Mnemonic Operands Function Program steps
MPS
X, Y, M, S, T, C
Store the current result of the internal ELC
operations

ELC ELCB ELCM
PB PC/PA/PH PV PB PH/PA
Description:
MPS stores the connection point of the ladder circuit so that further coil branches can recall the
value later.
Mnemonic Operands Function Program steps
MRD X, Y, M, S, T, C
Reads the current result of the internal ELC
operations

ELC ELCB ELCM
PB PC/PA/PH PV PB PH/PA
Description:
MRD recalls or reads the previously stored connection point data and forces the next contact to
connect to it.
Mnemonic Operands Function Program steps
MPP X, Y, M, S, T, C
Pops (recalls and removes) the currently
stored result

ELC ELCB ELCM
PB PC/PA/PH PV PB PH/PA
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.
