Connecting TELEPERM M I/Os

■Overview

In existing TELEPERM M systems, AS 220 S, AS 230, AS 230 K, AS 235 or AS 235 K automation systems are replaced by migra- tion with AS 488 S (cabinet design) or AS 488 K (compact de- sign). System integration is carried out in each case using so- called migration racks (MIG I/MIG II for AS 488 S or MIG K for AS 488 K). The migration rack together with the TPM 478 and TBX 478 interface modules also comprises the interface to the TELEPERM M I/Os in the extension units of the TELEPERM M cabinets and in the ES 100 K extension systems. Data exchange is via the I/O buses A and B of the TBX 478 interface module.

As with the AS 230 / AS 235, up to three expansion units in the basic cabinet as well as an external ES 100 K can be operated on the I/O bus A of an AS 488 S. Following replacement of the ribbon cable for the I/O bus, up to four extension units of an AS 230 / AS 235 extension cabinet can be connected via the I/O bus B. When carrying out migration with AS 488/TM it is therefore possible to add a fourth extension unit to an AS 235 ex- tension cabinet of maximum configuration. There is therefore no limitation with respect to the number of migratable I/O modules for an AS 230 / AS 235 configured with the maximum number of TELEPERM M I/O modules.

The AS 488 K with its MIG K migration rack has a design equiv- alent to that of an AS 235 K. The MIG K migration rack has five slots for TELEPERM M I/O modules. 2 x 4 compact ES 100 K ex- tension systems can be connected via these 5 slots using the serial coupling known from the AS 235 K. These extension sys- tems can be located up to 500 m away from the AS 488 K auto- mation system, and are therefore highly suitable for a distributed design.

The TPM 478 interface module additionally permits connection of an AS 488/TM system to the CS 275 bus system. However, the AS 488/TM automation system must not be connected simulta- neously to the PROFIBUS-TM bus system.

TBX 478 interface module

The TBX 478 interface module together with the TPM 478 inter- face module links the I/O modules of the TELEPERM M system to the AS 488/TM system.

The following interfaces are present on the TBX 478 module:

•Interface to the TPM 478 module for implementation of the two TELEPERM M I/O buses A and B

•2 remote interfaces connected via cables:

-for connecting the I/Os in the basic cabinet (I/O bus A) and extension cabinet (I/O bus B), with incorporation of the I/O slots of the MIG II migration rack (cabinet design) or

-for connecting the I/O slots of the MIG K migration rack to I/O bus A and I/O bus B (compact design)

•Interface for "+5 V bus" for power supply to TELEPERM M ex- tension units (cabinet connections)

•Interface to the backplane bus for power supply to the

"+5 V bus" from the power supply module of the automation system.

The TBX 478 module need not be parameterized. It is provided with data from the TPM 478 module.

The configuration parameters for the I/O area are defined using the PROGRAF AS+/NT configuration tool and the SYST.WART maintenance component, and subsequently saved permanently on the memory card. The new or modified parameters are acti- vated when recalled.

Two sets of ribbon cables are available for assigning the 5 I/O slots of the MIG II migration rack to I/O buses A and B. The as- signment of the 5 I/O slots of the MIG K migration rack to

I/O buses A and B is fixed, and cannot be changed.

A list of the TELEPERM M I/O modules which can be operated with the AS 488/TM automation system is available on the Inter- net.
