Word (Other than Comms control word, comms reference word) transfer between S7-300 & AC30 over profibus

Ravi Prabhat
By 

I need to send a Word (other than comms control word & comms reference word) from my S7-300 PLC to AC30 drive over profibus & then use it bit by bit in PDQ. Which parameter should I select in Read mapping? Similarly, I need to convert a set of bits to Word in PDQ and then send it to the PLC. Which parameter should be linked to write mapping.

    Hi Ravi,

    please see on your local system the PDQ manual folder:

    C:\Program Files (x86)\Parker Hannifin Manufacturing Ltd\PDQ\3S CoDeSys\QuickTool\AppManuals

    Manual HA503559_0B.PDF on page 51.. shows how to add a custom parameter.

    1st: Go to Tools -->  Drive Customization --> Edit --> New Soft Parameter

    2nd: Put in your custom parameter with name, value type …  in the EditParameterCW

    3rd: Create a global variable value and map it (Browse) in the EditParameterCW

    4th: Connect your new values to the WORD_AS_BIT, BIT_AS_WORD conversion functions
