7 Setting and procedure for operation
7.7.3 Initial setting
This section explains the setting of the operating condition for phase wire system, primary voltage,
primary current, current demand time, and voltage demand time, primary voltage of VT, secondary
voltage of VT, primary current of CT that are required for measurement. Once each value is set,
these values will be stored in the nonvolatile memory of the module, so that reconfiguration is not
needed. You can also perform the setting using sequence program. In this case, you need to create
a program, as referring to Chapter 8.
Follow the procedure below for each setting.
(1) Check the current setting
(2) Set the Buffer memory
(1) Check the current setting
1) From the "Online" menu, select "Monitor" – "Buffer memory batch ...". The dialog box to
monitor all buffer memories. After setting the address as shown below, click the
Start monitoring button to check the current buffer memory status.
Module initial address:
Buffer memory address:
(Display: 16-bit integer, numerical value: check the number in decimal)
2) Check each item. The following shows items for operating condition settings. For specific
setting value, see the provided references.
