Anonymous users2024-02-06The function of the zrst instruction in the triangular PLC is to reset the interval, and the format is zrst D1· D2· , which is to reset all the components in the specified interval of the operands D1 and D2, and the address code of D2 should be D1.
The interval reset command ZRST with the command code FNC40 is used to reset similar components within the specified part number range of D1· and D2·
The target operand can be t, c, d or y, m, s, d1· , d2· The specified components should be of the same type, and the number of components of d1· should be less than d2· . If the number of elements of d1· is greater than that of d2· , then only the elements specified by d1· will be reset.

1. Introduction: interval reset instruction zrst, instruction ** is FNC40, and its function is to set [d1·], d2·] Homogeneous components within the specified part number range are re-placed, and the target operands can be T, C, D, or Y, M, S. [d1·]、d2·] The specified component should be of the same kind.
2、zrst：
ZRST is an interval reset instruction. The corresponding directive should be the RST directive, which belongs to the same meaning. All are for resetting.
The difference is that RST resets an address. ZRST resets a "contiguous" address.
3. For example: zrst y000 y007, that is, to reset all eight address bar states including y000, y001, y002 y007, this is an interval continuous reset instruction.
The use of RST is very simple, RST Y 001 is to reset a port.

It is a command to reset all soft components within a certain range.
That is, all the points within the selection range are restored to their original state.

Anonymous users2024-02-02The interval comparison command ZCP compares one source data with two source data, and the comparison result will affect the data status of the target memory.
Replace an operand [s.]] with two operands [s1.] and [s2.]
Comparison of the formed intervals, and [s1.] must not be greater than [s2.]], and the results were sent to [d.].
Middle. When x0 is turned on, the values of m3, m4 and m5 are assigned according to the comparison results between c30 and k100 and k120.

Anonymous users2024-02-01RST is an abbreviation for reset, which is a reset instruction that resets the state of a soft component to the off state, and the reset timer and counter and data register to the state of 0.
PLC's common jujube is missing the basic instructions:
1. LD: Take the command (normally open contact).
2. LDI: Counter Instruction (Normally Closed Contact).
3. AND: Serial command (normally open contact).
4. ANI: Serial Reverse Instruction (Normally Closed Contact).
5. OR: and command (normally open contact).

Anonymous users2024-01-28Mitsubishi PLC's RS command is a serial data transmission instruction, and its parameter M represents the number of data sent, N represents the number of received data, S sends the data storage word element head address, and D receives the data store word element head address.
When the RS instruction is valid, it informs the PLC that M data at the address with the head S are waiting to be sent and is ready to receive up to N data, stored in a register with the address with the head of D.
RS commands are used to send and receive serial data to expansion function boards such as RS232 and RS485 and special adapters. The number of data received and sent can be set using the d register or directly with the k and h constants.
In systems that do not transmit data, set the number of units to be sent to k0; In systems that do not receive data, set the number of received data to k0.

Send data of length D0 starting from D200, set M8122 to start sending, and reset M8122 after sending is completed.
The received data is placed at the length of D1 starting with D500, and M8123 is the receive completion flag.

These two are mainstream PLCs, one made in Japan, one made in Germany, I have used both, both are very representative, it is recommended to learn both, you can learn Mitsubishi's first, because most of the programming methods of other brands of PLC are imitation of Mitsubishi, especially domestic brands, just like the Delta I use now, and Xinjie, which is almost exactly the same as Mitsubishi. Mitsubishi is what a traditional ladder looks like. And Siemens is also unique, although he also said that it is a ladder diagram, but his is a modular ladder diagram, which looks more intuitive than Mitsubishi's, and the step7 software is also very easy to use. >>>More
The frequency conversion is more energy-saving, at least 30% less than ordinary air conditioners, but it must be used for more than 7 hours a day to reflect its energy-saving effect, otherwise it is much different from ordinary air conditioners.
I am a horticulture major, and the broad concept of horticulture refers to the cultivation and breeding techniques of fruit trees, vegetables, flowers and ornamental trees. Graduates of the horticulture major have special advantages in various agricultural production and theory at the same time. In ancient times, the cultivation of fruit trees, vegetables and flowers was often confined to a small area of gardens, which was different from field agricultural production, so it was called horticulture. >>>More
