PLC
Expert Response Compensation (ERC) Percentage
Word Description
PLC05 Minimum RPM Control ERC Percentage [31]
PLC06 Minimum Pressure Control ERC Percentage [31]
Although error coding allows range of 00000 to 09999, the module limits it to a minimum of 01000.
PLC07 RFU
Watchdog Timer
Word Description
PLC08 Profile Watchdog Timer Preset [21] When the module starts Plastication Profile, it:
S starts an internal Profile Watchdog timer
S stops this timer and reset its accumulated value to zero (after reporting total execution time in PPS57) when it completes the profile
S sets master status bit SYS04-B08 when the accumulated value of this timer equals or exceeds this entry
A zero entry inhibits SYS04-B08.
Unselected Valve Set-output Values
When the module starts the Plastication Profile, it:
•
ignores the unselected value of the selected output
•
uses ramp rates PLC17-20 and PLC25-28 to ramp unselected outputs
•
sets its unselected outputs to the values listed below
Word Description
PLC09 Output #1 Set-output Value during Profile [19]
PLC10 Output #2 Set-output Value during Profile [19]
PLC11 Output #3 Set-output Value during Profile [19]
PLC12 Output #4 Set-output Value during Profile [19]
PLC13-16 Reserved for Future Use
Output Ramp Rates
The module uses the following ramp rates when moving its outputs
from setpoint to setpoint during the Plastication Profile. The module
interprets a ramp rate of zero as a step function ramp (ramp disable).
Word Description
PLC17 Output #1 Acceleration Ramp Rate during Profile [20]
PLC18 Output #2 Acceleration Ramp Rate during Profile [20]
PLC19 Output #3 Acceleration Ramp Rate during Profile [20]
PLC20 Output #4 Acceleration Ramp Rate during Profile [20]
PLC21-24 RFU
PLC25 Output #1 Deceleration Ramp Rate during Profile [20]
PLC26 Output #2 Deceleration Ramp Rate during Profile [20]
PLC27 Output #3 Deceleration Ramp Rate during Profile [20]
PLC28 Output #4 Deceleration Ramp Rate during Profile [20]
