Step Description

(1) The fixed portion of the send command is set. This processing is performed once at

startup.

(2) A communications refresh timer of 300 ms is started. This performs the first sending after

300 ms.

(3) Once 300 ms has elapsed, the RS-232C reception end bit (X0A) is checked, and receive

processing is performed if data has been received. A send command from the Standard
PLC is initially required, and so reception processing is performed after completing the

first send.
(4) To store the reception response in D100, the INPUT instruction is executed.
(5) G9SP communications reception data is set to the send command from X 100 and echo

back bit.
(6) The send command is transferred to the RS-232C send port, which enables sending to

the G9SP-series Controller.
(7) The checksum and the end code are set to the transmission command.The send

command is transferred to the RS-232C send port, which enables sending to the

G9SP-series Controller.
(8) The timer is restarted and the next receive processing is performed after 300 ms.
(9) The checksum calculation subroutine given above is called, and the checksum of the

reception response is calculated.

(10) The checksum of the reception response and the end code are checked, and the G9SP

Communications Transmission Data is copied to Y 200 and G9SP Safety Input Terminal

Data is copied to Y 220.

Reception completion processing

Step Description

(1) The fixed portion of the connection process is set. This processing is performed once at startup.
(2) The connection is open after the initialization process is completed.
(3) A communications refresh timer of 300 ms is started. This performs the first sending after 300 ms.
(4)

Once 300 ms has elapsed, the reception completion bit (M40) is checked, and receive
processing is performed if data has been received. A send command from the Standard PLC is
initially required, and so reception processing is performed after completing the first send.

(5) Set the FINS data to the sending command.
(6) Set the “G9SP communication reception data” to X100 of sending command and set the “Echo back

bit” and transfer to Ethernet port. By this flow, the sending command is transfered to the G9SP series.
(7) The timer is restarted and the next receive processing is performed after 300 ms.
(8) The ZB.BUFRCV instruction is executed because the reception response is stored to D500.
(9) The checksum of the reception response and the end code are checked, and the G9SP Comm-

unications Transmission Data is copied to Y200 and G9SP Safety Input Terminal Data is copied to

Y220.

Step Description

(1) A communications refresh timer of 300 ms is started. This performs the first sending after 300 ms.
(2) Once 300 ms has elapsed,send and receive processing is performed and the timer is restarted and

the next send and receive processing is performed after 300 ms

(3) Clear the receive area in preparation for the FC6 instruction. The reception size (#STAT15) is

checked, and receive processing is performed if data has been received. A send command from the
Standard PLC is initially required, and so reception processing is performed after completing the first
send.

(4) Once the data has been stored in the cleared receive area, check the size, and then start receive

processing.

(5) Copy G9SP Communications Transmission Data to QW 100 and QW 101 and G9SP Safety Input

Terminal Data to QW 102 to QW 104.
(6) The fixed portion of the send command is set.
(7) Once receive processing has been completed, set G9SP Communications Reception Data to the

send command from IW 100. The send command is sent to the Ethernet send port, which enables

sending to the G9SP-series Controller.
