Caution:
When upgrading the bridge system software care must be taken that the bus coupling module TPM478 is version 5 or later, otherwise all error corrections will not be effective.
4 Extended Functions
Installing the new M7 - CPU 486-3:
From V02.00, the BRIDGE system software runs not only on the CPU 488-4, but also on the new CPU 486-3. The changes to the order configuration are described in detail in the PLT 112 catalogue (1998 version).
The CPU 486-3 replaces the CPU 488-4. In contrast to the CPU 488-4, the CPU 486-3 has only two module ports for interface modules instead of three.
Caution: A memory card upgraded from V01.03 to V01.05/V01.06 will not run on the CPU 486-3. For this CPU, either an original delivery of V02.xx has to be used, or an upgrade to V02.01 has to be done.
Replacing the CP5412-A1 with an IF964-DP interface module:
Now, not only the CP5412-A1 module (in the AT adapter card ATM 478) can be used as a bus circuit for the PROFIBUS-TM system bus, but an IF964-DP interface module in an EXM 478 extension module can also be used. The extended configuration is described in Chapter 6.3 of this product information.
The configuration file L2AMPRO.INI (for the IF964) takes precedence over the parameter file DOS_CONF.DAT (for CP5412-A1). In order to maintain the previous bus configuration when updating, the new INI file is supplied as L2AMPRO.INX on the update diskette. The file should be renamed accordingly if an IF964-DP is to be used. The file L2AMPRO.INI is supplied as standard on the memory card with new deliveries of version V02.xx .
With new deliveries of version V02.xx, the PROFIBUS-TM system bus is accessed with the interface module IF964-DP as standard, which is operated in the EXM 478 extension module. This replaces the previous configuration with the CP5412-A1 bus coupling in the ATM 478 extension module.
