Address Switch
Address Switch
Address setting via EE-PCS Product Configuration Software:
All Dip-Switches at position 0 → address has to be set via Product Configuration Software
Modbus
(Slave device): factory setting EE650: 65 (permitted values: 1…247).
BACnet
(Master device): factory setting EE650: 65 (permitted values: 0…127).
Example: Slave address is set via configuration software.
Address setting via Dip-Switch:
Modbus
(Slave device): Setting the Dip-Switch to any other address than 0, overrules the slave
address set via configuration software (permitted values: 1…247).
BACnet
(Master device): Setting the Dip-Switch to any other address than 0, overrules the slave
address set via configuration software.
BACnet Note:
permitted values are 0…127. The 8th bit of the Dip-Switch is ignored
(ID 127 = 0111 111).
To set address 0 via Dip-Switch, the 8th bit shall be set to 1 (ID 0 = 1000 0000).
Example: Slave address set to 11 (= 0000 1011 binary).

Wiring
Hardware
The bus termination shall be realized with 120 Ohm resistor, switch on the board.
Very important:
For proper function the power supply must be strong enough to ensure supply voltage within the specified range (see technical data)
at any time and at all devices in the bus. This is particularly relevant when using long and thin cables which can cause high voltage
drop; please note that a single EE650 requires peak current of 150 mA.
