or do you have an Active sensor, the supply of the sensor is from another powersupply, Then you need a 4-wire card.  (6ES7134-4GB11-0AB0, see manual 2AI I 4WIRE ST analog electronic module (6ES7134-4GB11-0AB0)  

(See paragraph 1.1 for wire connection)

Hi,

What have you tried so far?

Did you use another channel?

Are all channels used? 

What diagnose is there on the card? Any leds are on?

(How did you measure 14mA?

Best regards,

Hi,

Planning on stopping the plant as hardware chabges reguire stopping the CPU. Install additional 5 AI modules. On first one turn on all diagnostics, connect different sensors to all channels. The thing is I am not sure about power supply requirements. There is an new Power module installed right befor AI module, searching would it be enough for 6 AI modules

 Hi,

Should be possible, an analog input module does not need much current. To be sure have a look at the technical description of Analog input card.

Hello,

Could you give some information about the Analog input module?

What addresses are configured?

How do you read the analog input channel 0?

Are you using TIA Portal or Simatic Manager software?

Hello,

Did you change the Process Image?

Otherwise, you need to read PIW256 (for example move PIW256 to MW256)

Or change your addresses of your Card to IW100 for example. (Below 128)

Hi,

The CPU reads every cycle the Process Image. And put it in a table, to be used in the program.

Go to properties of CPU151-8, -> Cycle

Here you will find the Size of Process Image Input and output. Those addresses are read every cycle.

But when your address is outside this Process Image, you will need to read it through PIW, it will go to your card and get the value of the address.

Perhaps this link might help:Where and when do you need peripheral addressing?

This is for S7-300/ S7-400 CPU's
