performance parameter
Processor: Equipped with high-performance 32-bit microprocessors such as Motorola PowerPC (MPC8247), it has strong data processing capabilities, fast running speed, and can quickly execute complex program instructions, achieving a 2-millisecond I/O scan time.

Memory: Equipped with 10MB of RAM, of which 2M is battery backed SRAM used to store critical programs and data, ensuring that data is not lost in case of power failure; There are also 8M SDRAM and 4M flash ROM, providing sufficient space for program execution and data storage. In addition, an onboard compact flash high-capacity storage system with a capacity of up to 512MB can also be optionally selected.
Communication interface: equipped with 100Mbit/S Ethernet network connection for communication between controllers, operation stations, and engineering tools; It also has two serial line interfaces, one for MODBUS communication and the other for diagnosis.
Product Features
Powerful function: It is a DCS that runs on PLC hardware, especially suitable for small applications, can handle 300 I/O signals, and does not have an operating system. Supports multiple programming languages, such as ladder diagrams, C language, FBD function block diagrams, ST structured text, etc., making it convenient for users to develop and debug programs. Eight loops and priority tasks can be configured, with adjustable task cycle times, and loop PLC type tasks can run as quickly as possible.
Easy integration: Supports multiple communication protocols such as Modbus, Profinet, etc., and can exchange data with multiple devices. The S700 I/O module can be directly inserted into the CPU module or used as a remote I/O module through Profibus, with up to eight modules connected to one controller. Third party I/O can be remotely controlled through MODBUS ASCII/RTU, IC60870-5-101 protocol, or Profibus connection.
Safe and reliable: It has high reliability and stability, and can operate stably in harsh industrial environments. The small front panel display can directly display status and diagnostic information, and can also lock the controller with keys to prevent downloading applications and firmware, enhancing security. Implemented short-circuit and disconnection detection for each channel to ensure stable system operation.
Application areas: Widely used in various industrial automation control systems, such as industrial production lines, power systems, petroleum, chemical, metallurgical, building materials and other fields, as well as transportation systems, energy management systems, building automation and other scenarios, it can achieve precise control and optimized management of the production process.
