Field value

Resulting setpoint = field value setpoint * channel value

Field assignment

no
Channel value
setpoint
Without field assignment, the actual channel value results from the setpoint
channel value via the output address area for the respective POM.
With the field assignment, the actual channel value results via the formula:
Resulting setpoint = field value setpoint* channel value
setpoint/100
In field operation, it makes sense to set the channel value setpoints to 100% for
each POM and to control the field only via the field value setpoints (data record 150
for “production” operating mode and data record 151 for operating mode
“standby”).
The not required output channels from the diagnostic evaluation can be excluded
via data record 152.
In the default setting of data record 160, the fans integrated in the POMs are
switched depending on the temperature. However, you can also switch them on
permanently.
Data record 190 enables you to reset the HCS. This function currently is not
supported by the library.
The measured values for internal temperature and network frequency are read via
data record 200. Here, the POM4320 additionally supplies the mains voltages U
L12
,
U
L23
and U
L31
and the POM4220 Highend the mains voltages U
LX1
and U
LX3
,
respectively.
