Daily Time Counter

[rapidscadaaks]

Hi

Please assist for configuring Rapid Scada in a way that one of the Channels records the cumulative time that another Chanel has been on a particular value or state. This Channel value should get reset everyday to 0.

For eg. Channel 101 records Status as 0 or 1 and this changes many times during the day. I need another Channel to record the number of minutes Channel 101 has been on Status 1 during a particular day.

Please help.

Many Thanks

Hi,

If the channel 101 changes not too often, you can measure it’s value every minute. If it’s 1, increase the channel 102. Does this method fit your needs?

Hi,
Thanks for your reply. I could definitely try this out; please let me know how to go about configuring Channel 102 to increase by 1 every minute if value is 1. Kindly also advise how to reset Channel 102 everyday to zero.

Many Thanks

Channel 101 is the source channel.
Channel 102 formula: EveryMin(() => IncIfOn(101, 103))
Channel 103 stores the cumulative value.
Channels 102 and 103 of the Calculated type.

Add to the Scripts table

public CnlData IncIfOn(int cnlNum1, int cnlNum2)
{
  if (Val(cnlNum1) > 0)
    SetData(cnlNum2, Val(cnlNum2) + 1, 1);
  return CnlData.Empty;
}

Note: the above is not tested.

Hi Mikhail

Many thanks for the solution. I have applied the solution as suggested and as of now it is working.

Please advise how to reset the value of Channel 103 to 0 everyday at say 6am or any other system time.

Thanks once again

Hi,

Option 1
Develop a function that calls the ResetChannels function (I’ve sent it to you) on a required time of a day.

Option 2
Use Automatic Control Module without programming. It can send a command on a certain time. A command will be sent to an input channel of the output type which has an output formula ResetChannels(101, 102), for example.

[Mikhail]

Option 1 looks better because it does not need an additional module.
Option 2 is easier.

Hi

Please guide for Option 2 for resetting Channel 1437 which is a Calculated Channel since I already have the additional module.

In the ACM, I can create a Time Trigger but need help for further steps i.e.

1. Do I need to make a new Input/Output Channel 1438 which has ResetChannels(1437) in Output Formula? All other fields i.e. Device, Tag, etc. will be empty

2. In the ACM what command to send to 1438?

Please do pardon me for my basic questions as this is quite new to me.

Looking forward to expeditious help.

Thanks

[Mikhail]

Hi,

You right.
1. Yes. An output channel.
2. Yes.
You should check how it works.

Hi Mikhail

Please let me know what Command should be sent by the ACM.

Thanks once again

[Mikhail]

Hi,
Any command to an output channel. When command is processed by a channel, the output formula is calculated to reset channels.

Many thanks. This works
