The serial communication module CMM201-0201 has the following features:
Independently complete communication tasks, enabling data exchange both with the NJ200 CPU and with external serial port devices.
Two extended RS485 serial ports that can support internal Modbus master communication as well as custom protocol communication, with a selectable baud rate range of 2400 to 115,200 bps.
An extended RS232 serial port that does not support programming, but only supports communication and program downloading.
Divide the input and output areas: it can simultaneously support up to 256 digital inputs, 256 digital outputs, 120 analog inputs, and 120 analog outputs, with each input and output area not exceeding 240 bytes.The station communication module CMM201-0103 Profibus has the following features:
Standard PROFIBUS-DP slave interface: DP-VO/V1 protocol, compliant with IEC61158 and the Chinese national standard GB/T20540-2006: Part 3—Fieldbus for Industrial Control Systems Based on Digital Data Communication for Measurement and Control;
The baud rate is adjustable, with a maximum baud rate of 12M.
The maximum number of such slave stations that can be connected to a Profibus bus is 30.
Maximum expansion I/O modules: 7 expansion I/O modules:
Smart module with powerful self-diagnosis capabilities—when a fault occurs during module operation, it can automatically reset and restart itself.
The unique data security output function gives the control device enhanced security features:
Comprehensive LED indicators: power, module activation, module operation, fault, PROFIBUS bus operation, and fault—all covered.
LED indicator on the face.The dual-channel CAN communication module CMM201-0204 has the following features:
Dual CAN interfaces, custom protocol communication;
Baud rate freely programmable, supporting basic baud rates from 5K to 1000K;
The maximum input for internal communication is 120 characters (240 bytes), and the output is also 120 characters (240 bytes).
Smart module with powerful self-diagnosis capabilities; when a fault occurs during module operation, it can automatically reset and restart itself.
The unique data security output function gives the control device enhanced security features.
Comprehensive LED indicators: Power, module operation, fault, and CAN bus transceiver—all fully indicated by LEDs.The Ethernet communication module CMM201-0105 has the following features:
Supports the standard MODBUS TCP slave protocol;
Supports up to 8 master stations accessing data simultaneously;
The communication rate is 100 Mbps;
The unique data security output function gives the control device enhanced security features.
Comprehensive LED indicators: LEDs indicating module operation, faults, Ethernet communication, and more;
Supports hot-swapping.*The information provided in this text is merely a general description and introduction to the product’s features. The content of this document may change as the product undergoes further development. The right of interpretation belongs to Aotuo Technology Co., Ltd.
