Xinje XD Series User Manual

 After the execution of an MCS instruction, the bus line (LD, LDI) moves to a point after
the MCS instruction. An MCR instruction resets this to the original bus line.
 MCS, MCR instructions should use in pair.
 The bus line can be nesting. Use MCS, MCR instructions between MCS, MCR
instructions. The nesting level increase with the using of MCS instruction. The max
nesting level is ten. When executing MCR instruction, go back to the last level of bus line.
 When use flow program, bus line management could only be used in the same flow.
When the flow ends, it must go back to the main bus line.
Note: The MCS and MCR instructions can not be written directly in the ladder diagram of
XD/XL series PLC programming software. They can be constructed by horizontal and
vertical lines.
