4.7.3OPC Server Example (Reading an analog input value)

The following is an example of reading analog values from an I-87017 inserted in slot 0 of an 8430/8830/8KE4/8KE8.

Step 1: Wire the8430/8830/8KE4/8KE8 and configure its network settings (IP, Mask, Gateway)

Step 2: Run the VxComm Utility to create a virtual COM port (e.g. COM3) to map the 8430/8830/8KE4/8KE8

Step 3: Run the DCON Utility to configure the I/O modules
