Hi,
when I read like 150-200 registers from a modbus TCP fire-central but often some registers weren't read.
This central returns an error if I try to read more than 20 registers at once.
I saw that my HL reads registers one by one, so I think that the fire-central have a small buffer and sometimes it lost some request.
If I use "read count" mapping field, can it resolve this problem? And I don't understand how to use this mapping field, can someone explain it?
PS: The registers that I would read are not always contiguous.
