Siemens programming software and program structure
1. Programming software
Siemens offers a wide range of programming software for SIMATIC series PLCs, mainly STEP MICRO/DOS and STEP MICRO/WIN; STEP mini; standard software package STEP7 S7 series PLC programming language is very rich, there are LAD, STL, SCL, GRAPH, HIGRAPH, CFC, etc. Users can choose a language programming and mix them in several languages ​​if needed.
2. Program structure
The program structure is mainly applicable to S7-3000 and S7-400. It has three programming methods: linear programming, step-by-step programming and structured programming.
The FPI series programmable controller is a small PLC product of Matsushita Electric Works of Japan.
FPI programming software and command system
1. Programming mode
NPST-GR provides three programming methods: ladder mode; statement table mode and statement expression.
2. Comment function
The NPST-GR can add annotations to I/O relays and output points, giving the user a clear view of the equipment and relays used for the relay.
3. Program check
NPST-GR can find grammar errors in the program and perform program verification
4. monitor
The NPST-GR monitors user-programmed programs and can run tests. The user can check the relay, register and PLC working status for easy debugging and modification.
5. System register settings
NPST-GR can set the contents of the N0.0-N0.418 system register, and select or input according to the prompt information on the screen, which is simple and convenient.
6. I/O and remote I/O address allocation
Use NPST-GR to assign I/O and remote I/O addresses to each slot on the host expansion board
7. Data management
Data management can save programs or data for data backup, or temporarily store data before passing to PLC. In programming applications, Siemens is a single bus, while Japan's Matsushita is a double bus;
There is also the difference between Siemens and Japan's Panasonic's input and output. Japan's Panasonic input is only X, and the output is only Y.
In fact, the language is the same, that is, the method is different, and the two can be converted to each other.
