SIMATIC PCS 7 cabinet design
AS 488/TM system unit
■ Overview
The scope of delivery of the AS 488/TM is variable, and is de-
fined specific to the order.
Fundamental components of the AS 488/TM are:
• Mounting board for the UR2 rack and the rail for the OLM opti-
cal link module
• AS 488/TM CPU, comprising:
- SIMATIC M7 CPU 486-3 or CPU 488-3
- Memory module set with 2 x 8 Mbyte
- UR2 rack (9 slots)
- IF 962-COM serial interface module for commissioning termi-
nal with two RS 232 interfaces
- IF 961-DIO interface module for I & C monitoring functions
- AS 488/TM system software on 8-Mbyte memory card
- Commissioning terminal software on 3.5-inch diskette
• PROFIBUS-DP connection for distributed I/Os via EXM 478 ex-
tension module, as electrical or optical design. The compo-
nents for a second PROFIBUS-DP line must be ordered
separately.
• Components for connection to the CS 275 or PROFIBUS-TM
system bus, components for PROFIBUS-TM as electrical or op-
tical design.
• DC 24 V or AC 120/230 V power supply: depending on the in-
put voltage, the AS 488/TM can be equipped either with a
PS 407 power supply module (AC 120/230 V supply) or a
PS 405 power supply module (DC 24 V supply), each rated at
10 A. These supply the AS 488/TM modules with the DC 5 V
and DC 24 V operating voltages via the backplane bus. The
PS 405 and PS 407 power supply modules also contain the
backup batteries for buffering the time and date.
• Supplementary system documentation consisting of a manual
for AS 388/TM, AS 488/TM and CS-L2 bridge in German or En-
glish.
