Switch On Heating; Channel Control Via Setpoints - Siemens SIPLUS HCS Operating Instructions Manual

Functions
9.2 Power output control
9.2.3

Switch on heating

Switch on heating
To control the power outputs, the heating must first be activated. This is done via the cyclic
data.
Heating status
On
Off
Note
A time-delayed start-up or channel soft start only occurs if heating is "On".
Time-delayed channel start-up
To reduce the load on the supply system to a minimum, the power outputs are always
switched on in sequence upon start-up. The sequence is as follows:
1
2
3
4
5
Depending on the configuration, overall startup can take up to 3 seconds.
If during operation a channel is switched off and then on again, switch-on takes place
immediately.
9.2.4

Channel control via setpoints

It is possible to control the channels using only the setpoints in the cyclic data. In this mode,
it is not necessary to combine channels into fields and to assign field setpoints.
The operating mode setting in the cyclic data (production, standby) is not relevant in this
case.

Description
Channels are activated
Channels are deactivated.
The user has specified the field setpoints and the channel setpoints
The user activates the required operating mode

Several POMs are activated with a time offset in ascending slot order
Within each POM, the channels of a phase are also started in sequence. The channels of the
three phases are activated "simultaneously" in each POM.
