Note for S7-CPUs
The following S7-CPUs are considered to be “older”: S7-400 CPUs with firmware < V3.0
and S7-300 CPUs with firmware < 2.0 or CPUs, where no firmware version is indicated
in the hardware configuration.
In general, S7-CPU of the older type do not support long slots with the setting “Consistent
over total length”. When configuring those slots,
no
error message is generated in Step 7.
In this case, use the universal module with the setting “Consistent over unit” for the ibaBM-
DP configuration.
When using CP443-5, there are also restrictions regarding the max. slot length when
“Consistent over total length” is set. For more information, please see the according mod-
ule manuals.
When using S7-CPUs of the older type, the max. slave address length may also lead to
restrictions. Some models support only a maximum slave length of 122 Bytes. Usually an
error message occurs when the device is being configured.
11.3 Operation with outputs
If you want to use outputs in ibaPDA, the PROFIBUS configuration of the master needs
to have an appropriate range of input data. Please use the slot modules for inputs in the
GSD file.
In the following example, a total of 244 Bytes of input data have been configured with 2
slot modules with a length of 122 Bytes each for slave 21.

Exactly as for the outputs, the maximum length of the input range is also 244 Bytes.
