Communication Problem in Mitsubushi PLC A2SH with OPC 4.5.1

[suresh.r]

While communicating with Mitsubushi PLC A2SH thru OPC 4.5.1 , it displays time out error , the settings of the Com port of the system is Baud = 9600, Parity = odd
Data bits = 8 Stop bits = 2, Flow Control = None . The same setting is done in the OPC & Mistubushi PLC Comm protocol. Iam using Labview DSC to communicate with PLC with OPC 4.5.1. How do i solve this Comm Problem in what steps.

You might increase the 'Recieve timeout' from 250ms to some higher values on the object (driver) and you might increase in Options >> Serial Ports... >> Receive Gap from 20 to a bigger value like 50.

Hope it helps.

PS: I've not tried it with this particular PLC, though.
