Is a research and development and production of PLC and programming cable, wireless communication, the Internet of things, servo, touch screen and other automation products of high-tech enterprises.We adhering to the "strives for the survival by the quality, seek development by innovation" concept of development, always give top priority to quality and innovation.
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.
Siemens 6es7972-0cb20-0xa0 driver installation instructions, if you are not using a special cable, you only need to fully install the corresponding software, higher version. Some low version software does not have integrated chip drivers.
From the reverse side of the product, it is the 8+9 double raw interface which is close to the USB interface. The reference of interface definition is Picture
As the picture shows, the MPG port totally have 17 wiring terminals, and the
reference of eachwiring terminal definition is table
The reference of corresponding relation,between system and MPG wiring is table
Note: It you want to use the single-terminal MPG (namely there is no A-B-MPG),
please look at the wiring table, the table for reference. As for the unlisted one, please take the differential MPG wiring mode
