Codesys V220.127.116.11 (Build NoV 17, 2015)
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 BAKA protocol which is not MODBUS RTU.
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 POU
If anyone has a code example in ST that demonstrates how the above can be achieved I would be most obliged for any assistance.
Please don't be offended if I test your patience with lots of potentially stupid questions whilst I learn.
