Storing/reading/clearing the operation result
MPS, MRD, MPP
• MPS: This instruction stores the preceding operation result (ON/OFF) to memory.
• MRD, MPP: These instructions read the operation result stored by the MPS instruction, and executes operations from the
next step using that operation result.
â– MPS
• This instruction stores the preceding operation result (ON/OFF) to memory.
• This instruction can be used up to 16 times consecutively. When MPP instruction is used in between, the number of uses of
MPS instruction is decremented by 1.
â– MRD
• This instruction reads the operation result stored by the MPS instruction to memory, and executes operations from the next
step using that operation result.
â– MPP
• This instruction reads the operation result stored by the MPS instruction to memory, and executes operations from the next
step using that operation result.
• This instruction clears the operation result stored by the MPS instruction from memory.
