4.1 Program structure

A sequential control program is divided into three sub-areas:

 Program header

 Program blocks

 End of program

These sub-areas form a machining plan.

Program

end

blocks

Program structure

Program header

The program header contains parameters that affect the entire

program, such as blank dimensions or retraction planes.

Program blocks

You determine the individual machining steps in the program blocks.

In doing this, you specify the technology data and positions, among

other things.

Technology data and

positions

Plain text, e.g. type

of machining

Block number allocated

by control

Symbol of machining cycle

Program block

Linked program blocks

For the "Contour turning", "Contour milling", "Milling", and "Drilling"

functions, program the technology blocks and contours or positioning

blocks separately. These program blocks are automatically linked by

the controller and connected by brackets in the work plan.

In the technology blocks, specify how and in what form the machining

should take place, e.g. centering first, and then drilling. In the

positioning blocks, determine the positions for the drilling or milling

machining, e.g. position the drill-holes in a full circle on the front

surface.

What to do if all four LEDs on the Siemens Controller PLC flash (DI disaster)?
- J
  Joshua LarsonJul 25, 2025
  If all four LEDs on the Siemens Controller PLC are flashing, it indicates a system error. Here's what you should do: 1. Stop the PLC (set the "PLC" switch to position 2). 2. Perform a hardware reset. 3. Read the diagnostic buffer using STEP 7 to analyze the error in detail. 4. Relay the diagnostic buffer information to the Hotline / Development Service. 5. If requested after the hardware reset, perform a general reset. You can then read the diagnostic buffer with the PLC in the Stop state. Alternatively, resetting or reloading the PLC program might resolve the issue. Even if the system returns to normal, send the diagnostic buffer content to the Development Office.

How to troubleshoot no MPI connection to Siemens Controller PLC?
- A
  Amanda CarrollAug 9, 2025
  If there is no connection via MPI to the Siemens Controller PLC, the MPI cable might not be plugged in or could be defective. Also, the STEP 7 software might not be correctly configured for the MPI card. To test, create a link with the programmer in the STEP 7 editor using the "Direct_PLC" connection. A number of node addresses should appear. If they don't, the MPI cable is likely defective or not plugged in.
