ACS: Parameter download does not work, why?
Make sure that the parameter tree is expanded prior to download.
Wrong
Download sometimes also works with a collapsed parameter tree.
Why can I not parameterize the controller via HandyTool in service mode (n6)?
There are two reasons:
• Download (HandyTool, ACS or ETS) was not exited correctly (interrupted).
• The controller was set to "unloaded" via ETS.
Solution: Carry out a full download (via HandyTool, ACS or ETS).
The parameter download was probably interrupted or exposed to interference.
Download the parameters again.
Why does a controller with thermal valves not respond immediately when it is
enabled in the plant graphics in the ACS view and in the DESIGO graphics?
After start-up, the thermal valves are preheated first. This is not shown in the plant
graphics.
However, if the room temperature is outside the dead band during this period, the fan
switches to Speed 1.
Why doesn't the master/slave binding work?
Master/slave zones must be identical for master and slave.
Create master/slave group addresses and add communication object.
