Device Communication Control Password:
Configures the password to request when the Device Communication Control service is received
from a BACnet device. The maximum number is 20 characters. When the Device Communication
Control service is received, the MICRO/I does not initiate a service or provide a response for the
specified period of time.
Unsubscribed COV Frequency (sec):
Configures the cycle to regularly provide notifications of property values with the COVU function
as 1 to 65,535 (seconds). If 0 is set, the COVU function is stopped, and notification is provided
only when there is a change in the target property.
Fixed Value: Use a constant value. (Default: 60 sec)
Data Register: Uses a value of device address.
• Only one Unsubscribed COV frequency can be set for the MICRO/I, and different frequencies cannot be
set per object.
• Whether or not to use the COVU function can be selected per object. The COVU function can also be
enabled and disabled by specifying a data register and changing its value.
• When changing the value of the data register, the Unsubscribed COV frequency after it has been changed
will be applied after the service is next initiated.
Enable Foreign Device: Configures whether or not to use the Foreign Device function.Using the Foreign Device
function, the MICRO/I registers itself as a Foreign Device on the configure BBMD.
BBMD IP Address: To join a BACnet/IP network when there is no BBMD on the IP subnet of the MICRO/I,
configures the IP address of the BBMD on the other IP subnet.
Fixed Value: Use a constant value.
Data Register: Uses a value of device address.
This option uses 4 words of address numbers starting from the specified
data register.
Example: Configures 192.168.2.5 to the IP address of the BBMD.
The address number of Top Device Address+0 = 192
The address number of Top Device Address+1 = 168
The address number of Top Device Address+2 = 2
The address number of Top Device Address+3 = 5
BBMD Port Number: To join a BACnet/IP network when there is no BBMD on the IP subnet of the MICRO/I,
configures the port number of BBMD on other IP subnet from 1 to 65,535.
Fixed Value: Use a constant value. (Default: 47808)
Data Register: Uses a value of device address.
Lifetime (sec): Configures the interval of time to register the MICRO/I with the BBMD as a Foreign
Device in the range from 0 to 65,535 (seconds). (Default: 360 sec)
When (Lifetime + 30) sec has elapsed from registration, the registered content will be
deleted from the BBMD.
Registration Trigger Device: The device address used to register the MICRO/I with the BBMD configure with BBMD
IP Address above as a Foreign Device. When the value of the Registration Trigger
Device is changed from 0 to 1, the MICRO/I is registered with the BBMD. To
continuously register the MICRO/I with the BBMD, use the Registration Trigger
Device to re-register the MICRO/I before (Lifetime + 30) sec elapses.
