6 Application Instructions API 00-49 API 47 Explanations: 1. No operand. 2. This instruction is used for resetting the annunciator. 3. When more than one annuciators are On, the annunciator of smaller number will be reset. 4. This instruction adopts pulse execution instructions (ANRP) Program Example: 1. If X10 and X11 = On at the same time for more than 2 seconds, annuniciator point S910 = On. Even X10 and X11 go Off afterwards, S910 will still keep On. However, T10 will be reset to Off and the present value = 0. 2. When X10 and X11 are On at the same time for less than 2 seconds, the present value of T10 will be reset to 0. 3.
When X3 goes from Off to On, S896 ~ S1023 in SA/SX/SX are able to reset the annunciators in action. S900 ~ S1023 in EH/EH2/ SV/EH3/SV2 are able to reset the annunciators in action. 4. When X3 goes from Off to On again, the annunciator with secondary smaller No. will be reset. X10 X11 X3 Remarks: 1. Flag: a) M1048 (annunciator in action): When M1049 = On, any of the annunciators among S896 ~ S1023 in SA/SX/SC or S900 ~ S1023 in EH/EH2/SV/EH3/SV2 starts output, M1048 will be On. b) M1049 (valid monitoring): When M1049 = On, D1049 will automatically display the annuciator of the 2. Application of annunciators: smallest number in action. I/O point configuration: X0: Forward switch Y0:
