Note: Projects with network variables
43098
If network variables and safety network variables are used simultaneously, the user has to observe the
following sequence for the transmission of the applications to the device:
1 Create safety network variables
►
Device 1: Create and configure safety network variable list (transmitter)
►
Device 2: Create and configure safety network variable list (receiver)
►
Optional: Create and configure more transmitter/receiver pairs
2 Transfer applications to devices
►
On all devices: Log in to standard PLC and the fail-safe PLC.
►
Transfer boot applications to both PLCs
►
Check if safety NetVars function correctly.
3 Log out
►
Log out from the standard PLC.
4 Create standard network variables
►
Device 1: Create and configure network variable list (transmitter).
►
Device 2: Create and configure network variable list (receiver).
►
Optional: Create and configure more transmitter/receiver pairs.
5 Transfer application to devices
►
On all devices: Log in to standard PLC.
►
Transfer boot application to standard PLC.
►
Check if network variables and safety network variables function correctly.

Teach code sequences of the safe AS-i slaves
43012
To teach the code sequence of a safe AS-i slave:
Requirements:
>
Safe AS-i slave is connected to AC4S and addressed.
>
Parameter "EnableStartupTest" for all safe AS-i input slaves is activated.
>
All safe AS-i input slaves are enabled (e.g. E-stop: unlock).
>
Safe application is stored on the device and has been started (→
Load safe application to AC4S
>
Code table is blank.
1 Teach code sequences of a safe AS-i slave
>
AC4S requires testing for safe AS-i input slave (OSC message).
►
Confirm safe AS-i input slave and unlock again (switching sequence: lock
unlock)
>
Safe AS-i slave transmits code sequence to AC4S.
>
AC4S fills code table with code sequence of the safe AS-i input slave.
>
Code sequence of the safe AS-i input slave is taught.
2 Optional: Teach more code sequences
►
Repeat step 1 for additional safe AS-i input slaves.
