Hi! I have an automation project that requires a large number of sensors (up to 30). All sensors have analog outputs (0-10 V), and I pretend to use an S7-1200 CPU 1215C PLC. My first option consists of using AI modules (https://support.industry.siemens.com/cs/products/6es7231-5pf30-0xb0/s7-1200-analog-input-sm-1231-rtd-8-ai?pid=124479&mlfb=6ES7231-5PF30-0XB0&mfn=ps&lc=en-DE). However, I found this option to be expensive, as I need 4 of those modules. I also did some research on serial communication protocols. However, I don’t know if this option is suitable for my project because of the large number of sensors. If so, what kind of analog to serial converters could I use? Otherwise, could you please recommend any other way to perform this kind of connection? Thank you in advance. ------------------------------------------------------------------------------------------ |
