Register R/W Name Type Unit Description
1 R Measured insulation resistance uint16 kOhm The measurement result is provided as kOhms. The
register value 100 corresponds to insulation
resistance of 100,000 ohms. At the fastest, it
updates in seconds and at the slowest in hundreds of
seconds, depending on the measurement frequency
used.
2 R Measured capacitance uint16 0.1
uF The measurement result is provided as 0.1uF
intervals. The register value 5 corresponds to
capacitance of 0.5uF. It is updated at the same time
as the insulation resistance.
5 R/W Limit parameter of the
insulation resistance alarm
uint16 kOhm Read and written in kOhms. The register value 100
corresponds to 100,000 ohms. The minimum,
maximum and interval values are in channels 16, 17
and 18.
6 R/W The limit parameter of the
insulation resistance pre-alarm.
uint16 kOhm Read and written in kOhms. The register value 100
corresponds to 100,000 ohms. The minimum,
maximum and interval values are in channels 19, 20
and 21.
10 R/W Start-up delay, a device
parameter
uint16 s Read and written in seconds. The register value 2
corresponds to 2 seconds. The minimum, maximum
and interval values are in channels 31, 32 and 33.
11 R Password of the local user
interface uint16 none A three-digit pas sword. Range 000…999. Default
value 123. When needed, this can be used to prevent
the parameters from being set through the Modbus
RTU.
12 R Device alarm and status
register uint16 none Bit mask:
0x0001 = a fault or alarm related to insulation
resistance, corresponds to the INSULATION alarm
LED of the local user interface
0x0002 = insulation resistance pre-alarm
0x0004 = system test fault
0x0010 = fault in the TG or MG wire
0x0100 = system test active
0x0200 = internal calibration active (the insulation
level measurement values are invalid)
the statuses remain active until their cause has been
eliminated
13 R/W Start of the device system test uint16 none Start of the system test. Value 1 starts the test,
other values are not taken into account. IM-04DCCT
resets the request after reading it.
15 R/W Joint acknowledgement of
alarms
uint16 none Joint acknowledgement of unacknowledged alarms.
Value 1 acknowledges all alarms, other values are
not taken into account. IM-04DCCT resets the
request after reading it. This does not
acknowledge/inactivate active alarms.
16 R The lowest allowed value of the
limit parameter of the insulation
resistance alarm uint16 kOhm 10
17 R The highest allowed value of the
limit parameter of the insulation
resistance alarm uint16 kOhm 1000
18 R The resolution (jog) of the limit
parameter of the insulation
resistance alarm uint16 kOhm 50 if insulation resistance alarm limit 100 kOhm or
above
10 if insulation resistance alarm limit below 100
kOhm
19 R The lowest allowed value of the
limit parameter of the insulation
resistance pre-alarm uint16 kOhm 10
20 R The highest allowed value of the
limit parameter of the insulation
resistance pre-alarm uint16 kOhm 1000
21 R The resolution (jog) of the limit
parameter of the insulation
resistance pre-alarm uint16 kOhm 50 if insulation resistance alarm limit 100 kOhm or
above
10 if insulation resistance alarm limit below 100
kOhm
