The following table describes the parameters.

Parameter Explanation

SEN_FIELD1 Position switch 1 (NC)

“1“ signal: Switch not applied.

SEN_FIELD2 Position switch 2 (NC)

“1“ signal: Switch not applied.

SEN_FIELD3 Memory bit as dummy

SEN_FIELD4 Memory bit as dummy

FIELD_BIT0

FIELD_BIT1

FIELD_BIT2

Number of the detection zone

(Bit 0, 1 and 2 of the cyclic output data)

Network 3

Here the FC REINTEGRATION (FC3) is called. FC3 is described further

below.

FB SET_ACT (FB3, DB3)

Network 1

The status of the SR flip-flop (#EN) is evaluated in OB1 as a condition for a

start.

In case of a detection zone violation, OSSD becomes “0“ and resets the SR

flip-flop (reset has the priority with this flip-flop bit). As a result, #RELEASE

(used in network 2) takes on the value “0”.

Network 2

The actuator (indicator light) is only switched on if both conditions are

satisfied.

• start condition fulfilled (COND1=”1”, see OB1)

• release was given (RELEASE=”1”, see previous network 1)
