The Unit does not always transfer input data to the mapped
PLC data area(s). If the Unit cannot provide updated input
data during an I/O refresh, no data will be transferred. This will
typically occur if the fieldbus cycle time is larger than the PLC
cycle time, or if the DP communication has been inhibited.

remote node error.
The master will only branch into Auto_clear mode when this
has been enabled in the configuration (see 4-3-7, Bus
parameters). In Auto_clear mode, the network state bits
indicate Stop, and the DP-ERR LED is flashing. IR n+3 will
indicate more details about the cause of the error.
To recover from Auto_clear mode, the C200HW-PRM21 must
be restarted (Power OFF / ON or restart bit in AR01 / SR281).
