MMS6831 RS485 总线访问连接 通讯接口模块

Description

产品介绍

通讯接口模块MMS6831的功能是通过RS485总线访问连接在总线上的MMS6000模块，同时将接收到的特征值数据和报警及模块状态数据转换成标准RS232标准连接到与之相连的组态计算机，也可以通过RS485总线与DCS、DEH等系统相连并调用显示。

通过MMS6831可对连接的MMS6000模块进行组态设置。RS485总线输入 / 输出是通过模块后面的48芯插座连接的，RS232接口为6芯圆形接口，位于模块的前面板上，使用专用电缆连接。

Applications:

The function of the communication interface module MMS6831 is to access the MMS6000 module connected to the bus through the RS485 bus, and convert the received characteristic value data, alarm and module status data into standard RS232 standard and connect to the connected configuration computer. It can also connect with DCS, DEH and other systems through RS485 bus and call display.

The MMS6831 allows you to configure the connected MMS6000 module. The RS485 bus input/output is connected via a 48-pin socket at the back of the module, and the RS232 interface is a 6-pin circular interface located on the front panel of the module and connected using a dedicated cable.

RS485 input.

Data output mode: RS232 to PC; RS485 to DCS.

It can transmit characteristic values, module waveform data, and physical quantities such as module status and alarm status.

Standard card for 19 “frame.

This interface card can be used to configure the MMS6000 module connected to the bus.

Redundant power input.
