watch table in the project tree.
2.
The required command "RESET!" is
specified as default value of data
record 190 (see chapter 4.2.25).
3.
In case of several HCS, select the
HCS to be reset via
"LHcs4x00_Tags".control.onHCS.
Write "190" to tag
"LHcs4x00_Tags".control.dsNum and
set bit
"LHcs4x00_Tags".control.writeData
for transferring the command.
4.
The transfer of data record 190 has
the same effect as an interruption of
the 24 V power supply of the HCS: All
data records are reset (including the
field assignment).
5.
Then reset bit
"LHcs4x00_Tags".control.writeData.
8.1.8
Monitoring the power channels for loads connected in parallel
The POM4220 Highend offers the option to detect a partial load interruption for
heating elements connected in parallel. The parameters for detecting the partial
load interruption can be set for each channel in the hardware configuration or via
data record 2. This offers support for commissioning and enables you to adapt the
parameters during operation (e. g. in case of more than two heating elements
connected in parallel). Additionally, you can read out the measured values (current
and power) of the POM4220 Highend for each channel via data record 203.
