BMX P34 2020 — Schneider Electric Modicon M340 PLC
The Schneider Electric Modicon M340 is a mid-range programmable logic controller (PLC) platform covering control system applications from 64 to 1024 I/O points, built on a modular rack architecture that accommodates digital, analog, and fieldbus communication modules in a standardised backplane with deterministic cycle times suitable for process and machine control applications. The M340 CPU delivers scan times from 0.8 ms per 1000 instructions, supporting high-speed discrete I/O for machine control and analog loop control with 1 ms update rates for fast PID regulation. The processor runs Unity Pro IEC 61131-3 programming software, supporting all five standard languages (LD, FBD, SFC, ST, IL) with online program modification, enabling in-service programme changes without production interruption.
The M340 platform's communication capability is extensive: the BMX P34 2020 processor module includes a built-in Ethernet port for SCADA and OPC connectivity, Modbus Serial, and CANopen master, with optional cards for PROFIBUS DP master, EtherNet/IP scanner, and Foundation Fieldbus H1. This broad protocol coverage enables the M340 to serve as the PLC for process plants integrating instruments and drives from multiple manufacturers — the typical situation in Saudi Arabia's large process plant DCS-plus-PLC architectures. The M340 is fully compatible with the Vijeo Citect SCADA and EcoStruxure Machine Expert programming environment, providing a single-tool engineering experience for Schneider Electric complete automation solutions.
In Saudi Arabia, the Modicon M340 KSA is widely deployed across water treatment, HVAC building automation, light process, and machine control applications. NWC water treatment plant SCADA systems use M340 PLCs for pump station and treatment process control with Modbus communication to the SCADA server. HVAC building automation systems for large commercial projects from Johnson Controls and Honeywell frequently incorporate Schneider Electric M340 PLCs for plant room control with Modbus integration to the BMS. Process equipment skid manufacturers supply skid automation using M340 for international oil and gas and petrochemical clients.
Razz Middle East supplies Modicon M340 systems with Unity Pro programming, SCADA integration, and startup support for water, HVAC, and process control projects across Saudi Arabia.

Key Features & Benefits
- Built-in Ethernet port supports simultaneous Modbus TCP SCADA connection and EcoStruxure cloud data upload without additional communication modules, reducing system cost for SCADA-connected process control applications.
- 0.8 ms per 1000 instructions scan time supports machine control applications requiring tight I/O response timing, as well as process control applications needing fast PID loop update rates.
- Online program modification via Unity Pro enables plant automation engineers to update control logic during production without stopping the controlled process, reducing planned maintenance shutdown frequency.
- CANopen master capability built-in connects the M340 to Schneider Electric Altivar drives and other CANopen field devices without an additional fieldbus card, reducing system cost for drive-integrated machine automation.
- IEC 61131-3 all-language programming in Unity Pro enables Saudi system integrator engineering teams to choose the most appropriate language for each application — ladder for interlocks, FBD for control loops, SFC for sequential processes.
- Broad optional fieldbus portfolio covering PROFIBUS DP, EtherNet/IP, and Foundation Fieldbus H1 enables integration into third-party DCS and instrument networks at ARAMCO and SABIC process plants.
- Hot standby redundancy configuration with dual M340 CPUs provides automatic failover for critical process applications requiring high availability, satisfying water treatment and HVAC plant control continuity requirements.
