08 Macro Script

This chapter provides information about scripts in PIStudio.

= **Script type** =

Script is applied to realize complex control functions. HMI compile software provide powerful function, simple operation, reliable script system, the features of script are list as follow:

6

7

Similar to BASIC grammatical structure;

8

9

* BASIC work as the first computer language for the general public, it is easy and efficient to use.

10

11

Support all of program logic control structures;

12

13

* Software script supports three logic control structures: order, condition, loops. It could realize complexity procedures.

14

15

Powerful function; Functions of script are divided into two types: system and custom function.

16

17

* System function: the functions that system has been predefined for users.

18

* Custom function: users could define a function and apply to all scripts.

19

20

Support variety of data format;

21

22

* Script supports integer, floating, BCD code, byte, string and etc.

23

24

**Scripts Running Method**

25

26

1. **Background Script:** Run independently during start project, screen updates have no influence and valid of all scripts.

27

1. **Screen Script:** Only run under the designated screen. Screen script start running until screen is closed or switched.

28

29

And both screen and background have four modes for script

|=**Property**|=**Description**

33

|Initialize|The script would be executed once during loading project.

34

|Close|The script would be run once during closing HMI project.

35

|Timing|The script would run under certain conditions after the HMI is started, until the condition ends.

36

|Bit trigger|Script would be repeat executed when meet the condition of bit trigger.

= Script usage =

Script can make project more convenient and flexible. Script is useful in realizing complex HMI function. If the script is used improperly, it may affect the efficiency of entire project. So pay attention to the follow issues:

208

209

* Do not use too much script loops, if the script loops that execute too many times; it might influence the efficiency of HMI.

210

* In the cycle scripts, avoid using external register, due to the relatively slow serial communication, frequent access to external registers may cause the execution of scripts severely reduced, even influence the screen respond efficiently. There is fine to use internal register.

211

* The maximum script length is 512 rows.

212

213

This section describes how to edit scripts and use some of the accompanying tools and features of the script editor.

214

215

== **Script access to d evice** ==

216

217

Software script supports an efficiency way to access the device address by using symbol @.

|=**Writing**|=**Meaning**|=**Examples**

221

|@B_;@b_;|Access designated bit address|(((

222

|@W_;@w_;|(% rowspan="2" %)(((

230

231

)))|(((

233

@W_IW0:access word address IW0

237

|@B_(the number of protocol connection)#(station number):address|(((

238

@B_2#2:I0.0:access the bit address I0.0, with the connection number 2 and station number 2;

239

240

@B_I0.0:access to bit address I0.0;

241

)))

242

243

The script can access with the device though: write and read.

**For example**

If @B_HDX0.0 = 1 then 'read the value from address HDX0.0.

249

250

@B_HDX0.0 = 0 'write 0 to address HDX0.0

Else

@B_HDX0.0 = 1 'write 1 to address HDX0.0

Endif

@W_QW0 = @W_QW0 + 1 'read data from address QW0, add 1 to this value then write to address QW0

== **FILL** ==

**Function**

FILL (A1, A2, A3)

**Description**

Write the same value to designated address constantly.

**Parameters**

**A1:** The beginning address, it can be an address (e.g.@ W_ HDW25);

1927

1928

**A2:** Source data, it needs to be written in continuous value, the value can be an address, variable or constant;

1929

1930

**A3:** The number of operation, writing address number, it can be an address, variable or constant;

1931

1932

When the PLC (external device) address is used in this function, the length range is 1-2048, and only the 2048th address can be operated when the range is exceeded.

1933

1934

When the HMI internal address is used in this function, the length range is 1-4096. If the function is out of range, then the function is invalid.
