IO-Link master
28
Byte 0 (COM control) can be used to temporarily (as long as the corresponding COM control bit
is set) switch one or more IO-Link ports previously configured in the digital input mode (DI) to the
IO-Link mode� Cyclic and acyclic communication can therefore be established with the connected
IO-Link device�
DO state on pin 4 (C/Q)
The digital output on the corresponding port can be controlled via process data� The I/O-Link port
must be set beforehand to function in the DO mode�
Start-up parameters
The status/control module in slot 1 contains the following start-up parameters
which refer to the runtime behaviour of the entire device�
Parameter
Possible values
Description
Port synchronisation
Port synchronisation
0 = free (def)
Synchronisation of the ports
running in the IO-Link mode
Diagnostic settings
Channel-related diagnostics
0 = deactivated
1 = activated (def)
The channel-related diagnostics
can be deactivated/activated�
Extended channel-related
diagnostics
0 = deactivated
1 = activated (def)
The extended channel-related
diagnostics can be deactivated /
activated�
Diagnostics IOLM status
0 = deactivated
1 = activated (def)
The diagnostics of the IO-Link
master can be deactivated /
activated
Diagnostics IOLD port 1 ���
Diagnostics IOLD port 8
0 = deactivated
1 = activated (def)
For each IO-Link port the IO-Link
diagnostics can be separately
deactivated/activated�
If activated, the IO-Link
events of the IO-Link device
are acknowledged on the
respective port and mapped to
the PROFIBUS diagnostics�If
deactivated, the events are only
acknowledged�
Substitute values
Behaviour in the event of error for
status / control module
0 = clear all (def)
1 = set all
2 = hold last value
3 = substitute value
Substitute value behaviour for
the IO-Link ports in the DO mode
(pin 4)�
