Hello Rahul; To read/write parameters on your MasterDrive you will need access to thw PKW (parameter values) area, using PPO1, PPO2 or PPO5. This PKW is refered to as "Parameter identification zone" in the attached illustration Since the issue has already beendiscusseda few times on the site, here are a few ideas written down elsewhere that could help you out: PKW (parameter block words) This is a group of 4 words used to read/write parameters in the drive. They are not available in PPO2 and PPO3 (you chose these if you do not want to change parameters on the fly). Generally you set parameters on the keypad of the drive, or with a program like DriveMonitor, Starter... during commissioning. Often you never change them during operation; but if your application requires tweeking of the drive parameters while in run, you will use this area to do so. So you will select PPO1,4 or 5 in your hardware configuration. This section of 4 words has a peculiarity that is different from the PZD: it is actually a terlegram that you must fill with data, and transfer as a single block to the drive: you cannot write each word individually to the drive, it will not recognize it as a valid read/write. You have to fill in all the words (such as Write request bit, Parameter number, sub-index number and parameter value to be written) then transfer the 4 words in a single write operation. Since Siemens PLCs cannot read/write more than 2 words in a single operation (the size of a DINT or REAL variable) this requires special FCs, SFC14 and SFC 15. MASTERDRIVES have functionality of reading and writing parameters with a PKW address area. The mechanism is described in a compendium manual Section 8.2.3 "Mechanisms for processing parameters via the Profibus". http://support.automation.siemens.com/US/view/en/23660019 Hope this helps, Daniel Chartier |
