naresh_pt Posted January 18, 2006 Report Posted January 18, 2006 can anybody tell me , As we have to use TO/FROM instructions to data transfer between PLC & EJ71E71, is it possible to access PLC DATA using this ETHERNET. If yes please tell me the settings in "TRANSFER SETUP". Quote
panic mode Posted January 19, 2006 Report Posted January 19, 2006 yes, you can use TO/FROM to setup ethernet card and initiate data transfer between two plcs. For example you can READ (or write, or both...) block of data (D or M device or whatever) from another plc on a network. this will likely be quite challenging if you do it on your own, specially if you have no experience with ethernet and programming of mitsubishi comm cards. read this: http://forums.mrplc.com/index.php?showtopic=6090 note that third reply has sample code that sends unsolicited message (block of data registers) to another plc. (well it was PC with driver simulating another PLC). Quote
