8.6 Initializing the R2

The R2 must be initialized when the contents of the R2 buffer memory ( R 2 0
112 ) have been changed.
H
R2 initialization refers to canceling the processes currently being carried out, and
resetting the R2 to the startup state.
The R2 initialization is carried out with the sequence program.
(R2 initialization items)
During the R2 initialization, the following processes related to communication with
the external device using the RS-232-C interface are carried out.
1) Canceling of transmission/reception process
2) Canceling of reception area clear process
3) Cancellation of transmission cancel process
4) Cancellation of forced reception complete process
5) Initialization of flow control process
6) Initialization of frame transmission/reception process
7) Initialization of control signal status
8) Initialization of OS reception area
9) Initialization of error causes, such as error LED OFF
* During initialization, the RX/RY/RW and buffer memory related to the R2
data link are not initialized.
(1) Flow of process
When setting the initialization data using the buffer memory automatic update
function, refer to section 5.5.1 (2).
When using the transmission/reception buffer to set the initialization data, refer to
section 5.5.2 (2).
(2) Timing chart
When setting the initialization data using the buffer memory automatic update
function, refer to section 5.5.1 (3).
When using the transmission/reception buffer to set the initialization data, refer to
section 5.5.2 (3).
(3) Program
When setting the initialization data using the buffer memory automatic update
function, refer to section 5.5.1 (4).
When using the transmission/reception buffer to set the initialization data, refer to
section 5.5.2 (4).
