I'm working on an existing system and I would like to read/write to some additional Powerflex parameters in the Studio5000 logic. My understanding, I can do this by configuring the datalinks. My question is, will this change the existing drive program itself (the way the drive itself has already been programmed). The drive was set up a while ago by someone else and it has been running fine and I don't want to change any internal drive programming. Does modifying the datalinks just change what the PLC sees? Thanks in advance
