[OPC Server for V570]

26 minutes ago, Flex727 said:

When I had this requirement, I purchased a UniStream USC-B5-B1 and used it as a gateway between the Vision PLC and the OPC client. The Unistream talked MODBUS TCP to the Vision PLC, collected all the data, then made it available to the OPC client. It was inexpensive and worked perfectly.

I also thought about it....

[OPC Server for V570]

Hello

I need a solution for opc server that can connect V570. I tried the UniOPC but it's an old version and no OPC client could connect to it. I tried Matrikon OPC Explorer and Dream Report OPC Client - both couldn't connect.

Is there a working OPC server I can use ?



Thank you

[Trend To SD]

Hi. I'm using the "Strt trnd ->SD" to write trend data to SD card.  I can see that the first time of writing and reading to/from the card is O.K and I can see the data on HMI. The file size on the sd is very small (5K) even the sample is every 1 min. and the process lasted for 3.5 hours.

At the second time, after few hours (my process is very long) after about 5 hours, when i stop saving to the card, the "In Progress (OFF at Stop Trend): Start Trend->SD" remains in 1, and when i try to read from the card i get the "Trend load error bit".

when i look in the SD with the SD manager, i see only the 1st Process trend and nothing from th 2nd process.

 

Please Advice.

[How to send more then 32 Byts in UniCan ?]

Sorry...

What I mean is:

what if I need to send diferent structure of collect and struct in some send commands ?

[How to send more then 32 Byts in UniCan ?]

But what if I nedd to send deferent data in somr srnd commands ? The structure must be the same in all Send commands....

[How to send more then 32 Byts in UniCan ?]

You're going to have to multiplex them. The easiest way I've found is to increment a pointer with a short timer and trigger different Send blocks tied to different pointer values. This way you don't have to keep track of block transfers on both ends.

I tried. You can't send more then 1 send block - bacause there is only 1 message arrived block at the other plc, and all data should matc.
