Controlinc 1746-C (Version 5.21) Network Master Users Guide (2004-11-18)

Example Tables [16 & 17] Feedback (48-node network) …

Characteristics:

• To make it more meaningful, tables [16 & 17] are in hex because of bit indications.

• Monitoring is being performed on unit [1]

(bit [15] = 1 in table [16])

• The PLC commanded the 1746-C to set all the coils on units [2 – 6]

(bits [15-13] = 111 … 0xE0xx in table [16] … the value prior to the 1746-C acting upon

the command)

(bits [5-3] = 111 in table [16])

• The 1746-C processed the command and wrote the new coil states to actuators [2-6].

(bits [15-13] = 110 … 0xC0xx in table [16])

• Units [2-6] all have all 3 discrete outputs on.

(bits [5-3] = 111 … 0x0038 in table [17])
