1.7.5.2.1 Intended purpose
The PROFINET communication interface modules CI501-PNIO and CI502-PNIO are used
as communication interface modules in PROFINET networks. The network connection is per-
formed by Ethernet cables which are inserted in the RJ45 connectors in the terminal unit. An
Ethernet switch in the communication interface module allows daisy chaining of the network.
For usage in enhanced ambient conditions (e.g. wider temperature and humidity range), a
special XC version of the device is available.
1.7.5.2.2 Functionality
The communication interface module contains 22 I/O channels with the following properties:
● 4 configurable analog inputs (2-wire / single-ended) or 2 configurable analog inputs (3-wire /
differential) (1.0...1.3)
● 2 analog outputs (1.5...1.6)
● 8 digital inputs 24 V DC in 1 group (2.0...2.7)
● 8 digital outputs 24 V DC, 0.5 A max. in 1 group (3.0...3.7)
The inputs/outputs are galvanically isolated from the PROFINET network. There is no potential
separation between the channels. The configuration of the analog inputs/outputs is performed
by software.

1.7.5.2.3 Connections
The Ethernet communication interface module CI501-PNIO is plugged on the I/O terminal unit
Chapter 1.5.1 “TU507-ETH and TU508-ETH for Ethernet commu-
nication interface modules” on page 122
. Properly seat the module and press until it locks in
place. The terminal unit is mounted on a DIN rail or with 2 screws plus the additional accessory
for wall mounting (TA526
