Hi all,
I would like to read ASCII weight from 2 scales into a single serial port on a MicroLogix 1400 using RS-485. I haven't seen any posts on this before, is this even possible? I will be integrating 2 scales that are addressable and spit out thier weight 1 / second (RS-485 ASCII). I would like to wire them up on a RS-485 multi-drop network and monitor each one individully using the same comm port on a MicroLogix 1400. I currently have one of the scales setup and working with the ML1400 by using either port 0 or 2 as ASCII and reading the data with the ABL and ARL instructions but wasn't sure how to accomplish this without using a gateway as it looks like the the MSG instructions would only be used for Modbus RTU, correct? Thanks in advance for any advice.
