Codesys V2.3.9.49 (Build NoV 17, 2015)
WAGO 750-881 Controller
WAGO 750-652 RS232/485 Serial Interface
Beka BA488C Serial Text Display
PLC_PRG in ST
Good Morning all,
I'm a newby to Codesys and have been tasked to establish communications from 750-652 (Master) to Beka BA488C (Slave) to send ASCII Text under BEKA protocol which is not MODBUS RTU but MODBUS ASCII.
I need to gain an understanding of:
What Libraries do I need to add to the project if at all
How to configure 750-652 as Master
What variables I need to declare in the POU or if having added the library, the required variable are automatically declared.
If anyone has a code example in ST that demonstrates how the above can be achieved I would be most obliged for any assistance.
Thank you.
