ABB CI871
The ABB CI871 module is a communication and expansion module for industrial automation. It is mainly used to communicate in wired or wireless networks, in particular supporting Profinet IO interface 1. In addition, the ABB CI871 module can also be used as an output
expansion module for expanding the output channel in a PLC (programmable logic controller) or DCS (distributed control system) to monitor the status of external equipment 2.
Product parameters:
Communication protocol: Support PROFINET IO communication protocol, which is a widely used in the field of industrial automation Ethernet communication protocol 23.
Communication speed: CH1 communication speed is supported and can be selected between 10 Mbps and 100 Mbps. These speeds are defined in the IEEE 802.3u 10/100 Base-Tx standard 13.
Status indicator: When the module is running properly, the status indicator is green. If an abnormal fault occurs, the indicator will turn red
