Enable safety objects
Options:
•
yes: The communication objects device safety are enabled. Three further parameters appear:
36 2CDC 505 084 D0203 | SE/S 3.16.1
no
yes
Function safety priority 1
Options: inactive
enabled by object value 0
enabled by object value 1
With the Function safety priority 1...3, a customized trigger condition (safety disconnection) can be
defined for each priority. With safety disconnection, one communication object Safety priority 1...3
becomes visible each time. These communication objects relate to the entire device. However, eve-
ry output can react differently to the receipt of a telegram. The reaction of the output is parameter-
ized in the parameter window
•
inactive: The Function safety priority 1 is not used.
•
enabled by object value 0 Activation of the safety is triggered if at communication object Safety
Priority 1, a telegram with the value 0 is received. The following parameter appears.
•
enabled by object value 1 Activation of the safety is triggered if at communication object Safety
Priority 1, a telegram with the value 1 is received. The following parameter appears:
Control period in seconds
[0...65,535, 0 = inactive]
Options: 0...65,535
This parameter defines the control period of the function Safety priority 1. If a telegram is received
in this time with the defined triggering condition as defined in parameter Function safety priority 1
on communication object Safety priority 1, or if a telegram is not received within this monitoring pe-
riod, it will be triggered. Should the communication object Safety priority 1 receive a telegram that
does not fulfil the trigger conditions, the control period is reset and restarted.
•
0: This is no monitoring. However, the Safety priority 1 is triggered when a telegram with the
defined triggering condition, as defined in parameter Function safety priority 1, on communica-
tion object Receive Safety priority 1 is received.
Note
The control period should be at least twice as long as the cyclical transmission time of the
sensor, so that the immediate absence of a signal, e.g. due to a high bus load, does not immedi-
ately result in an alarm.
