WARNING

The time to be set at parameter PT of the FB F_TON depends on the

application. Generally, this time should be as small as possible. For

times larger than 1 sec additional safety measures should be

considered.

Network 6:

For a set #ERR_SW_TIME bit, the bits 0, 1 and 2 of the cyclic output data

are reset. The bits determine which detection zone is active. Resetting

these bits will cause the laser scanner SIMATIC FS600 to reset the OSSD

bit. In the safety functional example, resetting the OSSD bit causes the

indicator light to be switched off (see FB 3, network 1 and 2).

FC REINTEGRATION (FC3)

In the FC3 a re-integration is implemented for the following components:

• Laser scanner SIMATIC FS600 (network 1).

• F-DO (network 2).

• F-DI (network 3).

The memory bit #REINT is prepared for the F-DO. The F-DO is

reintegrated with a positive edge at the memory bit #REINT.

WARNING

In this safety functional example, passivated components are re-

integrated automatically. Use the automatic re-integration for your

application only if it will not cause any hazards.

A passivation is indicated by an illuminated LED “SF” on the F module. The

reintegration of an F module may take about one minute.
