The first row in the figure shows that Contact Output 1 operation is being monitored. Its Modbus address is CAFA. The
actual value read from the device is 0, which means that it is off.
The second row in the figure shows the Contact Output 1 Name. It has a Modbus address of CAF0 and a default value of
"Cont Op 1." None of
Selection column settings render this value because they present the information based on
numbering systems.
