Schneider Electric Telepace Studio Software Development When
Schneider Electric Telepace Studio Code And Then

The ladder evaluation moves down Column 1 until it reaches the 8th Row, after which the evaluation then continues at the top of Column 2 and moves down to Row 8 again.

This process continues until the entire network has been evaluated.

If there is more than one network, evaluation continues to the next sequential network in the program until the entire program has been evaluated.

Schneider Electric Telepace Studio Software Development When

I have been doing software development when 10 years old and have never looked back.

It is a powerful tool for developing, debugging, monitoring and documenting ladder logic programs.

SCADAPack controllers executes ladder logic and C-application programs simultaneously, providing you with maximum flexibility in implementing your control strategy.

An ASCII character is 8 bits and a HEX character is 4 bits, so with every ASCII value you will have a 2 digit HEX value.

Schneider Electric Telepace Studio Code And Then

What I am trying to do is make a ST program that reads in ASCII from a barcode and then turn it into a string, and finally into a hex number, which will be stored for historic records in a server.

I still am trying to grasp function blocks and I dont think those are the solution to this anyway.

I know I want to set up a variable, then do the methods described, but I dont know really how to proceed.

If it helps, it is for the Schneider Electric SCADA systems.

The issue is that I have no idea on Modbus stuff and it closely resembles VBScripts which I also never worked with before.

I only studied a little programming in my CS studies but it was nothing like this stuff.

In googling, there isnt any code out there I can look at to see what they did to compare my process.

I am making a program that will convert the barcodes into ASCII (per the project wants) hex which will be treated as a serial number.

Once it logs the serial, it will monitor several analog points and then reset once the process is over, but keep a log of all the SNs, model numbers, and trends.

I just am having trouble finding a hex conversion that is efficient.

I originally thought to use Telepace Studio as that is what was used to configure the SCADAPack, but it was decided that we are going to instead do the SN assignment in ClearSCADA itself.

I was originally going to do it through function blocks (which I am still trying to grasp, coming from a Comp Sci background), but it seems that ST is more efficient.

Hope this is clearer.

Share Report Save Continue this thread level 1 6 years ago Manipulating strings as you describe is not a function that PLCs naturally do well and the level of complication in the coding required for this application means that the program will likely have bugs that are hard to find.

My suggestion is to run the Modbus signal either straight into your PC with the SCADA on it or into a networked Modbus gateway unit.

Then access the data directly from the SCADA using a Modbus IO driver.

If you can get the data you want stored in the PLC you can definitely move it around with modbus though.

I dont know what scanner they are using, but it will communicate via serial.

Its just tough getting to talk int hat language as its not quite at intuitive to me as conventional languages with a Comp Sci background.

Its great for someone who pretty much got thrown into a field of Computer Science that was never really covered in Computer Science.:) 2 Share Report Save level 1 6 years ago (Schneider has at least 3 competing SCADA systems -- Citect SCADA, Wonderware Intouch, and Wonderware System Platform.

Which are you talking about) 1 Share Report Save level 2 6 years ago Its ClearSCADA 2014 R1.1.

They are slowly integrating Wonderware.

And I actually coded out some ST that seemed to get the job done.

I am looking forward to beta testing their 2015 and seeing how it is going to be with Wonderware and other things that Schneider bought that they are going to start putting together into one program.

Share Report Save level 1 6 years ago Perhaps Im not understanding what you are trying to do, but ASCII and HEX are exactly the same on the binary level, its just how you are displaying the value.
