The assigned status variable becomes TRUE when the corresponding state is achieved.
3.4.7 Recording Events
The processor module collects the events:
created by I/O modules
created by the processor module itself
The processor module stores all the events in its buffer. The buffer is part of the non-
volatile memory.and has a capacity of 5 000 events.
The processor module arranges the events from different sources by the time of their arrival
and does not sort them by their timestamp.
If the event buffer is full, no new events can be stored as long as no further events are read
and thus marked as to be overwritten.
The OPC server can read the events and make them available to external systems for
evaluation and storing.
3.4.8 Protocols and Interfaces
Communication with external systems occurs via the Ethernet interfaces. The interfaces are
part of a 10/100/1000 BaseT switch.
The four RJ-45 connectors are located on the connector board. The LEDs on the front plate
of the module indicate the connections statuses. For more information, see Chapter
3.4.11.
On these interfaces, the module can process the following protocols:
The safety-related protocol safeethernet
Connection to the PADT
Parameter Value
Number of connectors 4
Transfer standard 10/100/1000 Base-T, half and full duplex
Auto negotiation Yes
Auto crossover Yes
Connection socket RJ-45
IP Address Freely configurable
1)
Subnet Mask Freely configurable
1)
Supported protocols safeethernet, PADT
