Figure 217: Sequence Of Events Recorder Trigger Logic
The first level of the Event Logic consists of an "AND" gate and an "OR" gate which uses
the trigger parameters in
Table 54 as inputs. The output of the "AND" and "OR" gates are
passed to a logic gate that is user selectable as either an "AND" or "OR" gate. When the
logic is true, it triggers the Sequence of Events Recorder.
The event will be recorded in volatile SDRAM and transferred to non-volatile flash
memory every four cycles. There is a possibility that events can be lost in cases where the
control loses power in the middle of a storage cycle.
5.3.1 Setting up the sequence of events recorder
Pickup or Dropout for each trigger parameter may be selected to trigger the Sequence of
Events Recorder.
Communication must be established with the target control for this
procedure. When not connected to the control, the Save selection does not
save the Sequence of Event settings to the open file.
1. From the TCC600® Main Screen menu select Setup/Sequence of Events/Setup .
TCC600 will display the Sequence of Events Setup dialog screen.
