AS 488 in SIMATIC design

Packaging system

■Overview UR2 rack

The UR2 universal rack is the mechanical support for the AS 488 automation system. It accommodates the system modules (CPU, load power supply, EXM 478, TPM 478 and TBX 478), provides the modules with operating voltages, and links the in- dividual modules via the backplane bus.

The rack comprises:

•Aluminium support rails with threaded bolts for securing the modules, and cut-outs at the side for assembly of the rack

•Plastic parts as guide when swinging in the modules

•Connection for protective earth conductor

•Backplane bus with plug connectors.

Migration rack

An AS 488/TM system can be installed in an existing TELEPERM M cabinet by using an MIG I or MIG II migration rack.

The MIG I migration rack (simple version) is designed using 19" technology and equipped with the SIMATIC S7-400 back- plane bus to accommodate the AS 488/TM system modules (power supply, CPU and interface modules). Its dimensions cor- respond to those of the basic subrack of the TELEPERM M auto- mation system to be migrated, and can be fitted instead of the latter in the TELEPERM M cabinet. Existing extension units with TELEPERM M I/O modules can be connected using ribbon ca- bles.

The MIG II migration rack (extended version) is also designed using 19" technology, and integrates the AS 488/TM system modules in the same manner as the MIG I migration rack. It ad- ditionally contains 5 slots for I/O modules which can be option- ally set for slot addressing. As with the AS 235, these I/O slots are wired using wire-wrap connections at the rear. Existing ex- tension units with TELEPERM I/O modules are connected to the rear of the right-hand migration rack panel using ribbon cable in- terfaces for I/O buses A and B.

The ability to accommodate up to 5 I/O modules and to set slot addressing for these modules means that the MIG II migration subrack is the first choice for migration of TELEPERM M automa- tion systems.
