I know that Omron PLC came in, and the little woman had a question to ask

ld is the first bit of the input channel, ld is the 4th bit of the first channel of the input, out is the 2nd bit of the first channel of the output, and out is the 5th bit of the first channel of the output. ld to out, out to The corresponding address is not the same. ld is the first bit of input channel 2.

It is the output channel 3 bit 2. The first point of the extended input is . The front is the channel, and the back is the bit.

Regarding the addressing of the address, each PLC has regulations, and you can refer to the manual. However, there is still a certain rule to follow, the output of the Siemens 200 comes with the address from the beginning, so it is postponed, and the input is the same, from the beginning. For the input and output points that come with the controller are marked above, you can directly input the programming software.

If you add modules, for example, the CPU is only used in the end, then the extended output is from the beginning. Small PLCs are addressed in this way, and medium and large ones can change the address by themselves, such as Siemens 300, and you can choose the starting address of the module from the software.

ldout

ldout is fine, it is recommended that you first take a good look at the book, understand some plc knowledge, and read his hardware manual.

Omron's timer setting value is in seconds, so 36 seconds should be &360 or

Encoding and constants are two concepts, for example, if one of your BCD address values is 3569, you can understand it as 3569But if you use this address for hexadecimal arithmetic, then this address will be treated as 3569 and its size will be 13673 in decimal, which is not the original meaning at all.

If you read a value in binary format, and then read it in hexadecimal system and bcd, whether the value read is different, so when using instructions or declarations, you must make the type clear.

When using it, use the format conversion command to convert the BCD encoding with the value of 3569 to hexadecimal, then this address will store df1, which is equivalent to &3569. Indicate the appropriate format so that the program compiler can recognize it correctly.

If you want to learn coding, it is recommended that you read the principle of microcomputer, the principle of microcomputer and interface, if the book is in the first 3 chapters, it is the basic knowledge of programming.

Don't ask so complicated, landlord, you can directly click on the command in the cx-programmer, and then press the instructions in the F1 help. I remember that the timer was special, and then it was followed by the decimal system.

The so-called immediate number can be understood as the decimal system.

For a 100ms timer, the SV value of 360 represents 36 seconds.

Just run it with physical programming.

Hello, now the CP1H series PLC can realize the writing of pulse control instructions (such as PLS2) in the function block. In the previous version (previous version), if the variable name of the function block was in Chinese, the CX software would automatically close, and the variable name in the old version did not support Chinese. Now the latest version can support the function block variable name as a Chinese name.

Operate in standalone mode:

1) In standalone mode, only the number of output pulses specified by puls(065) will be output.

2) Before executing SPED(064), the number of output pulses must be specified by executing puls(065). (If the number of output pulses is not prespecified, the pulses will not be output.)

3) When the calculated number of pulses is negative, the absolute value of the number of pulses will be used. (For example, if the number of strokes is -500, the value of 500 will be used), as shown in Figure 1 for example.

Operation in continuous mode:

1) In continuous mode, the pulse is output at a defined value and does not stop until the INI (061) instruction with C = 003 is executed, or the SPED (064) instruction with F = 0000 is executed again or the PLC is switched to programming mode, as shown in Figure 2 for example.

Omron is at most a mid-range PLC, and even if it is a redundant structure like CS1D, it is not high-end.

Siemens is a mid-to-high-end product.

For the switching quantity, it is almost the same, but in terms of the number of modules, Omron is much worse.

There is no comparison between the products of these two manufacturers.

Programming concepts vary greatly, generally speaking, the Japanese concept of Omron and other systems is that the hardware configuration determines the IO address in the software, while the concept of Siemens, AB, etc. is to try to be independent of the hardware, and the IO address is determined by the configuration.

The difference is quite big, and the usage address of the program ** and various relays is not the same.

Data processing speed: Siemens, Mitsubishi, Omron.

Motion Control Speed: Mitsubishi Siemens Omron.

**Value for money: Omron, Mitsubishi, Siemens.

Summary. Dear will be happy to answer for you. Omron PLC how to see which year of production, look at the serial number of PLC, PLC serial number a total of 8 digits (there are three types of identification starts, one is:

One is d: the beginning, and the other is the date code: the beginning).

The first digit indicates the number of weeks of production, e.g. 12 indicates the 12th week of production, and the first digit indicates the year of production, e.g. 06 indicates 2006.

Dear will be happy to answer for you. Omron PLC how to see which year of production, look at the serial number of PLC, PLC serial number a total of 8 digits (there are three types of identification starts, one is: the beginning, one is D:

and one is date code:. The first digit indicates the number of weeks of production, e.g. 12 indicates the 12th week of production, and the first digit indicates the year of production, e.g. 06 indicates 2006.

Dear, you can also check the product manual or contact the manufacturer for more information about the production date. Pro, the production batch number is, the production date is January 9, 09, because I just found Omron's product batch number, such as: 13509S,
