 Communication status
AH10/15SCM-5A provides the status of Modbus communication. Data exchanges include
reading data from bit devices/word devices, and writing data into bit devices/word devices. The
status of executing a data exchange is represented by the state of a bit in a data register. For
example, if D100 is an initial register in which the states of the bits represent the statuses of data
exchanges, the status of exchanging data 1 is represented by the state of bit0 in D100, and the
status of exchanging data 2 is represented by the state of bit1 in D100, and so on.
