Hello S7Mgr; You are recieving good help and pointers from the forum, but you are still confusing us as to what ypu want to do: 3964R is a protocol (a procedure, actually, in Siemens' terms) that is available directly on the PtP CPs (CP 340/341, for example). You have simply to select it in the parametrization software for the CP 341, configure it and use the standard functions FC7/FC8 to exchange data with your comm partner (wish it was all that easy, there is some work fir you to do!): Example FAQ on setting up 3964R with CP 340 with sample project(same procedure with CP 341) http://support.automation.siemens.com/WW/view/en/1766265 A loadable driver for PtP CPs is a driver that is not available on the basic CP 341, and that yopu have to buy from Siemens; Modbus is one of them. Here is a list of different drivers, lodable and native, you can use with the CP 341: Available drivers for CP 341: http://support.automation.siemens.com/WW/view/en/378923 |
