Input signal conditioning<br />

The incoming operand AREA_PROTECTED can be linked to the<br />

conditioned signal transmitted from one or several protective<br />

doors (see page 452).<br />

You can use, for example, the function block "F_SFDOOR"<br />

from the Distributed <strong>Safety</strong> library to evaluate the signals<br />

transmitted from a protective door:<br />

Function block "SF_DOOR"<br />

Depending on the respective application, the incoming operand<br />

ENABLE_MOTION can be linked to the conditioned signal<br />

of an acknowledgement button.<br />

You can use, for example, the function block "EN_SW_1" from<br />

the SIMATIC S7 F/P library to evaluate signals transmitted from<br />

an acknowledgement button.<br />

The block description of the SIMATIC S7 F/P V2.0 press safety<br />

library provides a detailed description of this block.<br />

Function block "EN_SW1"<br />

In order to transmit the axis enable of the function block<br />

"F_DRIVE" via the output parameter ENABLE_AXIS (see fig.) to<br />

two outputs of a fail-safe output module, you have to link a<br />

static variable such as ENABLE_AXIS to the output block.<br />

The subsequent network links this static variable to the appropriate<br />

outputs by means of parameter assignment.<br />

Axis enable link<br />

Function Example No. MC-FE-I-004-V11-EN 459<br />

Ex. No.<br />
