2. Address Configuration: Each Modbus device on a single network must have a
unique address. Set the switch block to assign a unique address before the device
is connected to the Modbus RS-485 network. If an address is selected which
conflicts with another device, neither device will be able to communicate.
3. The E30 uses two logical addresses. Panel 1 uses the base address as set on the DIP
switches, and Panel 2 uses this base a 1. Address the E30 as any whole
number between and including 1-246. Each unit is equipped with a set of 8 DIP
switches for addressing. See below.

4. To determine an address, simply add the values of any switch that is on.
For example:
40
=
LSB
MSB
Switch number 4 has an ON Value of 8 and switch number 6 has an ON Value of 32.
(8 + 32 = 40). Therefore, the address for Panel 1 is 40, and the address for Panel 2 is
41.
See the Address Setup section (page 8) for a pictorial listing of the first 63 switch
positions.
