2.1 General remarks
The module provides 4 IO-Link interfaces (ports) for integration into system CPX-E. The operating and load voltage
supply are implemented separately. LED indicators are available to display the operating status of the module and
connected devices. The address space provided to the IO-Link interfaces (ports) by the module is defined by DIL
switches.
Detailed information on the DIL switches can be found in the Detailed information on the DIL switches can
be found in the “Instructions for use of CPX-E-4IOL-…” è1.1 Further applicable documents.

2.2 IO-Link
The IO-Link communication system is used for the exchange of serial data from decentralised devices on the field
level. The connection type corresponds with a point-to-point connection, which means it can be connected to only
one device at every IO-Link interface.
The IO-Link interfaces (ports) can be operated in the following operating modes:
– Inactive (for unused ports)
– DI (the port acts like a digital input)
– IO-Link (IO-Link communication takes place at the port)
The module described in this document has IO-Link interfaces (ports) of Class B (Type B) that provides an
additional load voltage supply.
The devices description by IODD (IO Device Description) is not supported.

2.3 Diagnostics
For the diagnostics of errors, various possibilities are available:
– Internal system diagnostics
– LED indicators on the product
The internal system diagnostics is described in the “Description of the CPX-E system”
è1.1 Further applicable documents.
The LED indicators on the product are described in the following tables.

2.3.1 Diagnostic and error messages
Malfunctions or errors are sent to the bus module as an error number and can be evaluated by the network or
suitable software of Festo.
The prerequisite for sending diagnostic/error messages (if supported by the respective network) is an
existing connection to the host system and a corresponding parameterisation of the module
è3 Parameterisation.
2.3.2 Priorities of the diagnostic/error messages
The module differentiates various instances that can cause diagnostic/error messages. These instances have
various priorities in system CPX-E.
If several diagnostic/error messages cannot be sent in parallel on the network side, the error message with the
highest priority is displayed.
Priority Error instance Description
Highest System Error in the module
…
Port 1 Error in the module at port 1
Port 2 Error in the module at port 2
Port 3 Error in the module at port 3
Lowest Port 4 Error in the module at port 4
Tab. 2.8
– The error instances of the ports are allocated to the outputs by default.
– The prioritisation of the individual modules in system CPX-E runs to the right in descending order
from the bus module (position always a the far left).
– Diagnostic/error messages from inputs have priority over diagnostic/error messages from outputs.

The “Behaviour after SCS” parameter defines whether the voltage remains deactivated or reactivates automatically
after a short circuit or overload at the IO-Link interfaces (ports).
In case of the “Leave deactivated” setting, the voltage can be reactivated by deactivating and then reactivating the
“PS supply” parameter (èTab. 3.5). Otherwise the activation and deactivation of system CPX-E is required for the
return of voltage.
