6.18 Subroutine 6.18.1 Using subroutine Subroutine is used for program partitioning.When the main program calls subroutine and performs the subroutine,subroutine executes all instructions to the end.Then, the system returns to the main program. Subroutine is used for program partitioning.It helps to read and manage programs. It also helps to debug and maintain programs.You can use PLC more effectively by using subroutine.Because all of the subroutine blocks are not scanned when they are not called.
Page 214: Using Parameters To Call Subroutine
6.18.2 Using parameters to call subroutine Subroutine may contain the transfer parameters.The parameter is defined in the local variable table of the subroutine.Parameters must have a symbol name (up to 23 characters), a variable type, and a data type.Each subroutine can be set up to 16 IN/OUT parameters.

Read / Read / Read / Read / write write write write 7.2 Direct and indirect addressing When you write the program, you can use the three ways to address instruction: 1.Direct addressing 2.Symbol addressing 3.indirect addressing Direct addressing PLC can directly specify the memory area, size, and location; In order to read/write a bit in the memory area, you need to specify the address.
Page 221 Symbolic addressing Symbol addressing consists of letters, numbers and characters. You can set the symbol of address by the following steps: You can enter “start” as the address of I0.0 Indirect addressing Indirect addressing uses pointer to access the data of memory. Pointer is a double word.It contains the address of another memory location.
Page 222 Pointer consists of memory location and symbol "&”. To specify the operand be a pointer , you should input an asterisk (*) in front of the operand. Example:The values stored in the VB200 and VB201 are moved to AC0. As shown in the figure below, you can change the pointer value.Because the pointer is a 32 bit value, you should use the double word instruction to modify the pointer value.
Page 223: Bit, Byte, Word And Double Word Access
interval is 4. If the value of the pointer is greater than the maximum value of the V memory, program will generate errors.

Page 243 Supplementary explanation:MASK input is a byte.Take VB0 as an example: When 0 bit is equal to 1, LCD will display 0 group. When 1 bit is equal to 1, LCD will display 1 group. When 2 bit is equal to 1, LCD will display 2 group. When 7 bit is equal to 1, LCD will display 7 group.
Page 244 For example： You have to edit display pages in LCD software. Display page 1: Display page 2: Display page 3: Display page 4:...
Page 245 Grouping of display pages in display page property: Display page 1：Display page 1 is divided into 0 group and 1 group. Display page 2：Display page 2 is divided into 0 group and 1 group. Display page 3：Display page 3 is divided into 0 group. Display page 4：Display page 4 is divided into 0 group.
Page 246 PLC program: Analysis: In network 0,the program binds LCD keys and PLC variables. PLC has ten function keys.Each function key corresponds to a PLC variable. F1 corresponds to SM191.0 F2 corresponds to SM191.1 F3 corresponds to SM191.2...
Page 247 F4 corresponds to SM191.3 ESC corresponds to SM190.0 corresponds to SM190.1 corresponds to SM190.2 DOWN corresponds to SM190.3 LEFT corresponds to SM190.4 RIGHT corresponds to SM190.5 NETWORK 0: MODIFY is ESC function key，corresponds to SM190.0 The functions of function keys: You can customize F1~F4.
Page 248 VB200 is 1.0 bit is equal to 1,so LCD displays 0 group.The value of VB201 is 0, which means the first display page.The first display page is display page 1. You can use the program to specify the display group and the display page . For example: The LCD will display group 1 and display page2.
Page 249 For example: When you modify the first variable of display page 1: The instruction will display as follows: Vb205 = 0 Variable 0,the first variable. Vb206 = 1 It means that you can use LCD function keys to edit variables. Vb207 = 1 It means you can modify single digit.Vb207 = 2,you can modify single digit and tens digit.
Page 250 For example: Modify the value of variable to 161. For example: Modify text list VB205 Variable 1, the second variable. VB206 It means that you can use LCD function keys to edit variables. VB207 Edit depth is 1. VB208 LOOP VB209 No flicker VD210...
Page 251: Can, Serial Port Initialization Instructions
10.7.2 CAN, serial port initialization instructions UART_Init CAN_Init CAN_Init instruction is used to initialize the CAN port. l EN：If the input value is 1,the instruction will initialize the CAN port. l PORT：port number，0~1。 l BR：CAN port baud rate UART_Init instruction is used to initialize the serial port. l EN：If the input value is equal to 1,the instruction will initialize the serial port.
