Description of Features 4-17
1503-UM054C-EN-P – June 2013
“Master” Counter
The Master counter will include all operations, since initial use of the
IntelliVAC Plus product.
Each operation refers to the completion of a ‘Close’ operation. If a
close command is initiated but the contactor does not close (i.e. due
to an under-voltage condition) then the count will not be
incremented.
A Master Counter shall be provided for each of the IntelliVAC MC
units in an MC configuration.
The Master Counter parameters will be viewable, for each of the five
(5) IB units, on DeviceNet in the following manner:
‘IB1 Master Counter = ‘ ‘0’ to ‘16777215’ (24 bit counter)
‘IB2 Master Counter = ‘ ‘0’ to ‘16777215’ (24 bit counter)
‘IB3 Master Counter = ‘ ‘0’ to ‘16777215’ (24 bit counter)
‘IB4 Master Counter = ‘ ‘0’ to ‘16777215’ (24 bit counter)
‘IB5 Master Counter = ‘ ‘0’ to ‘16777215’ (24 bit counter)
This parameter will default to 0 for a new IntelliVAC Plus product
and cannot be reset.
“Operations Since” Counter
The Operations Since counter will include all operations since a
register reset has occurred, associated with a date/time set by the
real-time clock. Settings are provided for three (3) values: the most
current and the previous two.
This counter will keep track of all ‘Close’ operations since a new
unit has been powered up or since it was last reset. A date/time will
be associated with the start of implementation of this counter. Once
the RTC has been adjusted, this counter should be reset to have it
begin counting from a realistic date/time. Once a register reset has
been implemented, the previous date/time and count value will be
copied into a set of registers. This will occur for one more cycle,
after another register reset has been implemented, so that there will
always be a history of the most current “operations since” counter,
along with its reset time and for two previous “operations since”
counters, along with their reset times.
An Operations Counter will be reset in the following manner-data
will be available, for each of the five (5) IB units, on DeviceNet in
the following manner:
‘IB1 Reset Ops Since Counter’ (present ‘IB1 Ops Since 0
data/time’ saved to ‘IB1 Ops Since 1’ along with counter value
and ‘IB1 Ops Since 1 data/time’ saved to ‘IB1 Ops Since 2’
along with counter value) with ‘IB1 Ops Since0’ counter = ‘0’
