(2) Precautions
(a) Precautions when temporary error invalid station setting is executed
• Do not write to buffer memory addresses 5E0
• Do not execute at one time by programs and other peripherals.
If executed at one time, temporary error invalid station setting may not operate normally.
(b) Input/output status at temporary error invalid station setting
All the cyclic transmission data of the stations set as temporary error-invalid stations is refreshed.
However, when a station set as a temporary error-invalid station becomes faulty, the input is retained and the
output switches off.
(c) When multiple stations are set as occupied stations, the temporary error invalid
station setting must be executed specifying the starting station number for each
occupied station. If executing temporary error invalid station setting to a station
which is not the starting station in the actual assignment, the invalid setting is
ignored.
