![]() This would not be the cheapest in terms of capital cost though. And you can see here that NI's Industrial Automation OPC Server's do include an object for GE Fanuc Versamax via Ethernet. If you don't really need to limit yourself to using VISA, there are ActiveX and OPC drivers available which use SNP/SNPX that you can find with a web search. ![]() The SNP/SNPX protocol is/was well documented in a GE FANUC manual which you could get from them (in 1993 it was GFK-052B "Series 90 PLC Serial Communications User's Manual") so you still can write your own set of VIs. With a web search you might find something (I almost programmed one 10 years ago). Your options are similar to those for Modbus, except that I'm not aware of any existing free set of LabVIEW VI's for it. You might have to modify some of the free LabVIEW Modbus VIs to suit you needs, but they are useful as examples if you have little experience programming a serial driver. If you really want to limit yourself to the option of using VISA, then it's Items 1. ![]() The link here is a good outline of the different options available. GE Fanuc Proficy VersaMax PLC Trainer - PLC Training Kit The software is not included with this kit, you will need Proficy Machine Edition Includes: 1 PLC (IC200NDR001), 1 Training Module with 4 discrete inputs and 4 discrete outputs. ![]() There may be variations between models, but I believe all VersaMax support Modbus and GE's own SNP/SNPX serial communication protocols. How can i access data acquired by PLC and how can i connect it with labview using VISA? I dont have any other data acquisition devices other than PLC. ![]()
