Ac500 to Flowmeter RS485 Serial communication
Hello, ABB AC500 experts,
I am having hard time understanding why there is no communication between the AC500-ECO PM554 and Emerson FB1200 Flow meter since everything is configured correctly. I am getting an Error code 8211 on the Com_mod_master function Block (Please see the image for connection diagram and function block that is used for Master RS485-Configuration) on PM554 ECO PLC. I would like to know what it might have gone wrong so our ABB PM554 ECO PLC has not been able to talk to the Emerson Flow meter.
I would appreciate if some one can shed a light on this issue.
Thanks
Rob

Hi,
It seems you don't have a connection to the slave. There are many things to check.
Which are your COM1 settings?
Here is some example for master mode - check if the communication parameters corresponds to these of your slave.
