Hello all. In vision I created a simple DST add subtract and put a button on the screen. Attached picture. Is there any way of doing this in unistream? I can't seem to get it to work. Many thanks, Steve -
Maybe fastest way to build this type of application is using FB Drum sequencer. Please read help topic about this FB and try to run this idea in Samba. Simple place checkbox for needed MB and run outputs via this MB. Please open Drum example projects in visilogic Help menu - you can easly implement one of them for your hardware. -
Further to Kratmel's good advice, it is worth saying that many modbus things will not communicate to Visions at greater than 9600. It is always worth starting slowly and trying bigger baud rates after getting things working ok in the first place. I also note you have 2 stop bits. ?? I'd also make your timeout bigger, along the lines of the previous baud rate comment but in this case it is start big and reduce. Why, and how, are you working MB107? cheers, Aus -
HI, Please send your request to support@unitronicvs.com B.R. -
Hi, try this checklist: - wire swap A & B; - check - is it V700 and Energy Analyzer correct in master-slave mode; - configure com port and disable all modbus send net. Connect V700 A&B wires to PC - Energy Analyzer RS485net. Go to info mode and try monitor RS485 packets via V700 com port. If you see something correct than port and speed connection is OK. - try to activate Modbus and check via Info mode - what is go from V700 and from Energy Analyzer; - try to use single Modbus command activated by button and check Modbus status. As i see you try to read MF 44 direct via modbus. On forum is present topics with Energy Meters float read via Modbus issue - maybe in your case some tips and tricks with two MI to MF convertion needed. Please post Energy Analyzer model.
