4.26.5.9.3 General module properties
The module has the option of supplying power to IO-Link devices.
To prevent damage to hardware, each channel is monitored individually and equipped with its own overload pro-
tection. In this way, an overload in the power supply on one channel does not affect the other channels.
4.26.5.9.3.1 Configuring overload protection for the IO-Link supply
Name:
CfO_SupplyConfig
This register can be used to define how the module supply behaves for all channels when an overload occurs.
The following rules apply:
•
The overload duration (bits 6-7) corresponds to the time that the supply remains switched on after an
overload is detected. The supply is only cut off if the overcurrent occurs for the entire time configured.
•
The switch-off duration (bits 4-5) corresponds to the time that the supply remains switched off after a
overload-related cutoff until it is switched back on.
For this reason, an overload that occurs over a longer period can cause the module supply to cyclically
switch on/off.

4.26.5.9.3.2 OperatingMode
Name:
CfO_OperatingMode01 to CfO_OperatingMode04
This register is the same as the first bytes of the ChannelMode register in the IO-Link configuration.
It can be used to switch a channel's mode at runtime. The rest of the settings for the ChannelMode register are
unchanged and continue to be used in the selected mode.
