If you are using the device memory monitor function in GX Works2,You need to open your program with GX Works2 software, click on a device, right click, select “Device/Buffer Memory Batch Monitor” in “Online”, or find “Online” on the menu bar, select “Monitor” “Device/buffer memory batch monitoring”
1, need programming software, GX Developer 8.86Q
2, need to programme cable usb-sc09-fx.
Connect the programming software and PLC with the programming cable, online transfer settings (COM port settings) PLC read check the program + parameters, click to execute. You can
1. In the GX-Develop (programming interface) menu, the “Display” drop-down – comment display, make sure all comments can be seen, then click on the “Device Comments” in the leftmost project bar, double-click “COMMENT” “All the uncommented X, Y, and M devices have been commented out. You can add them after you need to fill in the comments. You can see them by closing them back to the programming interface.” – This method is suitable for batch comments
2. On the programming interface menu bar, find the “Comment Edit” button, click on the double-click on the device you want to edit, and type it, but if you want to continue programming, you need to click this button again to return to the programming state.
Timer: T0-T199 (200 points) is a 100 ms timer (set value: 0.1-3276.7 S); T200-T245 (46 points) is a 10 ms timer (set value: 0.01-327.67 S); T246-T149 (4 points) is a 1 mS cumulative timer (set value: 0.001-32.767 S, power loss retention, i.e. interruption); T250-T255 (6 points) is a 100 ms timer (set value: 0.01-327.67 S); Cumulative timer (set value: 0.1~3276.7 S, power loss maintenance, that is, interrupt action).
If T192-T199 and T246-T249 are used in subroutines or interrupt programs, the current value of the timer is modified when the END instruction is executed. When the current value of the timer is equal to the set value, its output contacts act when executing the timer coil instruction or the END instruction. If the timer is not used, the work of the timer may not be normal under special circumstances.
If a 1ms timer is used to interrupt programs and subroutines, its contacts act when executing the first coil instruction of the timer after its current value reaches a set value.
Use the T command format (Tn KX), is an example:
OUT T0 K100
It means that when x0 is connected, time is 10 seconds and T0 is connected. Subsequent use of T0 to punish the required output points can achieve the purpose of controlling the time delay.
T is a timer symbol, 0 is a number, K is a constant, is decimal, that is, set to K10 is a second.
Mitsubishi plc ALT alternate command, the first trigger MO ON state, once again triggering becomes OFF state back to ON again trigger state,Cycle.
Select “soft component” option in the GX DEVELOPER software, then set the latch range.
