Communication status data. When the module is unmounted, the module type is not correct, or when communication errors
occur frequently, the corresponding bit turns to “1.”

CHANNEL STATUS
Analog input modules check high/low limits and ADC. When there is an error in one or more channels, the bit corresponding
to the channels turns to “1.” The bit corresponding to unmounted channels turns to “1.”
DC current output modules check output wire breakdown to alert as an error. The bit corresponding to the channels turns
to “1.”
In the Data Allocation Mode 2, among the two bits assigned for each module, the least significant bit is used for channel 1 of
a two-channel analog module or for a discrete module.
