Reception processing of a ReinitializeDevice service
When the reinitializeDevice checkbox is selected
*1
in the ProtocolServicesSupported property of the Device object of a
BACnet module, a Reinitialize processing is performed with the following process after receiving a ReinitializeDevice service
(ColdStart or WarmStart).
*1 The checkbox is selected by default.
For the setting method, refer to the following section.
Page 257 Setting the ProtocolServicesSupported property of a Device object
■ CheckYDevice in the BACnet detail setting is '0'
■ CheckYDevice in the BACnet detail setting is '1'
Operation of a BACnet module X0 X1 X2 Remarks
BACnet communication is in operation. 111In operation
A ReinitializeDevice service is received.
The BACnet module responds to the ReinitializeDevice service,
and BACnet leaving processing is performed.
A SimpleAck is returned as a response.
After the module has left from BACnet, the value of X2 is changed
to '0'.
10
The value of X1 is changed to '0'. 100
The operation of the module is stopped. 0
The value of X1 is changed to '1' to restart the module. 01
BACnet joining processing is started. 1
After the module has joined to BACnet, the value of X2 is changed
to '1'.

Change the value of X1 to '0' to
inform the program to stop the
operation.

0 After the value of X1 is changed
from '1' to '0', the value of Y1 should
be changed to '0'.

The value of X1 is changed to '1'. 01 The change of the value of Y1 from
1 to 0 works as a trigger.
1 After the value of X1 is changed
from '0' to '1', the initial value is
written to the buffer memory.
After the initial value is written, the
value of Y1 is changed to '1'.
