Hello,
I read the document "DIV.O5.ME.99 PLC Programming Guidelines for robotized cell.pdf".
You require PLC programming in LD (Ladder Diagram).
We do not use LD (Ladder Diagram).
I am requesting an exception.
We use programming in SCL.
It's more efficient. Organized
I can use DIAGNOSTICS.
I see an error in the diagnostics on the HMI, I don't need a programmer + PC Tia Portal.
In 90% of cases, the operator detects the defect.
In the event of a major failure, Gemax will connect via VPN.
An outline of our program in SCL:
In LD (Ladder Diagram) colored paths, relays but it is a lot of lines and confusing.
DIAGNOSTICS cannot be used on HMI in LD (Ladder Diagram).
I am sending some photos of HMI.
Main screen:
Manual control screen:
If there is a collision and the movement cannot be realized, the button is greyed out.
After pressing, DIAGNOSTICS will be displayed with a list of collision conditions.
I can display a submenu in diagnostics.
For example, after pressing the "Basic position" line,
the conditions for evaluating the "Basic position" status are displayed.
This way you can find a specific sensor that is bad.
Diagnostics is functional for all collision states, all steps in the automaton chain,
all evaluations of the position of pneumatic cylinders, etc.
In this way, the operator detects the fault without a PC.
In LD (Ladder Diagram) this is not possible.
I am sending a video for demonstration.
Consider using an LD (Ladder Diagram). It's not used much anymore.
I recommend SCL.
We solve problems with diagnostics or by connecting using a VPN.
