Notes on ifm system solutions
12229
With the AC142n, ifm electronic offers different system solutions for the simple implementation of
typical applications. System solutions consist of applications which are processed by the
device-internal CODESYS PLC.
ifm system solutions and user-created applications must not be stored and run simultaneously
on the AC142n!
► Delete all CODESYS system solutions stored on the device before installing new ifm
system solutions or user applications!
ifm system solutions can only be installed and run if the device-internal PLC is activated.
► Activate the PLC of the AC142n (→
Enable/Disable the device-internal PLC
(
))!
Users can download the available ifm system solutions from ifm's website.

Types of ifm system solutions
8682
There are 2 types of ifm system solutions:
Single apps
Single apps provide the user with a
CODESYS-based solution. Single apps directly
access the I/O mechanisms of the CODESYS
PLC. Only one single app must be stored and
executed on the device.
Basic app + multi apps
Multi apps provide the user with the possibility to
execute different CODESYS-based solutions in
parallel. The multi apps use the services of the
basic app in order to be able to access the inputs
and outputs of AC142n at the same time. They
operate as a pure communication layer between
the I/O mechanisms of the CODESYS PLC and
the connected multi apps.
Maximum 5 multi apps at a time can be stored
and executed in parallel on the device.
