Hi,
I imported an old project created with version 3.51.20.50 into the new version 3.51.21.20. I'm using ModbusFB.ClientTCP v4.5.0.0. Strangely, I can no longer download the project due to a licensing issue I didn't have before. The number of Modbus channels has gone from 1 to 54!, and there's no license that would work.
Can anyone tell me where I'm going wrong?
Hi Sandro, did you find any solution?
I'm in version 3.5.20.40 and i have only one modbus channel.
I don't want the problem to happen to me if I do an update one day.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
The compiler detects one Modbus instance for each instance of the communication FB block. The example program above, although simple, reports 8 Modbus instances when compiled with the latest version.
Codesys Support says that you must use fieldbus I/O mapping, but this will result in the loss of the ability to programmatically modify communication parameters.

Hi Gatto,
Using version 3.5.21.xx, it is no longer possible to use Modbus function blocks (I make extensive use of these FBs.)as shown in the example.
