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 Open
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.
