Hi  !
I have to read aprox. 80 coil registers from each of several equips but I want to read the registers with just 1 request like I do with INT values.
I have tried with the following example (test with 4 variables) but it doesn't work !
(For reading holding registers this way works fine)
Any ideas?
Code: 123456 { "name": "Test1", "bus_datatype": "1", "type": "coil", "datatype": "bool", "address": 0, "writable": 0, "read_count": 4, "read_offset": 0, "read_swap": "n" },
{ "name": "Test2", "bus_datatype": "1", "type": "coil", "datatype": "bool", "address": 0, "writable": 0, "read_count": 4, "read_offset": 1, "read_swap": "n" },
{ "name": "Test3", "bus_datatype": "1", "type": "coil", "datatype": "bool", "address": 0, "writable": 0, "read_count": 4, "read_offset": 2, "read_swap": "n" },
{ "name": "Test4", "bus_datatype": "1", "type": "coil", "datatype": "bool", "address": 0, "writable": 0, "read_count": 4, "read_offset": 3, "read_swap": "n" }
(...)

Please change address and try again. And what is the current result? What you have in Logs, Errors, Alerts?
And here you have some post about limits:

Multiple read for coils is not supported yet, we'll look into adding it to next firmware.

Which address ?
What happens with the 4 variables I have posted is that they have the same value (from the modbus address 0).

Okay, thank you.
It will be a very very important feature to have.

Hi,
Is there any news about this feature ?
I'm testing a SL with FW 2.4.0 and is still not supported :\
Thank you

There is already much newer FW for SL, try using 2.5.1

This was never implemented, we are doing it right now.
