Migration of existing systems

Migration packages

MIG I migration rack

The migration racks are the core components of the AS 488 S and AS 488 K migration packages. They integrate the

AS 488/TM automation systems as replacements for existing ba- sic units/systems in an existing TELEPERM M system environ- ment.

The following migration racks are available:

•MIG I migration rack

for AS 488 S (without slots for TELEPERM I/O modules)

•MIG II migration rack

for AS 488 S (5 slots for TELEPERM I/O modules)

•MIG K migration rack

for AS 488 K (5 slots for TELEPERM I/O modules)

■Overview

The MIG I migration rack is a subrack of the ES 902 packaging system with assembled SIMATIC S7-400 backplane bus and connection units. It is provided for conversion of existing cabi- nets of the AS 220 S, AS 230 and AS 235 automation systems into an AS 488/TM system.

The migration rack has the same dimensions as the basic unit of the automation systems, and replaces this in an AS cabinet. Ex- isting extension systems with installed I/O modules can still be connected to the migration rack and used with it.

The migration rack contains a guide for preassembled cables as well as a fuse for L+ 24 V/16 A.

The MIG I migration rack has no slots for I/O modules. When us- ing this migration rack for conversion of a TELEPERM M automa- tion system into an AS 488/TM, the I/O modules inserted in the AS basic unit must therefore be converted into an extension unit or an additional ES 100 K extension system. A prerequisite, however, is that sufficient slots are still available there for these I/O modules.

2 plugs are located at the rear of the migration rack for connec- tion of the I/O buses A and B using the existing ribbon cables.

In the migration rack, the TPM 478 module processes up to two I/O buses (A and B) with a maximum of 8 extension

units/ES 100 K extension systems via the TBX 478 module.

The following assignments are possible per I/O bus:

• 3 extension units and one ES 100 K extension system

• At least 1 extension unit and up to three ES 100 K extension systems

• Up to 3 extension units in the basic cabinet, or up to four exten- sion units in the extension cabinet of an AS 230 or AS 235 sys- tem. The ribbon cable must be replaced when using 3 or

4 extension units for AS 230.
