Hello,
I am currently working on a project for the company i work for. I am new to PLC programming and need some help!! desperately!
We are creating a new batching sytem for a manufacturig process. We are using an allen bradley micrologix 1200 and rs logix 500.
The channel configuration is set correct to our knowlege:
Driver-ascii
Baud-9600
parity-none
termination characters-d and ff
no handshaking
Now comes the problem!
We need to get a signal or reading out of a practicon PR444ZV weight contoller using Ascii instruction,Our knowlege of ascii is very limited. we seem to be able to transmit characters, more than just the carriage return, using the ascii write with append (AWA) command. when it comes to undertanding the read (ARD)and clearing buffers ect we seem to be gettin lost. Any basic ascii logic , examples would be marvelous!!
Thanks in advance.
