IC200CMM020  串行通信模块  可以将数据从发送器发送到接收器

IC200CMM020是GE设计的Versamax串行通信模块。该IC200CMM020在由 Genius 网络接口单元控制的 Versamax I/O 站中用作 Modbus RTU 主站。串行通信模块（如IC200CMM020）可以安装在 I/O 站的任何位置。每个 I/O 站最多可服务于两个串行通信模块。

外部设备可以通过串行端口接收 5V 电源。大约有 100mA 的功率可供外部设备使用。这可能因串行设备的接线方式而异。电流消耗取决于串行线路端接、双工模式、串行线路活动以及可能需要额外 5V 电源的外部适配器的使用。最大负载量为200mA;内部电流限制开关可防止损坏，并根据需要锁定通信和外部电源流。一旦模块的 LED 变为琥珀色，用户必须识别过引情况，当情况解决后，通信和电源流将恢复。

IC200CMM020模块的配置是使用 GENERIC-COMM 完成的，这是编程器的一项功能。在模块和以太网 NIU 之间进行通信之前，必须将 %AI 和 %AQ 数据的模块默认参考地址的数据长度从初始长度更改为零。在收到有效配置之前，IC200CMM020无法在串行网络上进行通信。IC200CMM020模块支持Modbus RTU主站协议。要作为主服务器运行，模块必须接收来自远程主机的命令。命令通过 I/O 站的 Genius NIU 的输入和输出内存区域在模块和远程主机之间交换。

IC200CMM020  串行通信模块是一种用于在设备之间进行数据传输的电子元件或设备。它采用串行通信协议，通过一条数据线路逐位传输数据。

IC200CMM020  串行通信模块通常包括发送器和接收器，可以将数据从发送器发送到接收器。它可以用于连接各种设备，如计算机、传感器、控制器等，以实现数据的传输和交换。

IC200CMM020  串行通信模块的主要特点是数据传输速度较慢，但传输距离较远，抗干扰能力较强。它通常采用异步通信方式，即发送方和接收方不需要严格的时钟同步。

总之，IC200CMM020  串行通信模块是一种非常重要的电子元件，它在各种工业和科学领域中都有广泛的应用。

The IC200CMM020 is the Versamax serial communication module designed by GE. The IC200CMM020 is used as a Modbus RTU master in a Versamax I/O station controlled by the Genius network interface unit. Serial communication modules, such as IC200CMM020, can be installed anywhere in the I/O station. Each I/O station can serve up to two serial communication modules.

External devices can receive 5V power through the serial port. About 100mA of power is available for external devices. This may vary depending on how the serial device is wired. Current consumption depends on serial line termination, duplex mode, serial line activity, and the use of external adapters that may require an additional 5V power supply. The maximum loading capacity is 200mA; The internal current limit switch prevents damage and locks the flow of communication and external power sources as needed. Once the module's LED turns amber, the user must identify the overloading situation, and when the situation is resolved, the communication and power flow will resume.

The configuration of the IC200CMM020 module is done using GENERIC-COMM, which is a function of the programmer. Before communication between the module and the Ethernet NIU, the data length of the module default reference address for %AI and %AQ data must be changed from the initial length to zero. The IC200CMM020 cannot communicate over a serial network until a valid configuration is received. The IC200CMM020 module supports the Modbus RTU master protocol. To run as a master server, the module must receive commands from the remote host. Commands are exchanged between the module and the remote host via the input and output memory areas of the Genius NIU at the I/O station.

The IC200CMM020 Serial communication module is an electronic component or device used for data transmission between devices. It uses serial communication protocol to transmit data bit by bit through a single data line.

The IC200CMM020 serial communication module usually includes a transmitter and a receiver, and can send data from the transmitter to the receiver. It can be used to connect various devices, such as computers, sensors, controllers, etc., to achieve data transmission and exchange.

The main feature of IC200CMM020 serial communication module is that the data transmission speed is slow, but the transmission distance is long, and the anti-interference ability is strong. It usually uses asynchronous communication, that is, the sender and receiver do not need strict clock synchronization.

In short, IC200CMM020 serial communication module is a very important electronic component, which has a wide range of applications in various industrial and scientific fields.
