Description:
MPP pops (recalls and removes) the stored connection point. First, it connects the next contact,
then it removes the point from the temporary storage area.
Basic points to remember:
1.
Use these instructions to connect output coils to the left hand side of a contact. Without these
instructions connections can only be made to the right hand side of the last contact.
2.
For every MPS instruction there MUST be a corresponding MPP instruction.
3.
The last contact or coil circuit must connect to an MPP instruction.
4.
At any programming step, the number of active MPS-MPP pairs must be no greater than 8.
