3. Set parameter 200
Parameter200 stipulates, how the combustion manager reacts to the heat demand
via Bus or control circuit(T1/T2). The parameter can only be changed via a PC us-
ing VisionBox Software.
Check parameter 200 and change value if necessary.
The change will be adopted after maximum 20 seconds or at restart of the com-
bustion manager.
Value Function
0 Only control circuit activated (T1/T2), factory setting.
Heat demand via Bus is ignored.
1 Control circuit(T1/T2) releases heat demand via Bus.
A heat demand via Bus is only accepted if the control circuit(T1/
T2) is closed.
After 10seconds of bus separation, the combustion manager ini-
tiates a control shutdown.
2 Bus default and control circuit(T1/T2) activated.
Change-over to the control circuit(T1/T2) occurs under the fol-
lowing circumstances:
after 10 seconds Bus separation,
if "Deactivate heat demand via Bus“ is set.
Profibus [ch.7.1.1]
Modbus [ch.7.2.1]
3 Only Bus default active, with controlled shutdown.
The control circuit (T1/T2) is ignored.
After 10seconds of bus separation, the combustion manager ini-
tiates a control shutdown.
If there is no bus connection, the combustion manager remains in
standby mode.
4 Only Bus default active, with lockout.
The control circuit (T1/T2) is ignored.
After 10seconds of bus separation, the combustion manager ini-
tiates a lockout.
If there is no Bus connection, the fault appears immediately. The
combustion manager must then be connected to the Master
whilst in lockout.
4. Install GSD file
Only in conjunction with Profibus, skip this step with Modbus.
Install GSD file supplied in programming tool.
5. Configuration
Stipulate configuration of input and output data.
