  1. I think that will do nicely. Joe T.

  2. In UnitronicsLand, physical placement does not guarantee scan sequence. It's what the compiler decides to do, which is not always predictable. Right-click on the left side of the network and select STL Quick View to look at the compiled code sequence. You should be able to figure it out and this is how the network logic will solve. If you're worried about this I would break the logic into more than one network. Joe T.

  3. 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

  4. 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 yo

  5. Oops, forgot a step. Need to do the Store Timer/Counter Preset after the addition.

  6. You seem to be mixing up contact and coils. Also in your second ladder rung you have two separate logic threads. Do not do that. Further, that second logic thread is screwing everything else up - you are forcing MB 3, O 2, and TD 1 on all the time. I would do that part this way: This is not clear to me. It looks like you've left out a step as you state that the first valve closes then you immediately say it opens again.

  7. Hello, I can solve my problem setting the G120 parameteres like the information of the table (parameteres marked in yellow) Best regards! Mario

  8. Hello, The observed delay is due to the fact that DTI file is now digitally signed. Starting from next UniLogic version (1.31), the "Store DTI to file" will include a new input controlling whether or not the file should be signed, which will give you a way to suppress that delay. Have a good day!

  9. Hi, When use mechanical switch, then it's contact(s) "bounce" when fast change it's position. Normal Digital Input has internal filter, which "neutralize" contact(s) bouncing.HSI has no such filters. You can use button on PLC display to start timer and generate fixed length output pulse. Use this pulse as input for high speed counter. Then everything should work as supposed. B.R.

  10. What is the I/O module the encoder is connected to? Typically on a V570 you use a Snap IO module which allows some of the inputs to be configured as encoder type. These are automatically high speed and take care of the rising and falling edges for you. Joe T.
