Siemens SIMATIC S7-300 PLC
The Siemens SIMATIC S7-300 is the mid-range modular PLC that dominated Saudi industrial automation from the 1990s through to the 2010s and remains the installed PLC platform for a large proportion of existing Saudi process, manufacturing, and infrastructure control systems requiring ongoing spare parts supply, maintenance, and incremental program modifications. The S7-300's CPU 315-2 PN/DP and CPU 317-2 PN/DP models remain widely installed in Saudi ARAMCO process automation systems, SABIC plant control systems, and NWC water treatment automation — making S7-300 spare parts, memory cards, and communications modules a continuing maintenance requirement for Saudi industrial facilities.
For Saudi maintenance teams, the SIMATIC S7-300 represents the ongoing requirement for CPU modules, I/O modules (SM 321/322/323/331/332/334), communication modules (CP 343-1 Ethernet, CP 341 serial), PROFIBUS DP master/slave modules (IM 360/361 interconnect, DP master CP 342-5), and power supplies (PS 307) — the spare parts inventory required to maintain existing S7-300 installations without production interruption. Step 7 Classic V5.7 programming software runs on current Windows 10 and Windows 11 systems, enabling Saudi maintenance engineers to modify S7-300 programs on modern laptops without legacy operating system VMs.
New installations using S7-300 are diminishing as S7-1500 becomes the standard for new projects, but S7-300 brownfield expansion and upgrade projects remain significant in Saudi Arabia. Upgrade paths include SIMATIC S7-PLCSIM Advanced for offline testing of S7-300 program changes before download, and migration to S7-1500 with STEP 7 code migration tools for facilities planning major PLC modernisation.
Razz Middle East stocks S7-300 CPU, I/O, and communication modules for spare parts and brownfield expansion projects throughout Saudi Arabia.

Key Features & Benefits
- Large installed base across Saudi Arabian ARAMCO, SABIC, NWC, and manufacturing facilities makes S7-300 spare parts supply a critical ongoing maintenance requirement for Saudi industrial operations.
- CPU 315-2 PN/DP and CPU 317-2 PN/DP provide combined PROFIBUS DP master/slave and PROFINET IO controller in one CPU, supporting both PROFIBUS legacy field devices and modern PROFINET I/O.
- STEP 7 Classic V5.7 compatibility with Windows 10 and Windows 11 enables Saudi maintenance engineers to modify S7-300 programs on current laptops without legacy operating system virtual machines.
- Modular I/O expansion via SM 321/322/331/332 modules supports brownfield expansion of existing Saudi S7-300 installations without replacing the entire PLC platform.
- MMC memory card retains the user program during power loss and enables program transfer between CPUs without a programming laptop — a useful feature for field spare CPU replacement.
- SIMATIC S7-1500 migration path with Step 7 code migration tools provides a structured upgrade route for Saudi facilities planning S7-300 platform modernisation.
- Full SIMATIC ET 200 distributed I/O compatibility enables remote I/O expansion of existing S7-300 systems at Saudi plant satellite control stations without replacing the main S7-300 panel.
