Safety Function Switching

The global safety function is activated on the Extended settings tab with the parameter Device safety and the global settings are parameterized there.

The effect of the safety function can be parameterized here for each channel. You can enable the safety function individually for each switching channel.

Ext. 1/2 Output 1-8 -Switch: Switching	Safety function
– Safety and alarm settings	Safety function	Disabled Enabled
– Safety and alarm settings	Behavior at start of safety	No reaction Pressed Released Blinking (5s cycle)
	Behavior at end of safety	No reaction Pressed Released Follows current value
	(Cycle time surveillance for Safety object" > 0)
	Behavior at exceeding cycle time	No reaction Pressed Released Blinking (5s cycle)

The safety function is activated if the safety object receives a telegram with the object value that you defined with the parameter Device safety (). The reaction is defined by the parameter Behavior at start of safety.

If the safety object receives a telegram with the object value opposite of that for activation, the safety function is canceled and the output relay adopts the state that you defined in the parameter Behavior at end of safety.

The device then waits for a telegram from an external sender within the globally set cycle time. If such a telegram is not received within the monitoring time, the parameter Behavior at exceeding cycle time is used to determine what is to happen.
