Watlow 8PID Controller - Manual (Page 50)

Example:
Command: X2LQ
Response: X2L0100
Setting any alarm value updates both the run-time (RAM) and stored (ROM) data. On
power-up the alarm values will be read from EEROM storage and will default to their
last entered value.
3.3. SAVING PARAMETERS TO EEROM STORAGE
The user may instruct the ANAFAZE 8 PID to save all current parameters in EEROM
for use as default values on next power-up or microprocessor reset.
XEW EW indicates EEROM Write
Response: XED D indicates EEROM write Done
NOTE: Saving run-time variables will also store the current output levels and these
level states will be set upon power- up or reset. If it is not desired to save these
output states, the host must set or clear output lines prior to issuing the EEROM
Write Command.
The following parameters are saved during the EEROM WRITE operation:
Input Type High Alarm Setpoint
Control Setpoint Low Alarm Setpoint
Proportional Gain Value (Kp) High Alarm Deadband
Integral Multiplier (Tm) Low Alarm Deadband
Integration Time (reset) (Ti) Expander Mode (Alarm or Control)
Derivative Value (rate) (Td) Alarm Deadband Percentage
Output Filter Value (Df) I/O Line Data Direction
Analog Output ON/OFF Indicator Expander Card Input States
Time Proportioning Cycle Time (Tr) Expander Card Output States
