Problem with OPC tag

Hi Kevin，

I got a problem that Byte in Siemens PLC is unsigned, however in Ignition, the opc tag will be showed in Int1, so the value greater than 128 will be error.
Any ideas?

In Tag Editor define Data Type as Short and Source Data Type as Byte and… voila… you have tag from 0 to 255.

Hi zxcslo,
Thanks, that works.
