Summary:
I would like to customise the Long format returned by Citect's MBSLAVE driver.  

When I poll Citect's Modbus slave, the Long data type is implemented with the following formula: 10000 x low register + high register .

Is this customisable?


Solution:

The MBSLAVE driver has been enhanced, and version 2.01.01.001has now a LongDataType parameter, similar to the LongDataType parameter for the Modbus driver.

You can therefore now customise the Long implementation, and have a choice between teh following formulae:

Allowable Values      0 to 3, where:

    0 = 10000 x low register + high register

    1 = 65536 x low register + high register

    2 = 10000 x high register + low register

    3 = 65536 x high register + low register
