Event History
General Description
The event history registers describe the last 100 encountered events. The event history format corresponds to a series of 100 records. Each record is composed of 5 registers describing one event.
A read request of 5x(n) registers is necessary to read the last n event records, where 5 is the number of registers for each event record.
For example, a read request of 5x3 = 15 registers is necessary to read the last 3 event records of the event history:
-
The first five registers describe the first event record (most recent event).
-
The next five registers describe the second event record.
-
The last five registers describe the third event record.
There are two event histories, 1 per IO module.

Event Record
A block request of five registers is necessary to read an event record.The order and the description of the event record registers of IO 2 are the same as those of IO 1:

Alarm Definition
Alarms are specific events that need to be reset.
The reset mode of an alarm can be:
-
automatic: the alarm is reset automatically when the alarm is no more active.
-
manual: the alarm is reset manually with the Test/Reset pushbutton located on the front face of the IO module and when the alarm is no more active.
-
remote: the alarm is reset remotely with the Reset command sent via the communication and when the alarm is no more active.
Each alarm has a priority level that manages the alarm display on the FDM121 display:
-
no priority = N/A (not affected)
-
low priority = 1. No alarm display on the FDM121 display
-
medium priority = 2. The FDM121 display LED is steady ON.
-
high priority = 3. The FDM121 display LED blinks and a pop-up screen informs that the alarm has occurred.
