Check before connecting

Check the device brand, model, driver version and interface. Use the wiring diagram to confirm terminals and port assignments.
Prepare a point list with addresses or objects, data types, byte order, units and read/write permissions.
Confirm the role at each end and the device address, serial settings, or IP address and port.
Check point count, device count and physical port count separately, then confirm capacity for the actual data volume.

How to choose within a series

Match device-side protocols and the host system first, then check ports, wireless connections and capacity. Candidates below use confirmed model specifications.

Current model groupHMI1004

You need multiple serial and Ethernet protocols

Check models confirmed to cover all acquisition protocols for serial and Ethernet connections. Check protocol scope and physical port counts separately. Confirm dedicated CAN, KNX TP and 2-wire MBus connections for the specific model.
