1.If the piw592 analog input is less than 0 after subtracting 15, jump to f001;

2。Otherwise, execute:

ds_flowers".fl01_flash= (piw592-15)/

The reason why you turn on the flash is not very clear for this nameplate, Siemens LtdChina Siemens (China)****.

The top is the motor model, power, protection level, and product number. The bottom row is V rated voltage, Hz rated frequency, kW rated power, A rated current, efficiency, power factor, and revolutions per minute. Below it doesn't mean much to you, it's the weight of the motor, the date of manufacture, and so on.

PIW analog input.

PQW analogue output.

The first half of the program is to send the PIW data to the MD, and the second half of the program is to transfer the internal MD data to the PQW

These two sections are 3 assignment instructions, and the number in the address after l is written into the address after t.

mw10 to , l mw10 to load mw10 into acc0 t dbw[md20] to load acc0 to pay attention to the data type, it shouldn't make any sense, how does md20 change?

Connect the PLC electric key calendar source first to see if the indicator light is green.

In the case of PLC power, find a communication line and put your program ** to PLCWhen all the settings are correct, the communication port may be broken.

There's a runner on it.

The function block is a function block created for itself, which mainly converts the input analog signal into the actual range and gives the alarm signals at all levels. PIW258 is the actual input address, and the analog range is 0 6 (units, such as kpa), which is the high alarm value and is the low alarm value. The analog quantity after the converted range is stored in the data block, and the address is, the ultra-high limit alarm, the high limit alarm, and the low limit alarm are stored on the bit of the data block.

This is a subroutine! Internally, I did the relevant calculations! The programmer built it himself.

scale h: The upper limit of the range for this variable.

scale l: The lower limit of the range for this variable.

val hh set: the upper limit of the alarm of this variableval h set: the upper limit of the alarm of this variable val l set:

The lower alarm limit setting value of this variable val cur: the value calculated after this variable is set by the range alarm hh: the action after the upper upper limit setting value is exceeded alarm h:

Actions after the upper limit setting value is exceeded.
