hello everybody,
I need to be able to control the MTL serial text display http://www.mtl-inst.com/product/mtl646_647_indicators/ by a dedicated Modicon M340 PLC.
This is my first real-world PLC project, but ascii is something completely new to me. I've done some reading on ascii function with the rslogix (I only have access to rslogix for the moment), and still not sure about it. Can somebody in this forum check my codes, or suggest any better solutions?
For example:
<CS>
<WT example>
A -------------------------
---||---| AWT |
| | Channel 0 |
| | Source ST9:0 |
| | Control R6:0 |
| | String Len 0 |
| | Char Sent 0 |
| | Error 0 |
| -------------------------
|
| -------------------------
|-| AWT |
| Channel 0 |
| Source ST9:1 |
| Control R6:1 |
| String Len 0 |
| Char Sent 0 |
| Error 0 |
-------------------------
Define the following strings in data file ST9:
ST9:0="<CS>"
ST9:1="<WT example>"
Thanks in advance
