PROFIPOWER POWER ELECTRONICS
Therefore, the maximum number of selected Modbus registers will
be 60 for the writing Scenarios and 60 for the reading Scenarios.
That is, all the registers selected for the configured writing Scenarios
do not exceed 60. And in the same way, all the registers selected for
the configured reading Scenarios do not exceed 60.
The configuration of the Scenarios will be realized in the same way
that has been explained for the Profipower Type 1 Module.
Note : When you introduce the Modbus addresses of the desired
parameters for reading and writing in the Hardware configuration of
the gateway, you should consider the following points:
ƒ
If the slave equipment is a model of SD250 or SD450
Series, the addresses will be introduced by subtracting “1”
to the value that appears in the manual of this equipment.
For example: if the address indicated in the manual is
“0x000A”, you should introduce the value “9”.
ƒ
If the slave equipment is a model of SD700 Series or V5,
you should subtract “40001” to the address indicated in the
manual of the equipment, and then you should introduce the
resultant value in the gateway configuration. For example, if
the address indicated in the manual is “40003” you should
introduce the value “2”.
ƒ
Is the slave equipment is a model of SD700 Series and it is
configured from a base address as much of reading as of
writing, you should make sure the registers that you want to
access have modbus addresses correlative to selected
base address. Consult the modbus communication manual
of the equipment for additional information.
The description of the Profibus frame will be determined by the
realized set up of the scenarios.
As well as the Scenarios, we will have to configure the parameter
“ Modbus Device ” to indicate the Modbus device that is going to be
connected to the gateway. The gateway supports the Modbus slaves
that have been enumerated in the previous section.
