Người sử dụng có thể lập trình để thực hiện một loạt trình tự các sự kiện. Các sự kiện này được kích hoạt bởi tác nhân kích thích (ngõ vào) tác động vào PLC hoặc qua các hoạt động có trễ như thời gian định thì hay các sự kiện được đếm. PLC dùng để thay thế các mạch relay (rơ le) trong thực tế. PLC hoạt động theo phương thức quét các trạng thái trên đầu ra và đầu vào. Khi có sự thay đổi ở đầu vào thì đầu ra sẽ thay đổi theo. Ngôn ngữ lập trình của PLC có thể là Ladder hay State Logic. Hiện nay có nhiều hãng sản xuất ra PLC như INVT, AllenBradley,Omron, Honeywell

16-bit 32-bit EH3 EH3 EH3 ES EX SS SA SX SC EH SV ES EX SS SA SX SC EH SV ES EX SS SA SX SC EH SV SV2 SV2 SV2 Operands: S: The destination pointer of conditional jump Explanations: Operand S can designate P P can be modified by index register E, F In ES/EX/SS series models: Operand S can designate P0 ~ P63 In SA/SX/SC/EH/EH2/SV series models: Operand S can designate P0 ~ P255 When the user does not wish a particular part of PLC program in order to shorten the scan time and execute dual outputs, CJ instruction or CJP instruction can be adopted When the program designated by pointer P is prior to CJ instruction, WDT timeout will occur and PLC will stop running Please use it carefully CJ instruction can designate the same pointer P repeatedly However, CJ and CALL cannot designate the same pointer P; otherwise an error will occur Actions of all devices while conditional jumping is being executed a) Y, M and S remain their previous status before the conditional jump takes place b) Timer 10ms and 100ms that is executing stops c) Timer T192 ~ T199 that execute the subroutine program will continue and the output contact executes normally d) The high-speed counter that is executing the counting continues counting and the output contact executes normally e) The ordinary counters stop executing f) If the “reset instruction” of the timer is executed before the conditional jump, the device will still be in the reset status while conditional jumping is being executed g) Ordinary application instructions are not executed h) The application instructions that are being executed, i.e API 53 DHSCS, API 54 DHSCR, API 55 DHSZ, API 56 SPD, API 57 PLSY, API 58 PWM, API 59 PLSR, API 157 PLSV, API 158 DRVI, API 159 DRVA, continue being executed Program Example 1: When X0 = On, the program automatically jumps from address to N (the designated label P1) and keeps its execution The addresses between and N will not be executed When X0 = Off, as an ordinary program, the program keeps on executing from address CJ instruction will not be executed at this time DVP-PLC Application Manual 6-1 Application Instructions API 00-49 X0 ( CJ instruction ) CJ P*** P1 X1 Y1 X2 Y2 P1 N Program Example 2: CJ instruction can be used in the following conditions between MC and MCR instructions a) Without MC ~ MCR b) From without MC to within MC Valid in the loop P1 as shown in the figure below c) In the same level N, inside of MC~MCR d) From within MC to without MCR e) Jumping from this MC ~ MCR to another MC ~ MCR1 Actions in ES/EX/SS series models V4.7 (and below): When CJ instruction is used between MC and MCR, it can only be applied without MC ~ MCR or in the same N layer of MC ~ MCR Jumping from this MC ~ MCR to another MC ~ MCR will result in errors, i.e a) and c) as stated above can ensure correct actions; others will cause errors When MC instruction is executed, PLC will push the status of the switch contact into the self-defined stack in PLC The stack will be controlled by the PLC, and the user cannot change it When MCR instruction is executed, PLC will obtain the previous status of the switch contact from the top layer of the stack Under the conditions as stated in b), d) and e), the times of pushing-in and obtaining stack may be different In this case, the maximum stack available to be pushed in is and the obtaining of stacks cannot resume once the stack becomes empty Thus, when using CALL or CJ instructions, the user has to be aware of the pushing-in and obtaining of stacks X0 MC N0 CJ P0 CJ P1 MC N1 X2 X3 X1 M1000 Y1 P1 MCR N1 M1000 P0 Y0 MCR
