I am fine with how it is working for me. I have used the single register addresses and they functioned fine. For an example for an integer that was an %R-0321 in my Horner PLC's the offset for Modbus/TCP is 6000, so in MODBUS/TCP it would be HR6321. And this worked fine. But, with the Real number in Horner it would be designated the same %R321 and it would also include %R322. So in Modbus/TCP it is designated 6321 the same as the integer register. However, when I tried to use HR6321 for this application it just gave out weird scrolling numbers. I finally tried the reverse and set the register in the app for HR6322 and it works fine.
I don't mind it. I just have not seen this before. And I have used other SCADA programs. I don't know if it applies to other PLC's since I haven't used this app with any other PLC's, but I might.
I really do like this app, it is going to do a whole lot for the company I am using it with. They want to stay totally informed about what is happening with this waste treatment plant at all times. So this will do that for them. I already had this PLC connected to the Internet through a CellPhone interface full time. This allowed them to access machine on their PC's and laptops just like they were at the machine through a program from Horner called Envision. The PLC also sends the emails of the data log daily and the alarm log daily. And to further make this fun it sends out an email to them if there is an alarm that comes on. Attached to the email is a .csv file with the alarm log on it so that they could see what the alarm was without having to go to their PC or laptop and logging in.
However, with the latest update in IOS to ver. 7 the .csv files became corrupted when they tried to open them. The files were still good if they were opened in an Android phone or on the PC's. So it was Apple's software not liking the format of the .csv file. I know there is a difference between a .csv file for Mac and Windows, but it never made a difference until the IOS 7 update.
That was why I came looking for something to help out. And I found your solution. And like I said it is going to work out great. I can't wait to present it to the engineers and chemist at this company.
I got this to work and it works fine. This program will work well for what my customer wants.
The one thing I found out was that the structure for the real numbers is different than I am used to. In Modbus, Horner, A/B and other PLC systems when you address a real number it takes up two address, and you usually address it by the lowest numerical address. I.e, if you have a Real Number that is in location say register 1 & 2. Most systems address this as address 1, but I found after much angst that in the SCADAMobile.app it is addressed as HR2. Now that I know it won't be a problem in the future.
Thanks for the help,
Thank you, I will give that a shot. I should be able to finish my spreadsheet later today so I can load in my new one. I have every hope that it will work fine for what I am doing. So this will be a very good thing for the company I am working with.
Thank you, that should work for what I want to do.
