RESET, OFFLINE
When switching power ON the B310 is in RESET state. It switches to STOP state by starting TwinCAT. If TwinCAT is stopped or a critical bus error occurred the operation mode is switched to OFFLINE. If the unit is in OFFLINE state it has no activity on the fieldbus.
STOP
After the start of TwinCAT or during accessing the bus configuration via the system manager the B310 in in STOP state. The unit has bus activity but does not exchange data with other bus participants. During TwinCAT start or I/O-Reset the unit is in STOP mode. It switches to RUN state automatically, when initialization phase is completed.
RUN
In RUN state the B310 unit starts to communicate with the project defined participants. If the TwinCAT task is started the data exchange takes place otherwise the unit starts reading and sending diagnostic data to the bus master. If the bus master switches to CLEAR mode (all outputs are set to 0), the unit behaves as the PLC program defines this state. If the master switches back to OPERATE mode the unit automatically resume its work.
DIA
The DIA LED is reserved for further functions and has no meaning so far.
