Messages, Codes and Self-test Numbers Appendix B

Remote I/O Communication

Loss

When communication fails on a remote I/O network:

• Object states are maintained and the message No PLC

Communication is displayed on the screen.

• If Block Transfers are defined for the application, but no BTR or

BTW instructions are received, another message appears when

the Block Transfer Timeout occurs.

These messages continue to display until communication is

established. If a write operation is attempted to the logic program

controlling the PanelView objects, the terminal will display the

message Error: Write to Logic Controller failed.

If a PanelView object is activated during a communication loss, the

object retains its new state and sends this state value to the controller

when communication is established.
