5.3 Use CODESYS online help 42557
This manual only describes the integration, configuration and the programming of the AC4S using the
CODESYS development system.
For the description of user actions and user interface elements the CODESYS terminology will be
used.
Standard functions and methods of CODESYS will not be described. At the beginning of each section
there will be a reference to the corresponding chapters of the CODESYS online help.
To access the online help of the CODESYS development system:
►Start CODESYS.
>The CODESYS user interface appears.
►Press [F1].
>Online help of the CODESYS development system appears.
►Familiarise yourself with the CODESYS development system! In particular with the
following topics:
Names and functions of the user interface elements
Basic menu functions
Programming techniques and methods for data retention
>
5.4 Create user account 43243
►Familiarise yourself with the following CODESYS functions!
Safety user administration and access control:
→Online help > Add-Ons > CODESYS Safety > Safety user administration and
access control
Safety user configuration:
→Online help > Add-Ons > CODESYS Safety > Safety user configuration
Safety-relevant objects and functions of a project must only be carried out by a user who is a member
of the user groups "Safety" or "Safety.ExtendedLevel".
To create a user:
►Select [Project] > [Project settings]
►CODESYS user administration appears.
►Create user and add required user group.
►Create password.

5.5 Configure programming interface 43271
To transfer the created project to AC4S a valid communication path has to be configured between the
programming system CODESYS and AC4S.
Standard PLC and fail-safe PLC of AC4S use a separate hardware. Therefore it is necessary to set
the communication paths for both controllers separately.
>
5.5.1 Set communication path of Standard PLC 43042
The following interfaces can be configured as programming interface:
Ethernet configuration interface 1 (X3)
Ethernet configuration interface 2 (X8)
To configure the connection between CODESYS programming software and Standard PLC of the
AC4S:
1 Preparations
►Connect CODESYS PC/laptop and configuration interface 1 (X3) or 2 (X8) of the device.
►Optional: Adjust IP settings of the Ethernet interfaces.
2 Select communication settings
►In the device tree: Double click on the [ifm_SmartPLC_SafeLine] symbol
►In the editor window: Click on [Communication Settings].
>The editor window shows the communication settings of the PLC.
3 Select gateway
►Select the requested gateway in the [Gateway] list.
>List shows selected gateway.
4 Set communication path
►Click on [Scan Network...]
>Window [Select Device] appears.
►Select the gateway node and click on [Scan network] to start the scan process.
>CODESYS scans network for devices.
>Window shows network path and detected devices.
►Select node of the AC4S.
>Information field shows detailed information about selected node.
►Click on [OK] to set the communication path to Standard PLC.
>CODESYS can transfer data to the Standard PLC of the AC4S.
