2 Function
2.1 General
The module provides four IO-Link interfaces (ports) for integration into an automation 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 by the module to the IO-Link interfaces (ports) is defined by DIL switches.

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 (port).
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 provide
an additional load voltage supply.
The devices description by IODD (IO Device Description) is not supported.

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 net-
work or suitable Festo software.
The prerequisite for sending diagnostic/error messages (if supported by the network) is an existing
connection to the host system and a corresponding parameterisation of the module
è 3 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 the automation 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. 12 Priorities of the diagnostic/error messages
• The error instances of the ports are allocated to the outputs by default.
• The prioritisation of the individual modules in the automation system CPX-E runs to the right in
descending order from the bus module (position always far left).
• Diagnostic/error messages from inputs have priority over diagnostic/error messages from out-
puts.

Function
13Festo — CPX-E-4IOL-... — 2020-01a

When accessing the module through the software, the relevant current error can be determined more
precisely for each port using an event code if the error is returned to the connected device
è 2.3.4 Event codes.
2.3.4 Event codes
Within the communication between module and device, so-called events are used for status dia-
gnostics, which include an error code (event code), each with a constant length of 2bytes.

3.2.1 Monitoring Uload
The "Monitoring Uload" parameter defines whether the monitoring of the load voltage supply shall be

on the module.

3.2.2 Behaviour after SCS
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).
The voltage can be switched on again with the "leave switched off" setting by deactivating and then
reactivating the "PS supply" (è Tab. 19) parameter. Otherwise the activation and deactivation of the
automation system CPX-E is required to restore the voltage.

3.2.5 Cycle time (Port 1… 4)
The "Cycle time" parameter defines the cycle time (low/high) set by the IO-Link master.
The setting can be made separately for each IO-Link interface (port).
The value becomes effective at the start of the IO-Link connection by setting the "Operating mode"
parameter to "IO-Link" (è Tab. 22). Changes during IO-Link operation are not made until the connec-
tion has been deactivated and then reactivated again.
