Setting the EC-Multi-Sensor Series' Subnet ID
Address
Each EC-Multi-Sensor connected to a controller's Subnet Port must be set to a unique subnet
ID address. This address should correspond to the block number of the associated Multi Sen-
sor block in EC-
gfx Program. The address is set through the rotary selector located next to the
Subnet Port connector.
Figure 56: Setting the EC-Multi-Sensor Series' Subnet ID Address
Use a small screwdriver (for example, a precision or jeweler's screwdriver) to set the selector.
Figure 56 shows an example of how to set the EC-Multi-Sensor Series' Subnet ID address DIP
switch to 1 and the EOL termination is ON.
Once an EC-Multi-Sensor is installed, the following tip can be used during system
commissioning to verify if the EC-Multi-Sensor is set to the correct subnet ID
address for the zone in which it is physically located.
Run EC-
gfx Program in debug mode for the controller with 4 Multi Sensor block
instances, 1 to 4. Set a remote control to zone ID 0, then aim it at the EC-Multi-Sen-
sor and press a command (fan speed button for example). In EC-
gfx Program, see
which block instance shows an output (RemoteFanSpeed).
Usually it is easier to reassign Multi Sensor block numbers in EC-
gfx Program code
than it is to change the Subnet ID Address of an installed EC-Multi-Sensor.
