Communication status AH10SCM-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. The TCP keepalive period by default is set to 30 seconds. D500 is an initial register in which statuses of data exchanges are stored. Users can enter MODBUS Advance to alter the initial register. 8-26 Dn Bit b15 b14 b13 b12 b11 b10 b9 b8 b7 b6 b5 b4 b3 b2 b1 b0 No. 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 D (n+1) Bit b15 b14 b13 b12 b11 b10 b9 b8 b7 b6 b5 b4 b3 b2 b1 b0 No.
