Error Invalid Station Setting Function - Mitsubishi Electric MELSEC-Q Series User Manual

Error invalid station setting function

Even if a data link error occurs in a slave station, the station is not detected as a faulty station in the master station and
local station. This function is used when a slave station is powered off as a matter of the system configuration or for
other purposes.
Note, however, that an error is not detected in an error invalid station. Because the error invalid station setting is
configured in the network parameter, the setting cannot be changed during data link. To change the setting during data
link, use the temporary error invalid station setting function. (
