6 Application Instructions API 00-49 X0 Y1 Enable interruption DI Disable interruption EI Enable interruption FEND I 101 Y0 IRET Interruption subroutine A I 201 Y0 Interruption subroutine B IRET Remarks: 1. No. of interruption pointer I in ES/EX/SS: a) External interruptions: (I001, X0), (I101, X1), (I201, X2), (I301, X3) 4 points 2 . b) Time interruptions: I6 □□ , 1 point ( □□ = 10 ~ 99, time base = 1ms) (support V5.7 and above) c) Communication interruption for receiving specific words (I150) (support V5.7 and above) 2. No. of interruption pointer I in SA/SX/SC: a) External interruptions: (I001, X0), (I101, X1), (I201, X2), (I301, X3), (I401, X4), (I501, X5) 6 points.
b) Time interruptions: I6 □□ , I7 □□ 2 points. ( □□ = 1 ~ 99ms, time base = 1ms) c) High-speed counter interruptions: I010, I020, I030, I040 4 points. (used with API 53 DHSCS instruction to generate interruption signals) d) Communication interruption for receiving specific words .(I150) e) The order for execution of interruption pointer I: high-speed counter interruption, external interruption, time interruption and communication interruption for receiving specific words. f) Among the following 6 interruption No., (I001, I010), (I101, I020), (I201, I030), (I301, I040), (I401, I050), (I501, I060), the program allows the user to use only one of the two numbers in a pair.
If the user uses the two numbers in the pair, grammar check errors may occur when the program is written into PLC. 3. No. of interruption pointer I in EH/EH2/SV: a) External interruptions: (I00 □ , X0), (I10 □ , X1), (I20 □ , X2), (I30 □ , X3), (I40 □ , X4), (I50 □ , X5) 6 points. ( □ = 0 designates interruption in falling-edge, □ = 1 designates interruption in rising-edge) b) Time interruptions: I6 □□ , I7 □□ , 2 points. ( □□ = 1~99ms, time base = 1ms) I8 □□ 1 point. ( □□ = 1 ~ 99ms, time base = 0.1ms) c) High-speed counter interruptions: I010, I020, I030, I040, 1050, 1060 6 points.
(used with API 53 DHSCS instruction to generate interruption signals) d) When pulse output interruptions I110, I120 (triggered when pulse output is finished), I130, I140 (triggered when 2 Input points occupied by external interruptions cannot be used for inputs of high-speed counters; otherwise grammar check errors may occur when the program is written in PLC.
