Support Questions / Writing to OPC server

« on: July 18, 2013, 06:46:06 AM »

Hello,

I've managed to read the values from the Matrikon OPC simulation, but when it comes to writing them, if I specify the address in a pushbutton's plcAddress, or tag nothing happens.

I have Tags configured in Matrikon Simulator, when I use the tag as input in the PLCAddress field, it works(Tag is "test_bit" as bucket brigade.boolean). But when I do the same with a button, to write a value/toggle/change, nothing happens?

If I do it with Omron CX server OPC, the server reports that it doesn't find the item.

Is there a different way to address when writing a value to a TAG on a OPC server?

Support Questions / Connecting with OPC driver

« on: July 14, 2013, 04:26:31 PM »

Hello,

 I've tryed to connect to a Omron CX-Server OPC with integrated drivers, in the driver properties field OPC server I've written "OpenDataServer.ODOPCServer", as the server presents itself. Others I've left unchanged . I have set up a test tag named bit_TEST which toggles true/false each second. When I connect with some third party OPC viewer, it connects and works, but if I compile AdvancedHMI, it gives me following errors:

"A first chance exception of type 'System.InvalidCastException' occurred in OpcNetApi.dll"
"A first chance exception of type 'Opc.NotConnectedException' occurred in OpcNetApi.dll"

I'm stuck here, please help, probably I've set up something wrong?
