Operation features
The operation process of the GENBI function is divided into an acquisition part and a
suppression part.
(i)
Signal acquisition process
The acquisition process checks for the occurrence of state changes in each BI circuit. If a state
change is detected, the acquisition process determines the direction of the state change and
observes the time that the state change occurred.
The user needs to apply a signal as a setting so that signal acquisition will be carried out.
Figure 4.10-1 outlines the settings when BI1 circuits at IO#1 are considered. For example,
when a signal is received at BI1, the GENBI function can acquire the signal when the user has
set
200B001 8001001110
† for the setting [
SLOT1 GB01-SG
]. After acquisition, the GENBI
function generates “SLOT1 GBI01_STATE (580001 0010001001)” signal in Boolean form; it
consists of “time stamp information” and “quality information”.

†Note: The BI1 (200B001 8001001110) is used purely by way of explanation; the user can
select either BI1-NC, BI1, or BI1-CPL so that the GENBI function acquire the
received signal. For more information of the signal acquisition points and the
meaning of the BI logic, see chapter
Technical description: Binary IO module.
(ii)
Event suppression process
When the signal switches between the “On” and “Off” state frequently over a short period of
time, the GENBI function will receive these repetitive signals. When these repetitive signals
are converted into event information, repetitive events are issued on occurrence of the
repetitive signals. The event suppression function is provided to suppress event appearance
