(for pulse relay)2Trailingedge out OT↓Outputs the operated result to the specifiedoutput only for one scan when trailing edge ofthe trigger is detected. (for pulse relay)2Alterna-tive outALT Inverts the output condition (on/off) each timethe leading edge of the trigger is detected. 3ANDstackANS Connects the multiple instruction blocksserially. 1OR stack ORS Connects the multiple instruction blocks inparallel. 1: Available, : Not available, : Not available partially*1) The type of the devices that can be specified depends on the models.*2) This instruction is available for FP-X Ver. 2.0 or later, and FPΣ Ver. 3.10 or later.*3) In the FP2/FP2SH/10SH, when using X1280, Y1280, R1120 (special internal relay included), L1280, T256, C256 oranything beyond for the ST, ST/, OT, AN, AN/, OR and OR/ instructions, the number of steps is shown in parentheses.Also, in the FP2/FP2SH/FP10SH, when a relay number has an index modifier, the number of steps is shown inparentheses. For the FPΣ and FP-X, the number of steps varies according to the relay number to be used.
