Tistar can communicate with older TI PLCs such as the 520, 530,

and 560 series, and the PM550. PCS 7 cannot communicate with

these. To migrate a Tistar system with these PLCs, their logic

would have to be recreated Simatic S7 series PLCs. The old TI

PLCs would be discarded.

PCS 7 does not support SIMATIC S5 PLCs. Therefore, migrating

an OSx system that uses S5 requires that you recreate their logic on

SIMATIC S7 series PLCs. The S5 PLCs would be discarded.

SIMATIC S7 PLCs are configured through Simatic Manager which

is a standard part of PCS 7. Consult the PCS 7/505 OS Setup Guide

if you plan to include SIMATIC S7 PLCs in your PCS 7/505 OS

project.

SIMATIC TI505 PLCs are configured via DBA. This is done using

the tag files imported into DBA. The first action you need to take

when creating a project through DBA is to configure the PLCs. You

do this by informing DBA which tag files will be used to import

505 tags into you PCS 7 project. This is called “adding an AS

source node” in DBA. DBA then reads the first tag in these files

and configures the PLC to which that tag is assigned. Once DBA

knows about the PLC, you can then enter the PLC’s MAC address

using DBA. When your project is compiled from DBA to WinCC, a

505_PLC tag structure for each TI505 PLC is created.

Each CP1434TF card in a TI505 PLC has a list of the station names

and MAC addresses to which it will be communicating. It does not

have those for your new PCS 7 servers. When migrating to PCS 7,

you will have to add new associations in each CP1434TF module

to which your new PCS 7 system will be connected for each server

that will communicate with that PLC. This is done via the same H1

software you used to do this for your OSx stations.
