VIEWING INPUT AND HOLDING REGISTERS

Figure 7-22. Holding and Input Registers can be viewed in RRM.

Measured data is continuously stored in the Input Registers. Viewing the contents of the Input Registers, advanced users can check that the transmitter works properly.

The Holding Registers store various transmitter parameters, such as configuration data, used to control the measurement performance.

Using RRM, most Holding Registers can be edited by simply typing a new value in the appropriate Value input field. Some Holding Registers can be edited in a separate window. In this case, you can change individual data bits.

To be able to view the Input/Holding registers in RRM, the Service Mode must be activated:

1.Choose the Enter Service Mode option from the Service menu.

2.Type the password (default password is “admin”). Now the View Input and View Holding Registers options are available.

3.Choose the View Input/Holding Registers option from the Service menu.

4.Click the Read button. To change a Holding register value, just type a new value in the corresponding Value field. The new value is not stored until the Store button is clicked.
