CI853 RS-232模块协议：

COMLI 可用于构建 COM3 端口，也可以用于 CI853 端口。使用光纤转换器可以大大延长电缆长度（至几公里）。RS-232C是用于与COMLI串行通信的标准通信接口。CI853 支持热插拔。COMLI是ABB协议，用于控制器之间的数据传输。它专为半双工中的异步主/从通信而设计。COMLI 协议支持从应用程序控制的拨号调制解调器。CI853 在 COMLI 中同时支持主/从模式。

MODBUS RTU是一种标准协议，因其易用性和可靠性而被广泛传播。Modbus RTU 是一种开放式串行（RS-232 或 RS-485）协议，源自主/从架构，以半双工模式交换信息。Modbus 功能可以在 AC 800M 和 CI853 的 COM 端口上进行配置。模块冗余在 MODBUS RTU 中不可用。CI853 在 MODBUS RTU 中仅支持主模式。

COMLI 可用于构建 COM3 端口，也可以用于 CI853 端口。RS-232C是用于与COMLI串行通信的标准通信接口。CI853 支持热插拔。COMLI是ABB协议，用于控制器之间的数据传输。

MODBUS RTU 是一种开放的串行（RS-232 或 RS-485）协议，源自主/从架构，以半双工模式交换信息。Modbus 功能可以在 AC 800M 和 CI853 的 COM 端口上进行配置。

Siemens 3964R 可用于内置 COM3 端口，也可选择用于 CI853 端口。需要一个标准的 RS-232C/485 通信通道。

自定义串行通信可用于内置 COM3 端口（在 AC 800M 控制器上）和可选的 CI853 端口上。

CI853模块还支持热插拔。

CI853 RS-232 Module Protocol:

COMLI can be used to build the COM3 port, as well as the CI853 port. The use of fiber optic converters can greatly extend the cable length (to several kilometers). RS-232C is a standard communication interface for serial communication with COMLI. The CI853 supports hot swap. COMLI is an ABB protocol used for data transfer between controllers. It is designed for asynchronous master/slave communication in half duplex. The COMLI protocol supports dial-up modems controlled from an application. The CI853 supports both master and slave modes in COMLI.

MODBUS RTU is a standard protocol that has been widely disseminated for its ease of use and reliability. Modbus RTU is an open serial (RS-232 or RS-485) protocol with a source autonomous/slave architecture that exchanges information in half duplex mode. The Modbus function can be configured on the COM port of the AC 800M and CI853. Module redundancy is not available in MODBUS RTU. The CI853 supports only master mode in MODBUS RTU.

Characteristics and advantages

COMLI can be used to build the COM3 port, as well as the CI853 port. RS-232C is a standard communication interface for serial communication with COMLI. The CI853 supports hot swap. COMLI is an ABB protocol used for data transfer between controllers.

MODBUS RTU is an open serial (RS-232 or RS-485) protocol, source autonomous/slave architecture, that exchanges information in half-duplex mode. The Modbus function can be configured on the COM port of the AC 800M and CI853.

The Siemens 3964R can be used with a built-in COM3 port or optionally with a CI853 port. A standard RS-232C/485 communication channel is required.

Custom serial communication is available on the built-in COM3 port (on the AC 800M controller) and the optional CI853 port.

The CI853 module also supports hot swap.
