Machine uptime and downtime tracking

jtashaffer · May 20, 2015

I am using studio 5000 and Compactlogix controllers. I am wanting to track uptime and downtime on 3 different machines. It is setup already but it is done using GSV instructions. There seems to be issues with the setup and doesn't appear to be accurate. I want to try to setup it with out using this GSV instructions and use timers. The original setup was done by a outside source. How do you guys track uptime and downtime accurately.

Why do you think timers would be better than the real time clock?

What increment of time are you looking to base your U/D time on?

2-12hr shifts (24hrs). Uptime and downtime per 12 shift. As far as the GSV instructions the processor is getting minor error from this setup. I want to have a setup more simplified to track uptime and downtime and see if I can stop the processor minor errors.

We also have two 12 hour shifts. I use two retentive timer with a 60000 preset time. On completion it increments an uptime/downtime minutes counter. Very simple and allows me to view/edit the info if needed.

I use the information to send out shift reports to the managers. The runtime + downtime minutes is 718 minutes (2 minutes short of 12 hours) due to the timers not completing. It's a general report and doesn't need to be more accurate than that.

Jtashaffer:
I do the same here, I do not count seconds only minutes.
But i'm curious, when you say minor errors your mean seconds or minutes.
There is a routine from rockwell that counts elapsed time, That can be useful for you.
There's even and AOI:

Lessthanthree do you have example of your program?

LessThanThree · May 20, 2015

Only have a minute until lunch is over so I just wrote out the ladder logic. In studio 5000 just copy paste the below lines and define the variables.

downtime:
BST XIO Machine_is_Running RTO downtime_timer 60000 0 NXB XIC downtime_timer.DN ADD downtime_min 1 downtime_min RES downtime_timer BND

uptime:
BST XIC Machine_is_Running RTO uptime_timer 60000 0 NXB XIC uptime_timer.DN ADD uptime_min 1 uptime_min RES uptime_timer BND

ok thanks lessthanthree

Lessthanthree:
I like your approach.

Does anyone have any programming examples for the uptime and downtime in RS 5000

jtashaffer · May 21, 2015

I want to see if anyone has other ways if doing it besides LessThanThree

jtashaffer · May 21, 2015

??? No one tracks uptime and downtime

widelto · May 21, 2015

Jtashaffer:
I have an example is Rslogix 500.
Is that suitable for you ??

jtashaffer · May 21, 2015

Yeah I can always convert it
