Hardware Structure: The CPU motherboard contains a microprocessor, RAM, a real-time clock, LED indicator lights, a start button, and a compact flash interface. The baseboard has two RJ45 Ethernet ports (CN1, CN2) for connecting to the control network, and two RJ45 serial ports (COM3, COM4). Among them, COM3 is an RS-232C port with a modem control signal, and COM4 is isolated and used for connecting to the configuration tool.

Functional Features: It supports CPU redundancy to achieve high availability, including the CPU, CEX bus, communication interfaces, and S800 I/O. It has reliability and a simple fault diagnosis program, adopts a modular design, and allows for gradual expansion. It has IP20 class protection and does not require a storage module. It can be configured as an 800xA control builder and has obtained a complete EMC certification. Based on standard hardware, it is used to achieve optimal communication connections, such as Ethernet, PROFIBUS-DP, etc., and has built-in redundant Ethernet communication ports.

The ABB 3BSE018157R1 (PM861AK01), as a controller module of the ABB AC 800M series, supports multiple communication protocols to meet the data interaction and collaborative work with various devices and systems in different industrial scenarios. The common communication protocols are as follows: Ethernet/IP: This is an industrial communication protocol based on Ethernet, which combines the high-speed data transmission capability of Ethernet with the application layer protocol of industrial automation. Through Ethernet/IP, the ABB 3BSE018157R1 controller module can conduct real-time data exchange with devices that support this protocol (such as intelligent sensors, actuators, other controllers, etc.), and achieve functions such as device status monitoring and control instruction sending. It allows for the rapid transmission of a large amount of data in the industrial network, improving the degree of automation and response speed of the production process. Modbus TCP: Based on the Modbus protocol over Ethernet, Modbus TCP is a widely used industrial communication standard. Through Modbus TCP, this controller module can conveniently communicate with other devices that support the Modbus protocol, such as instruments, PLCs, etc. It uses the standard TCP/IP protocol for data transmission, and the data format is simple and clear, making it easy to achieve interoperability between devices. In industrial automation systems, it is often used for data interaction and integration between devices from different manufacturers.

PROFIBUS DP: PROFIBUS DP (Decentralized Periphery) is a high-speed data communication bus protocol for the field level. The ABB 3BSE018157R1 controller module can act as a PROFIBUS DP master station or slave station to communicate with field PROFIBUS DP devices (such as distributed I/O modules, sensors, actuators, etc.). As a master station, it can configure, collect data from, and control slave station devices; as a slave station, it can receive instructions from the master station and return the corresponding data. This protocol has high real-time performance and reliability in the industrial field and is suitable for control scenarios with high real-time requirements. CANopen: CANopen is an application layer protocol based on the CAN (Controller Area Network) bus. It provides a standardized communication method for the industrial automation field, enabling devices from different manufacturers to be compatible with each other and work collaboratively. If the ABB 3BSE018157R1 controller module supports the CANopen protocol, it can communicate with other devices in the CANopen network to achieve functions such as parameter setting, status monitoring, and control of the devices. The CANopen protocol is often used in industrial control scenarios with high real-time and reliability requirements, such as robot control and motion control. Modbus RTU: This is a serial communication mode of the Modbus protocol, using serial communication interfaces such as RS-485. Although compared with the high-speed transmission of Modbus TCP based on Ethernet, Modbus RTU is more suitable for some industrial fields where the communication rate requirement is not particularly high, but there are certain requirements for wiring costs and distances. By supporting Modbus RTU, the ABB 3BSE018157R1 controller module can connect and communicate with some traditional serial communication devices to achieve data reading and writing operations.
