Technical data

General procedure:
To implement a simple task (transferring data from PLC 1 to the remote
device via pre-programmed links with HDBs) the following procedure is
required:
➣
The links between the PLC and remote device must be programmed
(as mentioned in the general guidelines). For planning the link, refer to
Characteristics of the S5-S5 Link.
➣
Assigning parameters to the CP module. This involves creating the
SYSID block (refer to Chapter 6)
➣
Configuring the links between the PLC and the remote device.
➣
Programming the CPUs of the PLCs i.e. HDBs, OBs, FBs and DBs and
creating the frames with service-specific headers (refer to Section 8.1)
according to the planned task..
8.3.1 Configuring Free Layer 2 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.
These links are either stored in a submodule file (offline mode) or written
directly to the CP submodule or modified there (online mode).
This means that submodule files created offline can also be loaded on the
CP or that the contents of the CP submodule can be saved in a file.
