CI871

CI871K01

CI871A is an AC 800M communication interface connected to PROFINET IO devices via Ethernet. The TP867 substrate has two RJ45 Ethernet connectors, but only the CH1 connector that supports 100Mbps is used for PROFINET IO connections. The Ethernet cable must be connected to the PROFINET IO network through the Ethernet switch. The CI871 extension unit contains the CEX bus logic, the communication unit, and the DC/DC converter, which supplies the desired voltage from a +24 V power supply via the CEX bus. The CI871A module is only applicable to System 800 XA 6.0.3.3, 6.1.1 and later versions

Communication interface refers to the interface between the central processing unit (CPU) and standard communication subsystems. For example, RS232 interface. RS232 interface is a serial port, 9 core socket in the rear of the computer case, usually have a “| | O | O” beside the sample logo.
