5 Operating modes of the Device EM12D-TMB
5.1 Operating mode: (system start)
The Modbus controller is initialised by applying the supply voltage. The device will carry out implemented
programme memory tests and self test routines. During this time a communication via the interfaces is not
possible.
5.2 Operating mode: (critical failure)
If a failure is detected during the self test routines, the Modbus controller will change into operating mode
“critical failure”. In the event of a critical failure, the device will also change into this operating mode. This
operating mode can only be discontinued by way of re-starting the device and it prevents the data exchange
via the interfaces. If the Modbus controller is in this operating mode, no communication is possible with the
superordinate control unit. The electronic circuit protectors cannot be controlled by it and remain OFF.
5.3 Operating mode: (non-critical failure)
If there are no valid or invalid configuration data available in the Modbus controller, it will change into this
operating mode. This operating mode will be left upon receipt of the correct module and slot parameters and
configuration data. The circuit protectors remain OFF.
