--Materials--

(1) One computer with ZDevelop3.01 or above installed.

(2) One controller.

(3) One 24V DC power supply

(4) Several bus drive + motor (or stepper drive + motor).

(5) A number of controller wiring terminals.

(6) Several network cables.

(7) A number of connecting wires.

(8)  Several expansion modules of different types.

--Wiring Reference--

(1) U Disk Main Applications

There are two main applications for our Zmotion motion controller U disk.

And generally, usage methods of U disk interfaces on different controller models are the same.

That is, insert U disk into UDISK terminal of controller, then power on the controller. When U disk indication led lights, which means it is successful.

Then, let me show what are the main applications for the U disk?

--upgrade program--

Through this U disk interface on controller, users can update system program conveniently.

Before upgrading, download ZAR program package into U disk. Then, when succeeds in loading U disk file through the command, ZAR program will automatically run.

--interact data between U disk and register--

U disk can read and write variables and arrays.

Flash can copy the data, then in multiple controllers, data saved in FLASH can be transferred by U disk.

The same, data in VR register, in TABLE register and data in U disk all can be interacted.

For files that can be read and written are SD(filenum).BIN or SD(filenum).CSV, but different file types are with different commands.

Next, let's see details about commands.

(2) U Disk Read & Write Commands

U_STATE: judge the U disk state, when detects there is the U disk inserted, return to "TRUE", otherwise return to "FALSE".

--U disk reads and write variables, arrays--

U_READ: read data from U disk into variables or arrays.

U_READ2: read data from U disk into variables or arrays, and reading initial position can be selected.

U_WRITE: save variables or arrays, one single element or some elements in array are saved into external storage.

--U disk interacts with data in registers--

Note: data reading and writing through U disk is same format with TABLE and VR.

STICK_READ: read data from U disk into table.

STICK_WRITE: copy data from TABLE into U disk.

STICK_READVR: read data from U disk into VR.

--U disk reading and writing examples--

Firstly confirm U disk has been inserted, then use U_STATE command to judge U disk status, next operate reading and writing.

Instructions: U_READ, U_WRITE.

Examples:

DIM a,ARRAY1(2)   'define variables, arrays

a=123

ARRAY1(0)=10

ARRAY1(1)=20  

IF  U_STATE = TRUE THEN   'judge whether U disk is inserted

      U_WRITE 0,a,ARRAY1     'write variables and arrays into U disk

      a=456

      ARRAY1(0)=11

   U_READ  0,a,ARRAY1     'read U disk file SD0 data

      IF a <> 123 THEN       'judge whether U disk reads and write successfully

             PRINT "U Disk Fails to Read"

      ELSE

             PRINT "U Disk Succeeds to Read"

      ENDIF      

ELSE

      PRINT "U Disk Uninserted"

ENDIF

Attention: the order of storing and reading data in the U disk must be consistent.

And when there is no controller, the simulator can be used to create a new udisk file in the root directory of the programming software to simulate a U disk. Put the files to be used in the command operation of the U disk into this folder.
