4.3. Configuration and Set up.
4.3.1. Profipower Type 1 module.
It is a generic module that allows 5 output registers and 5 input
registers.
To configure this generic module, we will define the parameter
“Scenario” . The Scenarios are the Modbus frames that we want to
send.
Each Scenario is completely defined with a base address of Modbus
register and a number of Modbus registers from this base address.
This determines the Modbus registers block to be read or written.
If base address is 40000, and 5 registers can be written, the
scenario can be configures with the address 40000 and the position
5. This allows writing in the addresses from 40000 to 40004, all
consecutive. This is also valid for the reading function.
For this module it can be defined up to 10 Scenarios, such as it has
been indicated above. These Scenarios are 5 for the write command
and the other 5 are for read command. This is a generic module
and, therefore, it is independent of the equipment connected to the
gateway. For this reason, user will be responsible of the knowledge
of the valid Modbus registers for the equipment that is going to be
connected.
Thanks to this, the registers can be alternate or random instead of
consecutive. In this way, for example, if you want to write in the
registers 40000, 40008, 40012, you should configure 3 writing
scenarios: the first one with the address 40000 and the position 1,
the second one with the address 40008 and the position 1, and the
third one with the address 40012 and the position 1. So, it is being
indicating from each position it only will be written 1 register (the
indicated one).
