Technical data

General procedure:
To implement a simple task (transferring data from PLC 1 to PLC 2 via
pre-configured links with HDBs) the following procedure is required:
➣
The links between the PLCs must be configured (as mentioned in the
general guidelines). For planning the link, refer to Characteristics of the
S5-S5 Link (Section 7.2.1).
➣
Assigning parameters to the individual CP modules. This involves
creating the SYSID and INIT blocks (refer to Chapter 6).
➣
Configuring the links between the PLCs. This involves creating the link
blocks (refer to Section 7.1) according to the planned task.
➣
Programming the CPUs of the PLCs according to the task. This
involves HDBs, OBs, FBs and DBs.
7.2.1 Configuring S5-S5 Links
With the link editor of the COM 5430 TF/COM 5431 FMS software package
you assign parameters for the links between two stations on the bus. You
can also generate default S5-S5 links valid throughout the network (refer to
Section 6.5.4.4).
