CI871 and TP867 – PROFINET IO Interface
Key Features
• Provides one 10/100 Mbps fast Ethernet port
for PROFINET IO (RJ45 connector located
on the TP867 base plate).
• Simple DIN-rail mounting.
• Provides communication with PROFINET IO
protocol through Ethernet with 100 Mbps.
• Preset, two letter Alpha code locking device
installed in the unit base, which prevents
mounting of incompatible components.
• Supports hot swap.
Description
The CI871 can be used to connect an AC 800M
controller to PROFINET IO devices.
The TP867 Baseplate has two RJ45 Ethernet
connectors. CH1 connector supports 10 Mbps or
100 Mbps. CH2 connector supports only 10 Mbps.
The Ethernet cable must be connected to the PROFINET IO network through an
Ethernet switch. The baseplate has a code lock (refer Table 4 on page 75), which
prevents the installation of an incorrect type of unit onto the TP867 baseplate.
The CI871 expansion unit contains the CEX-Bus logic, a communication unit, and a
DC/DC converter that supplies the required voltage from +24 V supply through the
CEX-Bus.
By default, the CH1 connector is used in PROFINET IO as it supports 100 Mbps.
