Address Name IQ Description Notes
0 Status n/a Describes the status of the unit (output enabled, faults, mode, etc). See register description below
1, 2 Fault_Bits_HI/LO binary Ssytem fault bits, each bit of the number means a different fault. See fault bits description. 3
3, 4 Vmonitor_HI/LO IQ15 / FP Output voltage monitor. 1.0 = nominal current of one module (167A / 250A) 1, 2
5, 6 Imonitor_HI/LO IQ15 / FP Output current monitor. 1.0 = nominal voltage (60V / 40V) 1
7, 8 Pmonitor_HI/LO IQ15 / FP Output power/process monitor. 1.0 = nominal power of one module (10020W / 10000W) 1, 2
9 Existing_Modules_Qty Int16
Number of modules that are recognized by the unit. Depends on the number of modules that were
discovered by the master controller.
