Can the 6K* be directly interfaced to I/O devices like Grayhill and Opto22 via Ethernet?
With the release of 6K operating system 5.3, which features the Ethernet client capability, the 6K can interface with OPTO22 SNAP I/O through Modbus/TCP. Additions to the 6K command language allow the 6K to establish a connection, set outputs, and read both inputs and outputs.
Currently, the 6K cannot be interfaced with Grayhill devices.
