Thank for Program but it Difficult to understand for me, please give a simple example of using PMCR to read data from node 1 of port 0 of the device at address 6001 (floating). Thank you.

There is a full description in the Word document in the file. You have to download the file to the card and then set up the PMCR function in CX-P to read from the device. There is also a spreadsheet so that you can get the right address for the PMCR command. I really cannot help you further as the devices we all read from are all different, so are the addresses and the information we receive back from different devices. There are also samples in the Word document. Edited 23 Dec 2011 by BobB
