Event Recording
The events are recorded with the 1 ms resolution time-tag when the status changes. The user can
set the maximum 128 recording items and their status change mode by RSM100. The event
recording is initiated by PLC function. The event item and name is set by RSM100. The event
items can be assigned to a signal number in the signal list. The status change mode is set to "On"
(only recording when On.) or "On/Off"(recording when both On and Off.) mode by setting. The
items of "On/Off" mode are specified by "Bi-trigger events" setting. If the "Bi-trigger events" is
set to "100", No.1 to 100 events are "On/Off" mode and No.101 to 128 events are "On" mode.
The elements necessary for event recording and their setting ranges are shown in the table below.

Bi-trigger events
EVENT1 – EVENT128
Up to 480 records can be stored. If an additional event occurs when 480 records have been stored,
the oldest event record is deleted and the latest event record is then stored.
3.4.4
Disturbance Recording
Disturbance recording is started when a start command by PLC is initiated. User can configure
eight disturbance record triggers (Signal No.:2632 to 2639) by PLC editor, and can set them "use
(=ON)" or "no use (=OFF)" respectively, as shown in Figure 3.4.1. OC, EF, SEF, NOC, OV, UV,
ZOV, and NOV elements are provided as a starter element. The signal number of desired starting
element is connected to the disturbance record trigger by PLC function.
