Recorded capacity

Capacity to confirm

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.
