FB FIELD_PAIR_SWITCHING (FB4, DB4)

The following table describes the parameters.

Parameter Explanation

SEN_FIELD1 Position switch 1 (NC)

SEN_FIELD2 Position switch 2 (NC)

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, bit 1 and bit 2 of the cyclic output data)

A maximum of four zone pairs can be activated. However, only one zone

pair can be active at any time. In the safety functional example, either zone

pair 1 or zone pair 2 can be active. It is possible to switch from zone pair 1

to 2 and from zone pair 2 to 1. It depends on the cyclic output data (bit 0, bit

1, bit 2) which zone pair is active.

The following assignments apply:

FIELD_BIT2 FIELD_BIT1 FIELD_BIT0 Active

zone pair

Note

0 0 1 1

0 1 0 2

Implemented in the

safety functional example

0 1 1 3

1 0 0 4

Prepared in the safety

functional example

The states of these three bits are determined by the status of the position

switches (SEN_FIELD1, SEN_FIELD2).

Note

During zone pair switching, the PC adapter must not be connected. The

PC adapter must not be plugged in at the SIMATIC FS600.
