Parameter Communication operation and setting
FR-E700 SC EC/ENE 6 - 235
Operation selection at communication error occurrence (Pr. 121, Pr. 122, PR. 349, Pr. 501, Pr. 502)
The above parameters can be set for the FR-E700 SC EC when Pr. 160 "User group read selection" = 0.
However, it can be set any time when the communication option is connected. (Refer to section
6.17.4.)
햲
This setting is only available for the FR-E700 SC ENE.
