  1. Micro820 to External RS-232 Display

    Hi Joe, Thanks for the advice. I've searched through the sample code library, the examples seem more helpful for intermediate users that are comfortable with ladder logic. I'm searching for a how to crawl guide before I can follow the how to walk one...   I'm using functional block diagrams for my program and I have been unsuccessful at finding for a simple "hello world"-style walkthrough example for the micro800 series. I just need to understand basics of the connected components workbench quirks such as how to write to outputs or relays (digital/analog), how to detect inputs...and of course writing data to the Tx port of the controller. I haven't been able to find much on the sample code library helpful in order to understand how to do this...   If anyone has any other resources that are more beginner-friendly I'd really appreciate it.
  2. Hello,  I am working on a project to connect a PLC (Micro820 by Allen Bradley) to a simple RS-232 alphanumeric OLED display. I am not too familiar with structured text language, but I have worked with micro-controllers that use similar high-level languages (mostly C-based).  My question is: is it possible to use connected components workbench to program my Micro820 to output ASCII commands to an off-the-shelf RS-232 alphanumeric display? Are there libraries that make life easier to do this?  I welcome any recommendations to related reference material or command tutorials, thanks!
