Expansion with XI/ON modules

The following XI/ON base modules can be connected directly to

the XC-ADP-XION base module:

• Modules with tension clamp connection

• Modules with screw connections without C rail

Bus refreshing modules and power feeding modules cannot be

connected directly.

XC-POW50-UPS/XC-POW50-XION-UPS power supply

modules

General

A base module and a power supply module form one unit. The

following table shows the combination possibilities of both

modules. The only difference between the modules is their expan-

sion capability with XI/ON modules.

Task

The modules convert the 24 V DC power supply to +5 V DC,

+12 V DC and –12 V DC (for XC-POW50-XION-UPS) supplies, and

provide the voltages for the function modules via the PC/104+

bus. The XC-POW50-XION-UPS power supply module also

provides a 5 V DC supply to XI/ON modules via the XI/ON module

bus.

As the XC600 controller is PC-based, it must be ensured that the

program is closed and the operating system shut down properly

before the device is switched off. The supply of the power supply

module must therefore be backed up by means of an uninterrupt-

ible power supply (UPS). If the supply voltage drops, the UPS sends

a Power Fail signal to the PLC which then initiates a shutdown of

the system. The UPS unit will then keep the output voltage

constant for at least two minutes in order to ensure the trouble-

free completion of the shutdown.

Setup

The module contains a board with the PC/104+ bus. Another

board provides the interface for the XI/ON modules and connects

the power supply module with the base module.

Engineering

XC-NET-DP-M PROFIBUS-DP module

General

The module provides the interface between the CPU module and

the PROFIBUS-DP bus that is compliant with industrial standard

EN 50170 Vol. 2.

Task

The module provides the master function for PROFIBUS-DP. It

organises and operates the data exchange between the user

program and the connected slaves. Up to 31 slaves can be

connected to one line. Several sections can be connected together

using repeaters, enabling up to 125 slaves to be connected.
