Communication Setting
Editor
Communication setting
(Underlined setting: default)
Digital Indicating Controller
The communication parameters can be set using keys attached to the digital indicating controller.
Be sure to match the settings to those made under [Communication Setting] of the editor.
(Underlined setting: default)
* When changing parameters from the V series, set “LoCK (key lock): 4”.
Available Device Memory
The available setting range of device memory varies depending on the model. Be sure to set within the range available for the
model to be used. Use [TYPE] when assigning indirect device memory for macro programs.
Indirect Device Memory Designation
For the device memory address number, specify the value obtained by subtracting “1” from the actual address.
