Signal Source / Target Meaning
ACK_PASS_ACTUTOR From process (button) Acknowledgement by the user for manual reintegration
F00007_4_F_DO_DC24V_2A.ACK_REI To F-I/O-module data block of F-DO If "0->1":
F-DO is reintegrated.
F00001_4_8_F_DI_DC24V.ACK_REI To F-I/O-module data block of F-DI If "0->1":
F-DI is reintegrated.
Description of the network function:
F-DO and F-DI are reintegrated after acknowledgement by the
user:
■ Manual reintegration of the F-DO is necessary in the sample
code after channel or F-communication error.
■ Manual reintegration of the F-DI is necessary in the sample
code only after F-communication error.
Description: FB 215, DB1 (F_ESTOP1)
The block is a TÜV certified application block from the Distributed
Safety library.
Function and parameter of the F-blocks:

Operating instruction on the sample code
This chapter describes the operation of the functional example.
The operation is divided into different scenarios
Scenario Page
Normal operation 343
Manual reintegration after wire-break at F-DO 344
Automatic reintegration after wire-break at
F-DI
345
Reintegration after F-communication error 346
342 Functional Example No. AS-FE-I-011-V10-EN
The following prerequisites must be fulfilled in order to operate
the functional example:
■ The hardware configuration, the standard program, and
the safety program are located on the F-CPU
■ Emergency stop unlocked
As a description, tables with uniform structure are used below.
The columns of the table have the following meaning:
Column name Column content
"Step" Number of the operational step
"Action" Action of user
"State" The number marks the state reached after executing
the action. An overview of all status is
available at page 334.
"Comment" Comments on the step.
"Indicator Here the switch status of the five indicator
light"
lights and the SF LED is depicted which is set
after executing the action. Switched indicator
lights are marked with "1". (*1)
"SF-LED" The column indicates the status of the collective
error display on the F-I/O-module (red
LED). (*1)
(*1): To recognize more clearly which bits change during a
mode transition, they are shaded in gray: If a bit is shaded
gray, it has changed compared with its previous state.
