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 communications 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 communications is established.
