Table 4-10. Status Register Bits
Bit Field Value Description
1 STATUS_BIT_ON
0
1 The unit is off.
The unit is on.
2 STATUS_BIT_FAULT
0
1 No faults.
There is a fault.
3 STATUS_BIT_ANALOG_PROG
0
1 The unit is not enabled through analog programming.
The unit is enabled through analog programming.
4 STATUS_BIT_MODBUS_PROG
0
1 The unit is not enabled through Modbus programming.
The unit is enabled through Modbus programming.
5 STATUS_BIT_IMODE
0
1 The unit is not in current mode.
The unit is in current mode.
6 STATUS_BIT_VMODE
0
1 The unit is not in current mode.
The unit is in voltage mode.
7-16 Not used
Notes:
1.
If both voltage and current mode signals are “1” this indicates that the unit is in power/process mode.
2. The fault bit will stay high until the Command register COMMAND_BIT_RESET_FAULT bit is set to “1”.
3. In case of a fault, the Fault_Bits will show the reason of the fault with an error code. Each fault is indicated by one bit so that
multiple faults can be indicated simultaneously. Use the Fault_Bits descriptions below to decode which fault(s) are being
annunciated.
Table 4-11. Fault_Bits Register
Code Name Description
0x1 FAULT_MODULE_FAULT One or more modules have reported a fault.
0x2 FAULT_OUTPUT_IMPEDANCE
The output impedance has exceeded the maximum or is below of
minimum limit.
0x4 FAULT_COMMAND_ERROR
The unit reports that it cannot accomplish with the programmed current,
voltage and power.
0x8 FAULT_MASTER_HARD_FAULT The master board has detected a hardware fault.
0x10 FAULT_MASTER_SUPERVISORY The master board has detected a fault in the variables of supervision.
0x20 FAULT_ANALOG_PSETPOINT
When using 4-20mA analog programming, this signal indicates that the
input current is below 2mA. This may indicate an external problem with
the 4-20mA loop.
0x40 FAULT_ANALOG_ISETPOINT
0x80 FAULT_ANALOG_VSETPOINT
0x100 FAULT_REMOTE_SNS_ERROR
There is too much measurement error in remote sensor. This may
indicate an external problem with the remote sensing cable.
0x200 FAULT_MODBUS_TIMEOUT
No Modbus communication activity has been detected. This may
indicate an external problem with the master Modbus device.
0x400 FAULT_MASTER_WARNING
The master board has detected a warning in the variables of
supervision.
0x800 FAULT_NO_RESPONSE_MODULE One or more modules did not respond to the internal communication.
0x1000 FAULT_REPEATED_MODULE_ID
The master has more than one module connected with the same ID
value.
0x2000 FAULT_TOO_MANY_MODULES
The master is connected to more than the maximum of 32 modules.
This may indicate that too many power supplies are connected in
parallel.
