Parameter setting success.
Below by taking the modification of individual character type parameter as an example, the method implementation process to the present invention does a detailed introduction, such as Fig. 3
It is shown：The functional block is used to change frequency converter individual character type parameter after calling in PLC.Due to more than P2000 and below P2000
Converter parameter mark, when being sent to communication data block address, communication packet rule is different, so the functional block is first
First basis inserts PKE (Parameter Kanal Eentry parameter channel entrances.Fill in converter parameter mark) frequency converter
Parameter identification automatic decision is more than 2000 or less than 2000, and the functional block can be advised according to corresponding message after the completion of judgement
Then, the binary number of PKE binary number and the task recognition Tag ID of modification individual character parameter is subjected to " logical AND " computing, fortune
Result is calculated to be sent in communication data block address PKE_OUT (converter parameter identifies PKE output valve).Next, the function
IND binary number is carried out " logical AND " by block also according to the message rule below converter parameter more than 2000 and 2000
It is sent to after computing in IND_OUT (converter parameter subscript IND output valve).Equally, the functional block can PWE value according to
The requirement of individual character categorical data is sent in PWE_OUT (converter parameter actual value PWE output valve).Converter parameter has been changed
Cheng Hou, the functional block be able to will be become by PKE_BAK, IND_BAK, PWE_BAK (_ BAK represents reading value) communication data block address
Frequency device parameter is read in functional block, is contrasted with the converter parameter (PWE, IND, PKE) modified before.Contrast knot
After fruit is correct, the functional block judges that converter parameter is successfully modified, is state of activation at OK.
Wherein, PKE is the converter parameter mark for needing to change.If desired for converter parameter P2010 to be changed1, then
2010 are just inserted in PKE.
IND is the converter parameter subscript for needing to change.Converter parameter if desired for modification is P20101, then just exist
1 is inserted at IND.
PWE is the converter parameter actual value for needing to change.If desired for by converter parameter P20101It is revised as 6, then
6 are just inserted in PWE.
PKE_OUT, IND_OUT, PWE_OUT are the communication data block address that PLC is used for changing converter parameter.Due to this
The invention of timer is built upon PLC and set up with frequency converter on the basis of DP periodic communications, so PKE_OUT, IND_
OUT, PWE_OUT communication data block address are identical with original DP periodic communications address.
PKE_BAK, IND_BAK, PWE_BAK are the communication data block address that PLC is used for reading converter parameter.Due to this
The invention of timer is built upon PLC and set up with frequency converter on the basis of DP periodic communications, so PKE_BAK, IND_
BAK, PWE_BAK communication data block address are identical with original DP periodic communications address.
It is emphasized that above method step is not necessarily performed according to number order, why it is intended merely to numbering
The convenience of statement, as long as the purpose of the present invention can be realized, changing in any step should all be protected in the claim of the present invention
In the range of.
As shown in Fig. 2 the present embodiment sets device using the method for above-described embodiment there is provided a kind of converter parameter, build

Logical operation process module, it is for the message rule determined using the message rule determining module, the input is single
The parameter type that target binary number is determined with the parameter type acquisition module under the parameter identification and the parameter of member input
The binary number of task recognition Tag ID carry out " logical AND " computing, and operation result is sent to the PROFIBUS DP
In the communication data block address of communication write-in data function module；
Parameter modification completes module, and the communication data block of data function module is write for being communicated by the PROFIBUS DP
Address is written in the frequency converter, and the parameter in the frequency converter is modified.
8. device as claimed in claim 1, it is characterised in that also include：Judging unit, for the ginseng in the frequency converter
Number modified values are read out, and judge whether the parameter modified values in the frequency converter are consistent with the parameter actual value, if one
Cause, then return to the successfully modified mark of parameter of the frequency converter.
9. a kind of computer-readable recording medium, is stored thereon with computer program, it is characterised in that the program is held by processor
Following steps are realized during row：
Set up by main website of PLC, frequency converter is the PROFIBUS DP communications between the PLC and frequency converter of slave station；
The periodic data communication communicated using the PROFIBUS DP, passes through parameter identification, parameter subscript, parameter actual value
Input to frequency converter carry out arbitrary parameter setting.
10. a kind of converter parameter sets equipment, including memory, processor and store on a memory and can be on a processor
The computer program of operation, it is characterised in that realize following steps during the computing device described program：
Set up by main website of PLC, frequency converter is the PROFIBUS DP communications between the PLC and frequency converter of slave station；
The periodic data communication communicated using the PROFIBUS DP, passes through parameter identification, parameter subscript, parameter actual value
Input to frequency converter carry out arbitrary parameter setting.
