7 Common PLC Programming Languages in Industrial Control

1. Omron PLC Programming Software

Omron PLC programming software integrates CX-Programmer V9.5, providing comprehensive software support for Omron PLC programming, fully supporting 32/64-bit WIN8 systems, and available in multiple languages, including Simplified Chinese.

It can configure networks, programmable terminals, servo systems, electronic temperature controls, etc. It is suitable for those responsible for installing FA systems, designing FA systems, and managing and maintaining FA systems who already possess electrical system knowledge (electrical engineers or equivalents).

2. Mitsubishi PLC Programming Software

Mitsubishi PLC programming software is suitable for the entire series of programmable controllers including Q, QnU, QS, QnA, AnS, AnA, FX, etc.

The Mitsubishi PLC programming software GX Developer is positioned as a comprehensive development platform for programmable controllers, supporting ladder diagrams, instruction lists, SFC, ST, FB, Label language programming, network parameter settings, online program modifications, monitoring, and debugging, with remote read/write PLC program capabilities.

3. Siemens STEP 7

STEP 7 is Siemens’ most classic programming software, corresponding to the Siemens S7-300/400 series, representing older models of Siemens PLCs.

STEP 7 has the following functions: hardware configuration and parameter settings, communication configuration, programming, testing, startup and maintenance, file archiving, operation and diagnostics, etc. All functions of STEP 7 come with extensive online help; by clicking on an object with the mouse and pressing F1, relevant help for that object can be obtained.

In STEP 7, projects are used to manage the hardware and software of an automation system. The SIMATIC Manager centrally manages projects in STEP 7, allowing easy browsing of data from SIMATIC S7, M7, C7, and WinAC. All necessary SIMATIC software tools required to implement various functions of STEP 7 are integrated within STEP 7.

4. Siemens TIA Portal

TIA Portal is the abbreviation for Totally Integrated Automation Portal, a new all-in-one automation software released by Siemens Industrial Automation Group.

It is the industry’s first automation software that uses a unified engineering configuration and software project environment, applicable to nearly all automation tasks. With this new engineering technology software platform, users can quickly and intuitively develop and debug automation systems.

5. Schneider Programming Software

Unity Pro XL is Schneider Electric’s core automation product, representing a new generation of hardware and software automation platform. Its innovative design shortens development time, and the flexibility of the processor allows for higher performance.

Based on openness and collaborative application of tools, Unity achieves a higher level in software development and control system operation, prioritizing productivity improvement.

6. Panasonic PLC Programming Software

Panasonic FP series PLC programming software FPWIN GR is a powerful and user-friendly system programming software. The downloaded compressed package contains a serial number that has been tested to work.

The installation includes software required for MEWNET-H link systems, setting software for various intelligent modules, programming manuals, and this document is a PDF format file explaining PLC instructions.

7. Delta WPLSoft PLC Programming Software

The latest version of Delta’s WPLSoft PLC programming software can simulate the execution of PLC programs on a computer without a real PLC. First, click simulation, then click the ladder diagram monitoring. You can right-click to control the status of some variables to achieve simulation. Note that it must be connected to a PLC.

After starting the simulator, monitoring, uploading and downloading programs, and other communication functions can be performed without selecting a communication interface; the operation method is the same as when actually connected to a PLC.

The simulator supports timers and counters, but the running time of timers and counters may vary depending on the user’s computer execution efficiency. The timer processing method is the same as that of the DVP-ES/SA series PLCs.
