2 Functions of Devices in DVP-PLC EH2/SV series MPU: EH3/SV2 series MPU: Note 1: Input point X as a high-speed counter cannot be used as an external interruption signal. For example, if C251 occupies X0, X1, X2 and X3, the external input interruption No. I00 □ (X0), I10 □ (X1), I20 □ (X2), and I30 □ (X3) cannot be used. Note 2: If an interrupt subroutine is executed, the next interrupt subroutine will not be executed until the execution of the interrupt is complete. Note 3: The time it takes for an interrupt subroutine in a PLC to be executed affects the efficiency of the PLC. It is suggested that the size of an interrupt subroutine not be large. Pointer N:
Used with MC and MCR instructions. MC is the master control start instruction. When MC instruction is executer, the instructions between MC and MCR will still be executed normally. See Chapter 3 explanations on MC and MCR instructions for more details. instructions for more details. Pointer P: Used with API 00 CJ, API 01 CALL and API 02 SRET.
See Chapter 6 explanations on CJ, CALL and SRET DVP-PLC Application Manual 2-35 N Master control loop N0 ~ N7, 8 points Control point of master control loop P For CJ, CALL instructions P0 ~ P255, 256 points Position pointer of CJ, CALL I Interruption External interruption I00□(X0), I10□(X1), I20□(X2), I30□(X3), I40 □(X4), I50□(X5), 6 points (□ = 1, rising-edge trigger , □ = 0, falling-edge trigger ) Position pointer of interruption subroutine Timed interruption I6□□, I7□□, 2 points (□□ = 01 ~ 99, time base = 1ms) I8□□, 1 point (□□ = 05 ~ 99, time base = 0.1ms) Pointer High-speed counter interruption I010, I020, I030, I040, I050, I060, 6 points Pulse interruption I110, I120, I130, I140, 4 points Communication interruption I150, I160, I170, 3 points Frequency measurement card triggered interruption I180, 1 point N Master control loop N0 ~ N7, 8 points Control point of master control loop P For CJ, CALL instructions P0 ~ P255, 256 points Position pointer of CJ, CALL I Interruption External interruption I00□(X0), I10□(X1), I20□(X2), I30□(X3), I40□(X4), I50□(X5), I60□(X6), I70□(X7), I90□(X10), I91□(X11), I92□(X12), I93□(X13), I94□(X14), I95□(X15), I96□(X16), I97□(X17), 16 points (□=1, rising-edge trigger , □=0, falling-edge trigger ) Position pointer of interruption subroutine Pointer Timed interruption I6□□, I7□□, 2 points (□□ = 02 ~ 99, time base = 1ms) I8□□, 1 point (□□ = 05 ~ 99, time base = 0.1ms) High-speed counter interruption I010, I020, I030, I040, I050, I060, 6 points Pulse interruption I110, I120, I130, I140, 4 points Communication interruption I150, I160, I170, 3 points
