3.5.3 Deviations from the standard HPU configuration
(up to SW 3.1)
The following documents are also required:
References: /BH/ Operator Components Manual
/FB/, P3, Basic PLC Program
/S7HT/ Manual, Application of Tools
The following features are examples of deviations from the standard configura-
tion:
S Changes to the address assignment
of the input, output or status bytes,
or flag area or data block
S Additional connection of an MCP
An example is given using the following configuration:
– PLC–CPU AS314
– MCP
– HPU
You must adjust the communication parameters and possibly the switch settings
(addresses) of the bus nodes.
To set a new configuration, first press the Define global data softkey. The fol-
lowing description of how to proceed is based on the assumption that you are
already familiar with this menu.
1. Set up a new project and CPU programs with the STEP7 tool. You must set
up a CPU program for each component of the system (PLC, MCP, HHU, 2nd
MCP, HPU...).
2. Network MPI nodes, i.e. network CPU programs with MPI address.
3. Call “Global data” menu (via File manager / MPI network / Options /
Global Data softkeys) and enter the desired configuration.
4. Compile this configuration. A new SDB is generated for each CPU program.
5. Set the cyclical transmit pattern. Once the configuration has been compiled
successfully for the first time, the “Reduction ratio” and “Status” can be acti-
vated and then input.
6. Compile your configuration again.
7. Transfer the SDB (from the CPU program of the PLC) to the PLC.
8. Call FB1, DB7 must be parameterized for all operator control components
(MPI nodes) in OB 100 in the basic PLC program.
9. The status pointer (double word) must be configured in FB1 for each compo-
nent for monitoring purposes.
