The 8715-CA-BI bus interface module communicates with the host controller over a local area network (LAN)

Description

Detailed analysis of 8715-CA-BI bus interface modules communicating with host controllers over local area networks (LAN)

I. Product overview

Model: 8715-CA-BI
Type: Bus Interface Module (BIM)
Main function: Communication with host controller via local area network (LAN)
2. Communication characteristics

Communication method:
The 8715-CA-BI bus interface module uses local area network (LAN) as a communication medium to realize data exchange with the host controller.
Supports high-speed data transmission, which may reach or exceed 6 Mbaud (inferred from the description of the MTL 8715-CA-BI logic module).
Modular design:
The module is a fully modular I/O solution with an open architecture that allows flexibility to adapt to different industrial automation system requirements.
It can communicate with a variety of different fieldbuses, including but not limited to protocols such as PROFIBUS, for efficient data transmission and communication.
Electrical and physical characteristics

Electrical parameters:
Power supply voltage: 18-32V DC
Isolation voltage: up to 1500V AC to ensure the safety of signal transmission.
Frequency response range: DC-10kHz, to meet a wide range of signal transmission needs.
Linearity error: ±0.1%, to ensure the accuracy of signal transmission.
Physical dimensions and installation:
Mounting method: 35mm DIN rail for easy deployment in industrial automation environments.

Fourth, function and application

Signal isolation and transmission:
The 8715-CA-BI module has signal isolation function, which can prevent interference between the input loop and the output loop to ensure the quality of the transmitted signal.
It is mainly used to isolate and transmit 4-20mA analog signals, the input signal is 4-20mA DC, and the output signal can be 4-20mA DC or 1-5V DC.
Digital quantity control:
As a digital control module, 8715-CA-BI provides 8 digital input ports and 4 digital output ports.
These ports can be used to connect various types of sensors and actuators and support a variety of control modes, including switches, buttons and relays.
Security features:
In some applications (such as the MTL 8715-CA-BI logic module), the module also has safety-related features, such as 16 safety-related digital inputs, 8 anti-short circuit power supplies, etc., to ensure high safety of industrial automation systems.
