Please Note
The diagnostics mode reduces the available address space.
• When planning your CPX terminal, consider that the number of input and output bits
available for communication is reduced with usage of the diagnostic mode.
Subsequent activation of the diagnostics mode requires a reconfiguration.
• Observe that the CPX-internal I/O image can be displaced during subsequent activa­
tion of the diagnostics mode.
• In this case, repeat the network configuration.
