text: <s>[INST] PowerFlex 40 via Ethernet Hi all. I'm developing a project with several PowerFlex 700 VC's and PowerFlex 40's on Ethernet to a ControlLogix. I'm having to set up datalinks to get a couple of extra parameters read back in. The 700s seemed pretty simple. But on the 40's I can't find where to add the extra datalinks. The Data Format box (in Module Definition) is set to 0 Data Links and is grayed out, so I can't change it. I've looked in the user manuals for the 40 and the 22-Comm-E module and I can't seem to find the info I need. [/INST] Unfortunately, Powerflex 4x has not the possibility to use Datalinks... :smileysad: Only way you have in order to read/write parameter is through Explicit Messaging.
