10. Redundant Systems
Figure 10-5: MRO-16-TS Module
10.3.8 MAO Module
The MAO module is not made with redundancy, therefore retrofitting of MAO modules is not
necessary.
As standard, it is supplied configured via solder jumpers for the CAN A.
10.4 Startup
The data stored in every MCP and MDO module contains information on system configuration,
i.e. the modules used, supply voltages, measuring points and alarm outputs.
Also included is the measuring point parameters (sensor type, calibration etc.) and switching
output parameters (switching direction etc.) stored in additional maps in every MCP and MDO
module.
After connecting the modules, the configuration stored in the SUPREMA memory has to be
updated according to the system status.
If the configuration listing does not correspond to the system status, “SYSTEM FAILURE“ will
be issued after startup.
10.4.1 Setting the System Configuration
Parameter Setting after Retrofitting
If a non-redundant system has been made redundant by retrofitting more modules, the
configuration and parameter setting is automatically transferred to the retrofitted MCP module.
The assumption is that only one MCP/MDO module has been retrofitted. There will be no
message concerning system configuration
(see figure 10-7 System Configuration Message).
This message will only appear if all three MCP/MDO modules has different configurations. In
this case, the system configuration message will appear, and the module has to be selected
from which the valid configuration is to be copied. After a new startup, this selected configuration
will be copied over to the other modules.
If the configuration is to be taken from the retrofitted module, the RESET button must be
