@ESP_alisitsyn,
Any update on when this feature can make it into the MASTER tree?

I'm implementing a TCP modbus slave with a very sparse register map and it would save mamory to be able to have several areas of each type

@jas39_,

Unfortunately I can not provide the concrete date for this feature. It is in my todo list and will be implemented after higher priority tasks.

Could you tell me little bit more about your application? Is this Modbus master TCP or slave?

in my case it is a Modbus TCP slave (server).
The problem is, that the prepared library from esp-idf does not allow several areas of holding register areas.
