Communication Setting
Editor
Communication setting
(Underlined setting: default)
FB100/FB400/FB900
The communication parameters can be set using keys attached to the temperature controller. Be sure to match the settings to
those made under [Communication Setting] of the editor.
Communication protocol (engineering mode F60)
* The temperature controller must be set to “STOP” (control stop) before making settings.
Communication parameter (setup setting mode)
(Underlined setting: default)
Parameter changes will take effect when the temperature controller is turned off and on again or is switched from “STOP” to
“RUN”.
