Hi everyone,
I am new to PLC. Inneed to connect, flow meter withcommunication module rs485andPT100 thermal sensors toS7-1200. Kindly helpme on choosing the appropriatesignal boards for these devices. Finally,what is a signal module? thanks in advance.
Welcome to PLC programming! Here's guidance on selecting signal modules for your S7-1200 application:
For your devices, consider the following:
A signal module acts as an interface between field devices (like flow meters and sensors) and the PLC. It converts signals from these devices (e.g., 4-20mA, RS485, resistance) into a format the PLC can understand, and vice versa. They handle signal conditioning, isolation, and conversion.
For further assistance and to explore the full range of signal modules, please visit the S7-1200 Product Page or SiePortal for detailed configuration information.
