Word Bit Description
DYC02 Action Execution Commands
Bits DYC01-B08 - DYC01-B15 and all 16 bits in DYC02 are the 24 action execution commands to control the module. Be-
cause the module cannot respond to more than one action execution command at a time, it ceases all action execution and
sets its outputs to zero when it decodes a valid Dynamic Command Block with more than one of these SET. The module
senses this invalid request and latches alarm status bit SYS14-B00, and unlatches SYS14-B00 when it decodes a valid Dy-
namic Command Block having one or none of the action execution bits SET.

Ram (Screw) Profiles Execution Commands
Bits DYC02-B04 - DYC02-B09 are the six action execution commands available to initiate all profiled ram (screw) movements
(including both decompression movements). You may logically link all six in a single integrated machine movement if all three
Logical Bridge Bits are RESET. These three bits are:
HPC03-B08 - Link Inj/Pack/Hold and Pre-decompress (Inj/Pack/Hold always linked)
HPC03-B09 - Link Pre-decompress and Plastication
PPC03-B08 - Link Plastication and Post-decompress
If all three of these bits are RESET, transfer only DYC02-B04 to the module to force the entire Ram (Screw) portion of an
automatic machine cycle.
B04 = 0 Normal
= 1 Execute Injection Profile
A false-to-true transition of this bit forces the module to do one of the following, attempted in the order listed.
if: then the module:
any of SYS07-B00 through B05 are SET ignores any profile commands
SYS15-B08 is RESET latches SYS13-B05
either of the following are true:
– ram (screw) position exceeds non-zero IPC61
– IPC61 is zero terminates any action in progress and
starts the Injection Profile
both of the following are true:
– ram (screw) position equals or is less than non-zero IPC61
– HPC11 is not zero terminates any action in progress and
starts the Pack Profile
both of the following are true:
– ram (screw) position equals or is less than non-zero IPC61
– HPC11 is zero terminates any action in progress and
starts the Hold Profile
B05 if: then the module:
= 0 Normal
= 1 Execute Pack Profile
A false-to-true transition of this bit forces the module to do one of the following, attempted in the order listed.
if: then the module:
any of SYS07-B00 through B05 are SET ignores any profile commands
SYS15-B11 is RESET latches SYS13-B06
HPC11 is not zero terminates any action in progress and
starts the Pack Profile
HPC11 is zero terminates any action in progress and
starts the Hold Profile
B06 = 0 Normal
= 1 Execute Hold Profile
A false-to-true transition of this bit forces the module to do one of the following, attempted in the order listed.
if: then the module:
any of SYS07-B00 through B05 are SET ignores any profile commands
SYS15-B11 is RESET latches SYS13-B07
this bit (B06) is SET terminates any action in progress and
starts the Hold Profile
