PSC
Word Description
PRC37 Output #5 Set-output Value at End of Movement [19]
PRC38 Output #6 Set-output Value at End of Movement [19]
PRC39 Output #7 Set-output Value at End of Movement [19]
PRC40 Output #8 Set-output Value at End of Movement [19]
PRC41 - 56 Open
Movement Pressure Alarm Setpoint
Word Description
PRC57 Movement High Pressure Alarm Setpoint [01] The module compares real-time ram (screw) pressure against this entry during the
Pre-decompression Movement. The module sets alarm status bit SYS06-B06 when ram (screw) pressure equals or exceeds this
entry during the Pre- decompression Movement. A zero entry inhibits SYS06-B06.
PRC58 - 64 Open
Bit-mapped Control Words
Word Bit Description
PSC01 Block ID = 00010000 (Low byte). High byte reserved for the module. Do not use.
PSC02 - 04 Open
Movement Length
Word Description
PSC05 Incremental Movement Length [17] When the module starts the Post-decompression Movement, it adds this entry to the sum of
cushion size (PPC61) + shot size (PPC62) to establish the End of Post-decompression ram (screw) position. The module uses End
of Post-decompression position as termination point of all Post-decompression Movements.
PSC06 - 07 Open
Watchdog Timer
Word Description
PSC08 Movement Watchdog Timer Preset [21] When the module starts the Post-decompression Movement, it:
S starts an internal Movement Watchdog timer
S stops this timer and resets its accumulated value to zero (after reporting total execution time in PPS58) when it completes the
movement
S sets master status bit SYS04-B09 when the accumulated value of this timer equals or exceeds this entry.
A zero entry inhibits SYS04-B09.
Movement Set-output Values
When the module starts the Post-decompression Movement, it:
•
sets its outputs to the values listed below
•
uses ramp rates PRC17 - PRC32 to ramp outputs
Word Description
PSC09 Output #1 Set-output Value during Movement [19]
PSC10 Output #2 Set-output Value during Movement [19]
PSC11 Output #3 Set-output Value during Movement [19]
PSC12 Output #4 Set-output Value during Movement [19]
