Field type 2 combines any output channels. You can specify up to 24 channels
for each field. A total of 32 fields can be defined. The sequence of the list of
channels is irrelevant. The list of channels has to be without gaps (“0” is
interpreted as the end of the list). It is not permitted to assign one channel to
different fields. The field last assigned (the data record written last) determines
the actual assignment of the output channel here. The output channels are
numbered continuously (e.
g. for HCS4200 POM2 “Lowend”: channel 17 to
32).
Selecting one field type prevents access to the others. If, for example, data record
100 (field type 1) is read or written to, it is no longer possible to read from or write
to data record 101 to 132 (field type 2).
The SIPLUS HCS (including selection of the field type) is reset upon returned
voltage (24 V) or via data record 190.
Depending on the operating mode, the setpoint for each field is specified via data
records 150 (production) or data records 151 (standby). Both data records contain
the 32 setpoints for the 32 fields. For field type 2, the first setpoint is assigned to
data record 101 (data record number minus 100).
The actual value (resulting setpoint) for each output channel results as in the
following flow chart:
