ABB AC500 PLC - 1.7.6.5.1 Intended Purpose; 1.7.6.5.2 Functionality; 1.7.6.5.3 Electrical Connection

1.7.6.5.1 Intended Purpose
The PROFINET I/O bus module CI506-PNIO provides 2 onboard serial interfaces and 1 CAN-
open master interface. The network connection is performed via 2 RJ45 connectors which are
integrated in the terminal unit.
The bus interfaces are electrically isolated from the Ethernet network.
For usage in extreme ambient conditions (e. g. wider temperature and humidity range), a spe-
cial XC version of the device is available.

1.7.6.5.3 Electrical Connection
The Ethernet Bus Module CI506-PNIO is plugged on the terminal unit TU520-ETH Ä Chapter
1.4.5 “TU520-ETH for PROFINET Communication Interface Modules” on page 161. 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
Ä Chapter 1.8.2.4 “TA526
- Wall Mounting Accessory” on page 1152).
The electrical connection of the power supply voltage is carried out using the 6 terminals and
the 3 removable connectors of the terminal unit. The CI506-PNIO can be replaced without re-
wiring the terminal units.
