The CP 581 is an AT computer compatible with the industrial standard. It is fitted in
your programmable controller subrack.
It consists of hardware modules which you can combine in certain configurations:
· Basic board with 80386SL or 80486SL and with silicon disk
(as option with memory card and/or onboard silicon disk)
· Mass storage module with floppy disk drive and hard disk
· AT-slot module for insertion of a short AT board.

The CP 581 provides you with additional computing performance in conjunction with
the S5 CPU in order to solve your automation task. Direct communication with the S5
CPU via the internal S5 backplane bus enables effective data transfer between the
S5 CPU and the CP 581.
