Start-up procedure
Handling during start-up
S/S Off / S/S+Aut / S/S-Aut
This parameter sets the handling during start-up (cyclical sending of data via the
CAN bus). See also Start/Stop of Cyclically Transmission of Data Via CAN Bus on
page 17.
S/S Off
......... no start/stop (for operation with GCP)
With switching-on the unit it sends with the configured sending baud
rate data via the CAN bus. Interruption of sending is not possible.
S/S+Aut
....... Start/stop with auto start
With switching-on the unit it sends with the configured sending baud
rate data via the CAN bus. Interruption and re-start of sending is poss-
ible via the CAN bus.
S/S-Aut
........ Start/stop without auto start
Sending of data is started after this has been enabled through a CAN
bus signal. Sending can be interrupted and re-start as often as neces-
sary via the CAN bus.
Default setting: no start/stop
Note:
•
To enable the unit to send data a sending baud rate (
≥
20 ms) has to be confi-
gured (see above)!
•
Auto start is enabled one second after applying the power supply.
•
Start/stop commands would accepted one second after receiving of the message,
too.
If you configure via the CAN bus (D-1):
0.................... no start/stop
1.................... start/stop with auto start
2.................... start/stop without auto start
CAN error delay (s)
Triggering time for CAN faults (timeout)
0 to -99.98 s
If you configure "0" in this screen an CAN fault would not lead to an alarm. If the
unit did not receive data within this configured limit a CAN fault is recognized. If a
relay has been configured (see further below) this would be triggered. The status of
the rest of the relays would not be changed or the relays would be set to base setting
(depends on configuration). Additionally in Byte 7 of the CAN sending message a
fault bit is set. If the CAN still allows this message can be received by another CAN
participant.
Note:
It is not allowed to lower this time under the sending baud rate of the corresponding
unit.
CAN error
self-acknowledgment
CAN alarm acknowledgment
YES/NO
Here you can configure the type of acknowledgment for CAN alarms.
YES
.............. self acknowledgment
The alarm message is canceled right after the CAN fault has been
cleared.
NO
................ no self acknowledgment
The alarm message is canceled right after the CAN fault has been
cleared and a acknowledgment has been received.
Note:
Acknowledgment can be done via the CAN bus or the configured discrete input (if
configured).
