Hello Everyone,

I have been working on this project lately which uses the Alicat mass flow controller. The Alicat flow controller is connected to the micologix 1400 PLC using a RS-232 cable and I am connected to my PLC using the LAN cable. Can someone help me set up the communication/programming so that my RSlogix 500 program can read IOs from the Alicat flow controller. I have never used this before so I am not sure if I should use modbus protocol, explicit messaging, or is there any other way to get it done. Please help!

Thanks

Turns out the Alicat controller read and writes in ASCII. You just have to copy the files into String files and then convert it into float.
