Processor and Performance
The CPU has a clock speed of 800 MHz and supports multitasking real-time parallel processing, with a control cycle of up to 1 ms. The memory configuration includes 24 MB controller memory, 8 MB battery buffer SRAM, and 16 MB DRAM, supporting up to 1500 I/O points. Supports up to 16 tasks to be executed in parallel, with SOE event recording resolution less than 1 ms.
[Communication Interface]
Onboard 4 100 Mbit/s Ethernet interfaces (RJ45), 2 RS232C serial ports (COM3/COM4), and 1 diagnostic interface. There are also 2 slots for assembling communication interface modules, which can expand up to 2 fieldbus interface modules (PM902F/PM901F up to 2, PM904F up to 4). Supports mainstream industrial communication protocols such as Modbus TCP, Modbus RTU, PROFIBUS DP, Telecontrol, CAN, etc.
I/O expansion capability
Up to 10 S700 I/O modules can be directly connected (via terminal unit base), and more I/O clusters can be expanded through Coupler Bus and I/O Bus, supporting remote I/O, transmitter, actuator, driver and other field device access.
[Redundant Configuration]
Support 1:1 dual machine hot redundancy architecture, with redundancy switching time not exceeding 10 ms, ensuring seamless system operation in case of hardware failure. The redundancy range covers the CPU, communication bus, and I/O system.
[Physical Specifications]
Dimensions: width 227 mm x depth 95 mm x height 152 mm, net weight approximately 1.1 kg. Protection level IP20, surface coated with G3, suitable for use in harsh industrial environments such as corrosion and humidity, and can be installed inside the control cabinet without additional casing. The working temperature range complies with IEC 60721-3-3 3K3 level.
Power Supply and Software
Requires external 24 VDC power supply. The module itself does not contain an operating system, and the operating system needs to be loaded during software installation. Programming configuration must be done using Freelance 2013 or higher software. Supports SD card for controller backup and firmware updates. Optional LCD display unit TD 951F (not included in this module) and battery TA 951F (not included in this module).
Certification and Compliance
CE, cULus, ISA-S71.04 G3, UL Class I Div. 2, NAMUR NE21 certification. Compliant with RoHS Directive 2011/65/EU and Amendment 2015/863, WEEE Category 5, HS Code 85371091.
Typical application areas
Industrial scenarios that require high reliability and medium to large I/O scale include oil and gas, thermal power generation and new energy, chemical process control, water/wastewater treatment, pulp and paper, cement and building materials, metallurgy, and district heating.
