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. Users have to use WPLSoft version 2.31(or above)/ISPSoft version 2.01 (or above).Program example:Ladder diagram:X0Y5RSTInstruction: Operation:LD X0 Load NO contact X0RST Y5 Reset contact Y5Ladder diagram:X0Y5E0RSTInstruction: Operation:LD X0 Load NO contact X0RST Y5E0 Reset contact Y5(Suppose E0=K0)Mnemonic Operands Function Program steps ControllersES2/EX2 SS2 SA2SE SX2MC/MCR N0~N7 Master controlStart/Reset 3Explanations:MC is the master-control start instruction. When MC instruction executes, the program executionturns to the designated nest level and executes the instructions between MC and MCR. However,MCR is the master-control reset instruction placed at the end of the designated nest level and nodrive contact is required before MCR. When MC/MCR is not active, devices and instructionsbetween MC/MCR will operate as the following table.Instruction type ExplanationGeneral purpose timer Present value = 0, Coil is OFF, No action on associated contactSubroutine timer Present value = 0, Coil is OFF, No action on associated contactAccumulative timer Coil is OFF, present value and contact status remainsCounter Coil is OFF, present value and contact status remainsCoils driven by OUT instruction All OFFDevices driven by SET/RSTinstructions Stay intactApplication instructionsAll disabled.The FOR-NEXT nested loop will still execute back and forth for Ntimes. Instructions between FOR-NEXT will act as otherinstructions between MC and MCR.
