Summary:

When using the device SIXNET EtherTRAK-2 (fairly new IO modules), communication can be achieved by using the SXDIRECT driver. When the device is offline in runtime (in the test, it is purposely disconnected), the expected #COM is present. However, when the device is then being put online again, Citect seems not having the ability to regain the connection to the IODevice. 

Solution:

Modify the driver specific .ini parameter [SXDIRECT] ChannelOffline = 1

This will change the initialisation method of the IO modules to be channel initialisation based instead of device initialisation (more details in the driver specification document).
