PCOM over Ethernet is not working!

Recommended Posts

1. Firstly - I checked a PCOM over RS485 using the objects of "uncomdriv.dll" to perform several read/write operations from my software app and it was

succesfully.

2. Secondly - I checked a PCOM over ETHERNET using a REMOTE ACCESS utility and it was succesfully.

3. Finally - I checked a PCOM over ETHERNET using the objects of "uncomdriv.dll" to perform several read/write operations from my software app and it

was not working

Pls, Your help with a sequence of operations/definitions required to initialize the PC/PLC to implement the PCOM functions.as described at 3 above.

regards

david a.

Dear David,

Did you see that you've to add an header before your PCOM message when using Ethernet ?

(last page of the PCOM documentation)
