Write a general mode parallel link communication program
Two FX2N series PLCs exchange data through a 1:1 parallel link communication network, designing one
General mode communication program. The communication operation requirements are as follows.
(1) The ON/OFF status of the master station XOOO to X007 is output to the slave station through M800 to M807.
YOOO—Y007.
(2) When the calculation result of the master station (DO+D2) ≤ 100, the YOIO of the slave station changes to ON.
(3) The ON/OFF status of the MO to M7 in the slave station is output to the master station through MOOO to M007.
YOOO～Y007.
(4) The value of the slave D10 is used to set the timer (TO) value of the master station.
Solution: Set the program of the master station and the slave station according to the requirements of the topic, as shown in Figure 6-25. Figure 6-25 (a)
Set as the master station, complete the XO ~ X7 state input, (DO + D2) operation, status output, and
Timer operation settings. Figure 6-25 (b) is the slave setting, respectively, the output setting and comparison operation are completed.
And the timer setting and other operations.
