The
Node_Name
is the name entered below and refers to the unique combination of the
Node_ID
and
Port
.
The
Address
is the starting address of the Modbus RTU device. The different address ranges
refer to different input and output types (see the Modbus protocol for details). The
Length
refers to the number of data points to be read from the device. The
Scan_Interval
is the
speed at which we wish to read the values from the device.

Node_Name
is used below to get and set data from the device. The
Node_ID
is the user
assigned Modbus RTU address of the device.
Port
refers to the port on Blue Heat/Net.
P1
is
serial 1, etc.
Note:
It is possible to have more than one
Node_ID
on a single port. It is also possible to have
different nodes tied into different ports but have the same
Node_ID
.
