ASCII Comunication At AC500

I have a Problem in ASCII Communication After Upgrading From AC1131 to AC500

I have Connected COM2 to ASCII COM_Send Function Block this channel is connected to RS232 to 485 DA converter which connected to loop of 17 numeric displays its Type is XDM 14A-Manual Is Attached-.

When i changed checksum from none to CRC8-FBP 2 random displays read correctly but the others not.

Attached the online status of the old plc when its working properly and the new and Snapshots of Configuration.

What is the correct procedures to make ASCII Configuration of AC500 Project similar to old AC1131 Project?
