In the field of industrial automation, small programmable logic controllers (PLCs) need to provide high processing speed, flexible I/O expansion, rich communication interfaces, and reliable memory backup in a compact size. The OEMax NX70 series controller is designed to meet these requirements, using high-speed ASIC technology with a basic instruction processing time of only 0.2 μ s/step, supporting up to 384 I/O points, and providing multiple dedicated modules (analog, temperature, high-speed counting, motion control, etc.) as well as strong communication protocols. This article will provide a comprehensive and in-depth technical analysis of the series of controllers from the aspects of system configuration, hardware specifications, addressing methods, installation and wiring, programming instruction set, communication protocol, and selection guide.
Selection guide and ordering information
When choosing the NX70 system, the following factors should be considered:
I/O points: Select the number of slots on the motherboard (2-12 slots) based on the actual input/output quantity. Each 16 point module occupies 1 slot, and a 32 point module occupies 1 slot but consumes 2 word addresses.
CPU performance: When large program capacity, dual communication ports, RTC, and PID functions are required, select CPU 70p2; Otherwise, select CPU 70p1.
Power type: When on-site AC 110/220V and 24V auxiliary power supply is required, select POWER1; When only 5V is needed and there is less I/O, choose POWER2; Choose PWRDC for DC 24V power supply.
Special functions: Analog quantity, temperature, high-speed counting, pulse output, network communication, etc. require the selection of dedicated modules.
Programming cable: NX_CBLCPU2 (2m) or NX_CBLCPU1 (5m).
