When the SET instruction is driven, its designated device will be ON and latched whether theSET instruction is still driven. In this case, RST instruction can be applied to turn off thedevice.2. DVP-ES2/EX2 series PLCs whose version is 3.20/DVP-SS2 series PLCs whose version is3.00/DVP-SA2 series PLCs whose version is 2.60/DVP-SE series PLCs whose version is1.20/DVP-SX2 series PLCs whose version is 2.40 (and above) support the operands Y, M,and S. These operands can be qualified by E or F.
