Operand Description Data Type
n 0 ~ 7 for XGB WORD(0~15)
1) MCS, MCSCLR
(1) If MCS’s input condition is On, functions up to MCSCLR with identical MCS number will be executed. If input
condition is Off, nothing will be executed.
(2) MCS number 0 is the highest, 7 the lowest, used in priority sequence. Clearing will be opposite.
(3) MCSCLR clearing of high priority data will also clear MCS Block with low priority.
(4) MCS or MCSCLR should be used in priority sequence.
2) Program Example
Where 2 MCS Instructions are used and “0” with high priority is used for MCSCLR Instruction.

Remark
1) If MCS’s On/Off Instruction is Off, MCS ~ MCSCLR’s operation result will as follows; Be careful when
using MCS (MCSCLR) Instruction.
· Timer Instruction: Not Processed. Identical Process to contact Off
· Counter Instruction: Not Processed (Present value kept)
· OUT Instruction: Not Processed
· SET, RST Instruction: Result Kept
