Hi,

I am trying to read 208 addresses but the mobus node only shows me in the message node the info about 125 address quantity.

How I can to read the 208 addresses with node red? Thanks and regards.

You can't. I won't go into why (but [there is a thread](https://discourse.nodered.org/t/how-to-create-an-modbus-tcp-alarm-status-dashboard/43041/12) on this forum that covers this). Do 2 consecutive reads instead.
