(2) Event output function (Only for H-DO-C type)
The event output function enables up to eight points to be output per module of unique alarms
different from ordinary temperature and AI alarms, control unit operations and comparison results
which are output only under certain conditions.
The function can be set for each channel of the H-DO-C module.
Extension alarm output function
An extension alarm is output independently of H-TIO module alarms.
As it is independently set, it can be provided as a dedicated alarm output.

Extension alarm output is different from the ordinary alarm output from the H-DO-A/B type
module. Similarly, the ordinary alarm cannot be output from the H-DO-C type module (for
event output).
The alarm differential gap and alarm delay timer are commonly set.
H-DO-C module (event output function) and the H-PCP module with the specification of
ladder communication cannot be selected at the same time.
Each alarm can be assigned from the dedicated host computer via communication.
For details on alarm selection, refer to SR Mini/SR Mini HG SYSTEM Supplementary
Information Initialize Settings [Extended Communications] (IMSRM07-E
).
