Program Description:
·
PLC Ladder Program of PLC_A:
PLC Ladder Program of PLC_A:
(1) The received data are stored in CR#49 ~ CR#55.
(2) The data received every one second are written into D0 ~ D6.
·
PLC Ladder Program of PLC_B:
PLC Ladder Program of PLC_B:
(1) The data exchange will be executed every one second.
(2) Write the communication address of the destination PLC in CR#28, and DVPEN01-SL will automatically detect by the previous setting that No. 1 IP is “192.168.0.4″.
(3) Write the data of RTC into CR#29 ~ CR#355.
(4) Write “1” into CR#13 to start the data exchange.
(5) CR#14 = 2 refers to exchange completed. CR#14 = 3 refers to exchange failed.
