Hi, Please look for the handbook of the MTA modules... instead of the TPA modules of Top Connect. Marshalled Termination Assemblies ET 200M Remote I/O Modules If you already have the TPA modules, then please look in the handbook S7-400Hof the H-System in chapter F Connection examples for redundant I/Os. |
I hope that the answer will help, if you have still questions, don't hesitate to ask me. |

Supposing you are talking about the 6ES7331 7NF00-0AB0. Left side has several 250 Ohm resistance. They are there to use it with the current sensors. When the current goes from pin 2 to pin 3 (for example), a voltage is generated between this pins due to the 250 Ohms. If you calculate, 4 mA generate a 1V voltage, and 20 mA generate a 5V voltage. This voltage has to be wired to the 22 and 23 pins (in this case) where the op-amps of the right side can translate the voltage given depending of the configuration given in the HW-Config. Please note that I'm always refering to the pins of the module I hope this has been helpful for you You can find more information of the analog input modules in the following address. https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&lang=es&siteid=csius&aktprim=0&extranet=standard&viewreg=WW&objid=10805159&treeLang=es Best regards |
