Summary:
BLOCK and TIMEOUT parameters configured in the Citect.ini file for the [MODNET30] section will propagate these values in runtime for the MODNET protocol.

The Citect.ini shows only the [Modnet30] protocol parameter configured so that Citect is using the default [Modnet] protocol parameters.

[MODNET30]
 Block=128
 Timeout=3002

In Runtime the Kernel shows the following to suggest that both the Modnet and the Modnet30 protocol are showing the same Block and Timeout settings:


If the Citect.ini file is then modified to show the following additional [Modnet] section:

[MODNET30]
 Block=128
 Timeout=3002

[MODNET]
 Block=250
 Timeout=3004

Then you will see in the Kernel that the parameters for the [Modnet] section will propagate into the [Modnet30] protocol settings:

 

Solution:
This behavior is considered "By Design" and is currently not expected to be modified due to the way Citect recognizes any numeric appendage to the protocol name (IE Modnet20, Modnet30) as a modified version of the driver and not a separate instance.  

If you need to have your Modnet and Modnet30 protocols use different BLOCK and TIMEOUT settings during runtime, then please contact Citect Support for more information.
