Versatility: The CMA198 module supports many types of input and output signals, such as analog signals, digital signals, switching signals, etc., and can adapt to different application requirements.
Signal processing: The module can process and convert input signals, such as converting analog signals to digital signals, or filtering, amplifying and other operations to ensure data accuracy and stability.
Data acquisition: The CMA198 module can collect data of sensor signals in real time and transmit it to the control system or monitoring system in order to monitor the status of industrial processes in real time.
Control function: In addition to data acquisition, the module can also be used to control the actuator and perform corresponding actions according to preset logic conditions and control algorithms, such as adjusting valves, adjusting motor speed, etc.
Communication interface: The CMA198 module is equipped with various communication interfaces, such as Modbus, Ethernet, etc., to achieve data exchange and communication with other devices or systems.
Measurement accuracy: 100 (the specific unit or meaning may vary depending on the application scenario)
Measurement range: 100 (again, the specific unit or meaning may vary depending on the application scenario)
Interface type: Supports a variety of interfaces, including input and output interfaces, to connect with control or detection components and executive components in industrial sites
Features:
Receive the input signal given by the control target, and calculate and output the result according to the program content set by the user
Operation results and program information can be saved in the internal output area, or extracted or set as other information by an externally connected device
Equipped with Modbus gateway function (modbus-TCP ≈ modbus-RTU protocol conversion function)
High speed counter (100kHz) x 5 channels, pulse /PWM output (65kHz) x 3 channels
Communication interface: Supports a wide range of serial (RS232/RS422/RS485) and Ethernet TCP/IP communication functions.
Supported protocols include the Modicon Modbus protocol (via serial communication), the Modbus/TCP protocol (serial Modbus variant for TCP/IP Ethernet communication), and the proprietary Bently Nevada protocol (for communication with 3500 rack configuration and data acquisition packages).
Power requirements: For Modbus RS232/RS422 I/O modules, the typical power consumption is 5 watts; For the Modbus RS485 I/O module, the typical power consumption is 5.6 watts.
Data refresh time: The data acquisition rate depends on the frame configuration, but the refresh time cannot exceed 1 second for all modules in the 3500 frame.
Operating temperature: It can operate in the temperature range of -22 to 150°F (-30 to 65°C).
Interfaces and connections: The CFP-1804’s interfaces and universal connections can be configured as input or output modules.
Communication: The CFP-1804 Ethernet/serial backplane can connect Compact FieldPoint I/O modules to high-speed Ethernet networks or RS232 serial ports. It also supports a wide range of third-party protocols such as Modbus TCP, Optomux, Modbus ASCII, Modbus RTU, and OPC, as well as NI event-driven Ethernet/serial protocols.
Configuration: IP address assignment and module configuration can be done using the NI Measurement & Automation Explorer (MAX) and Ni-FieldPoint drivers.
