ACE 3640 Running Modbus Master
Hi Experts,
I am relatively new to the Ladder logic based programming and I am working connecting a Motorola ACE3640 to a SEL751 Relay using the MODBUS protocol.
Unfortunately when ever I load the Ladder application I created on to the RTU I get this error
"# 834 Userrom plc module, function prv_userrom_plc_scan Iolink definition problem of plc column !"
According to the Error document provided by Motorola, it
"May indicate system software problem. Consult product group."
So, initially I was presuming that there was something wrong with the system software, but I tried loading other applications and they run well. So, I am pretty sure it is my ladder logic which is the problem.
Has anybody achieved this communication before, if so would anyone of you be willing to share how it is done?
Thanks
