When serial (interface) Mode 4 is selected, this parameter is loaded with
a variable input from the serial (interface) port.
Refer also to parameter 11.13.
When serial (interface) Mode 4 is selected, this parameter is transmitted
to the next Drive down the line.
Special Parameters in Menu 16
This parameter indicates the state of the CTNet network.
A value greater than 0 indicates a healthy network, with the value
representing the number of messages per second received by the node.
A value of 0 indicates a healthy network, but no data is being
transmitted. This usually indicates that there is no node configured to
generate cyclic synchronisation messages.
A value of -1 indicates an unhealthy network caused by cabling error, no
terminationresistors,noothernodesonnetwork,etc.
A value of -2 indicates initialisation failure, such as baud rate mismatch
or illegal address. Often this will be accompanied with a trip on power-
up.
This parameter is only used when the DPL program has been compiled
with the debugging information switched on. The value it gives indicates
the approximate line number within the DPL program where a run-time
error occurred. If no run-time error has occurred, the value will be
meaningless.
