A hours run counter can be created using the
counter function:
In this example the minutes are counted and are added up.
With the help of the division function one may do this also with hours
etc.
Using the IF condition with a trigger (e.g., digital input),
the hours run of an external device can be also counted.
Example hours run counter:
The process variable "RunCounterMinute" offers the minutes.
The process variable "RunCounterHour" offers the hours.
At first the process variable "RunCounterMinute" is defined which will contain the added up minutes later.
In addition, one may define a variable "RunCounterHour" which offers the counted hours after division by 60.
ProcessVars:
[<SetConfig _="PROCCFG" ver="y">
<ProcessVars>
<RunCounterMinute def="0"/>
<RunCounterHour>
<Value>
<LD _="/Process/PV/RunCounterMinute"/>
<LD _="60"/>
<DIV _=""/>
</Value>
</RunCounterHour>
</ProcessVars>
</SetConfig>]
As the next an Event is required which adds 1 to the process variable RunCounterMinute on each trigger.
EventHandler:
[<SetConfig _="EVENTS" ver="y">
<EventHandler>
<RunCount>
<Process>
<LD _="1"/>
<LD _="/Process/PV/RunCounterMinute"/>
<ADD _=""/>
<ST _="/Process/PV/RunCounterMinute"/>
</Process>
</RunCount>
</EventHandler>
</SetConfig>]
Then the "every minute" trigger of this event is defined using the scheduler.
Scheduler:
[<SetConfig _="SCHEDULE" ver="y">
<Schedule>
<RunCounter _="RunCount">
<Minute _="0-59"/>
</RunCounter>
</Schedule>
</SetConfig>]
Should the hours run of an external device be counted
(e.g., online signal using I/P0), so the EventHandler would have to be adapted ("IF" is available with firmware 2.0.2.). The variable RunCounterMinute becomes counted only if the input is 1.
[<SetConfig _="EVENTS" ver="y">
<EventHandler>
<RunCount>
<If _="/Process/MB/IO/I/P0">
<Process>
<LD _="1"/>
<LD _="/Process/PV/RunCounterMinute"/>
<ADD _=""/>
<ST _="/Process/PV/RunCounterMinute"/>
</Process>
</If>
</RunCount>
</EventHandler>
</SetConfig>]
