I've been trying to build a Modbus TCP communication link between a Raspberry PI and my Victron CCGX system. As a result, Raspberry Pi should work as a Master in order to read data from the Victron system.
As such, I want to use Raspberry PI "Modbus TCP/IP Master Read" block in Simulink and automatically generate the code. It turns out that this block does not allow user to specify Unit_ID parameter of the Modbus TCP/IP protocol which is required by Victron devices.
Does anyone know if this parameter can be specified within the extarnal code of Modbus TCP/IP block in one of the Raspberry PI libraries? Is it possible to assign it according to my requirements?
Best Regards,
Bartosz
