Hello !
This might sound like a simple question to all Siemens Gurus... I want to execute some "bench test" with an S7-314 PLC. I have attached an Analog Input Module and an Analog Output module to the PLC. I have carefully set the measuring range cards on the leftside of the AI module, and I have placed them correctly on the rail with their extension connectors.
I have correctly setup the hardware configuration on Step7.
Problem is: Everytime I power the PLC up, both analog Input and Output modules' LEDs become red. I wonder If they are doing so because I have not attached the frontal 20-poles connectors to them, but in the other modules I have installed so far show no errors (Digital Inputs and outputs from the CPU).
Is it a requirement to attach and wire the frontal connectors so that you can carry on with testing your software before connecting the real signals from the field?
References for the AI: 6ES7 331-7KF02-0AB0 and AO: 6ES7 332-5HD01-0AB0. I have not been able to find a Documentation with troubleshooting guide for the AI/AO setup.
Please help. Thank you very much.
