FSBM wiring and programming example

FSBM wiring and programming example

This section demonstrates how to wire the Guard I/O module and program the instruction in the safety control portion of an application.
This application example complies with ISO 13849-1, Category 4 operation.
TIP:
The standard control portion of the application is not shown in the following diagram.
Wiring Diagram
The wiring diagram shows how to wire a light curtain and four muting sensors to a 1791DS-IB12 module to illustrate the use of the Four-Sensor Bidirectional Muting instruction. The application includes a hold-to-run switch and a momentary push button for reset.

Module Definition
The following sections provide examples of how to use the programming software to set the Guard I/O module configuration operands.
When defining the module, setting the Input Status to Combined Status-Muting provides the smallest input packet possible and lets the muting lamp status be monitored. Choosing Test for Output Data lets safety logic control Test Output 3 to drive the Muting Lamp and Test Output 2 to drive the Clear Area Lamp.

Rockwell Automation
 suggests using Exact Match, as shown. However, setting Electronic Keying to Compatible Match is allowed.
The safety inputs that interface with the Light Curtain (Points 1 and 2) are not pulse-tested because the Light Curtain pulse-tests its own signals.
Module Input Configuration
FSBM_mod input config_v31
Configuring Test Output 3 for Muting Lamp causes the I/O module to monitor the lamp that is connected to this output.
