The following signals are available for safeethernet communication:
Maximum time in ms that may elapse between
the reception of two valid messages
Time in ms that elapsed while waiting for a
response to the last message sent
[UINT]
0 (CLOSED)
1 (TRY_OPEN)
2 (CONNECTED)
CLOSED: No connection
TRY_OPEN: Attempt to establish the
connection (state valid for active and passive
sides)
CONNECTED: The connection is established
(active data exchange and time monitoring).

Used by a user program to close a safety-
related protocol or enable it for operation. Refer
to the following table for the corresponding
description.
Table 58: System Signal of a safeethernet Connection for Setting the Connection Control -
CPU OS up to V7
The following commands can be used for the Connection Control signal:
After a peer-to-peer communication loss, the controller attempts to
reestablish communication in the following cycle. This is the default
setting.
TOGGLE_MODE_0
TOGGLE_MODE_1
After a communication loss, the user program can re-establish the
connection by changing the TOGGLE MODE.
If TOGGLE MODE 0 is active and the communication is lost
(Connection State = CLOSED), a reconnection is only attempted after
the user program switched the TOGGLE MODE to TOGGLE MODE_1.
If TOGGLE MODE 1 is active and the communication is lost, a
reconnection is only attempted after the user program switched the
TOGGLE MODE to TOGGLE MODE_0.
Peer-to-peer communication is off
No attempt made to establish the connection
