Description

The AC500’s system architecture
CPUs
CPUs are available in the performance classes PM571,
PM581 and PM591, can all be programmed in five
different languages, and provide an LCD display, an
operator keypad, an SD card slot, andtwo
integrated serial interfaces. The CPUs can be
simply plugged onto the CPU terminal base.
Optionally,
they are also available with integrated Ethernet
or ARCNET.
The CPU terminal base
Available in three different versions, enables
easy plugging of the CPU and one, two or four
communication modules.
The I/O modules
Digital and analog in different versions.
Can be simply plugged onto the terminal units
– for local expansion of the CPU (max. seven
modules) and decentralized expansion via the
FBP interface. Flexible use thanks to configurable
channels.
The terminal units
Multi-purpose usage for both digital and analog
I/Os, for 1, 2 and 3-wire designs. Enable simple
prewiring without electronics. For 24 V DC and
230 V AC, optionally for spring or screw-type
terminals.
The communication modules
For connection to standard field bus systems
and integration into existing networks. Up to
four communication modules in any desired combination
are allowed at one CPU, resulting in a high degree of communication.
The FBP interface module
With embedded digital I/Os and a field-bus-neutral interface for connecting the
chosen FBP connector. For decentralized expansion by up to seven I/O modules.
The SD card
Optional for data logging, downloading and uploading the user program without a
PC or a firmware update for all devices (CPU, couplers or I/O modules).
