RSView Studio logic questions

Hey guys, I have a PV+700 connected dH+ to a PLC5. This is also connected to our company network via ethernet. I have been requested to track machine runtime and # of cycles and have this broken down into 1 hour segments. I did this with a couple of counters in the PLC which is reset at the top of every hour. The data is then moved into two registers where a PV tag is assigned to them. My thinking was that we could poll the PV+ and time stamp the data once an hour and store it to a database. Done this way, all the actual computations and counting would be done in the PLC. This is my preference, but I have an engineer who wants to do all this in the PV+. I have never done this, and I am not even sure how or if I can write a VB script in RSView studio to do this, and what is the general consensus on where these calculations are done most of the time? Any input is appreciated.

Russ:

I would vote for performing the calculations in the PLC for a couple of reasons:

1. RSView ME does not support VBA on the PanelView Plus. You would need RSView32 or RSView SE for this functionality.

2. Even if you did find a way to create a script to perform the calculations, I don't know if the PV+ (as a closed Windows CE system) would have the computing horsepower needed for the calucations.

Just my .02...

I have another question, or problem I guess. If I do the counting in the PLC, how can I get it to a database with a timestamp on it. These will be written every hour, so each datapoint will represent an hour of runtime and it needs to be stamped as to what hour of what day the data refers to. With the limitations of the PV+, I am unsure how I can get a timestamp on the datapoints. Thanks.

When you send the data, can you also send the time and date information from the PV+? There are system tags that contain this information.

As another option, you could use the remote time and date global connection on the PV+ to make sure that information is synchronized with your PLC.

Thanks a lot, this is exactly what I needed. This site kicks *** once again.
