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. 


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).
