Commissioning for PROFINET
•
Hold Last:
The last valid output value received by the control unit is continuously and cyclically trans-
ferred to the IO-Link device.
•
Replacement Value:
If this option is selected, you can enter a substitute value in the following input fields,
which will be continuously and cyclically transmitted to the IO-Link device.
•
IO-Link master command:
The "IO-Link master command" option enables the use of IO-Link-specific mechanisms
for valid/invalid output process data.
In this way, the behavior is determined by the device itself.

Port Parameters in IO-Link Mode
Enable Port Diagnosis
Enable or disable the IO-Link master port diagnosis and the IO-Link device alarms using the
"Enable Port Diagnosis" option. This affects the diagnosis only in relation to the IO-Link chan-
nel (pin 4) of the IO port.
Default: Enabled
Enable Process Alarm (Device Notifications)
Enable or disable the IO-Link device alarm notifications using the "Enable Process Alarm"
option. When this option is disabled, all "Notification" IO-Link device alarms are suppressed in
the IO-Link master.
Default: Enabled
Configuration Source
•
PROFINET IO controller
The PROFINET IO controller assigns the IO-Link master port configuration.
•
Port and device configuration tool
(not yet supported)
An external IO-Link port and IO-Link device configuration tool assigns the IO-Link master
port configuration.
Default: PROFINET IO controller
Enable Input Fraction
If the user configures a subslot module with less than the actual input data of the device, the IO-
Link master sends as many IO-Link device input bytes as possible to the PLC, including the
PQI byte of the subslot module. Consequently, only "0" up to (device input length - 1) octets of
the input data of the device are mapped to the PROFINET process input data of the IO-Link
master
If this option is disabled and the input data length does not match, a data length mismatch
alarm is enabled. If a mismatch is detected in the output data, a diagnosis of the process data
"mismatches" is generated regardless of the selected "Enable Input Fraction" setting.
Enable Pull/Plug
Enable or disable the pull/plug alarms of an IOL device (add/remove submodules) using the
"Enable Pull/Plug" option. The failure or return of an IO-Link device is mapped via PROFINET
pull/plug alarms. This assignment is independent of the switch-on and shutdown phases.
•
Plug alarms
•
Ready to operate
: IOL device is ready
•
COM fault
: wrong device or other problems
•
IOL device started but not ready for operation due to a fault
