Command Blocks
Command blocks provide the parameters that control machine operation.
Command blocks are transferred from the PLC processor to the QDC
module by means of block transfer write (BTW) instructions in software
ladder logic. Command block abbreviations are:
Acronym: Description:
MCC Module Configuration Block
JGC Jog Configuration Block
FCC First Clamp Close Configuration Block
SCC Second Clamp Close Configuration Block
TCC Third Clamp Close Configuration Block
LPC Low Press Clamp Close Configuration Block
CPC Clamp Close Profile Block
FOC First Clamp Open Configuration Block
SOC Second Clamp Open Configuration Block
TOC Third Clamp Open Configuration Block
OSC Clamp Open Slow Configuration Block
OPC Clamp Open Profile Block
EAC Ejector Advance Configuration Block
ERC Ejector Retract Configuration Block
EPC Ejector Profile Block
DYC Dynamic Command Block
CLC Clamp & Eject ERC Values Block
Status Blocks
Status blocks report current status of molding-machine operation. Status
blocks are returned from the QDC module to the PLC processor by means
of block transfer read (BTR) instructions in software ladder logic. Status
block abbreviations are:
Acronym: Description:
SYS System Status Block
CPS Clamp Close Profile Status Block
OPS Clamp Open Profile Status Block
EPS Ejector Profile Status Block
CLS Clamp & Eject ERC Values Status Block
