Located in the Project Tree of RSLogix 500 - toward the bottom you'll find "custom data monitor" and "trends".

Do you ever use these ("custom data monitor" and "trends") when writing/using a program constructed for a customer?



And will you ever discuss these issues in the future; in a instructional video?



Thank you,

klm

KLM,

Sure I use them both periodically. Not usually while programming, but generally on site during checkout and startup. There are times that I prepare the custom monitoring page beforehand if I know I have some manipulations that I will need to do from the Logix software. Generally though I have some sort of operator interface and I handle anything I need there. Same with the trends, but there are times that I need a quick trend to get a better idea of what's happening in a process and I use the Logix trends.

I have put together a vid on the custom data monitor. You can find it filtered out here:

You will have to be logged into at least stage 1 to view it. I will work on a trend vid and post it in the future.

Thanks,

Russell

I went ahead and reviewed the "custom data Monitor" video.

I always learn something. Your efforts are appreciated. I'm looking forward
to watching the "trends" video. BTW I think "trends" would be good for troubleshooting.(just my opinion; I'm still learning).

What is a good "data logging" software. I went to an automation fair and the term "OPC" was thrown-around. Is that a data logger or is OPC some kind of 'driver' that makes different applications work together.

I don't mean to take up too much of your time - so I'll just say Thanks for now.

I'm glad you are still getting new stuff! I think you have been with us longer than most subscribers so the fact that you are still learning says a lot.

On to OPC. OPC originally stood for OLE for Process Control. I understand that now it has expanded its role so much from its original purpose that the foundation that controls all things OPC just wants it to be OPC without any higher and glorious meaning. I would assume that most of the OPC offerings you were looking at were, as you mentioned, drivers that allow connectivity from an HMI/SCADA system to a PLC platform. The important thing about it is that it is a standard that allows common manner for different types of software to connect to the hardware platforms. In theory a PLC vendor could write an OPC driver and any software package compatable with OPC would then be able to communicate with that PLC system.

There are tons of datalogging types of software out there. What is good really depends on your needs. The micrologix 1100 and 1400 actually do datalogging at the processor level and allow for a kind of batch export of the data. In my opinion pretty much useless for most applications, but its there. Same with many HMI's such as the AB Panelview. As you move up to SCADA packages, most of them have datalogging that allows the data to be stored locally on the SCADA computer or on a remote datalogging machine. They usually have datalogging files that their system can read and write to as well as the capability to send the data to a more open system such as MSSQL or Oracle databases. Then you have software such as Wonderware's Historian or Rockwell's RSSql that are dedicated data logging systems often with data analysis tools available or built in. There is also the inductive automation setup that is built around a SQL compatable database as its core.

Reasearch that stuff a little and feel free to post more questions - dont worry about my time. I post when I can.

Happy Googling!
