Setpoints
Do not perform repeated writing of setpoints (e.g. do NOT have a MODBUS ’watchdog’ system where PLC
periodically writes down a figure into register and then reads the figure). The setpoints are stored in
EEPROM memory, which can be overwritten up to 100 000 times without risk of damage or data loss,
however it may become damaged, when allowed number of writing cycles is exceeded!
The issue with EEPROM memory limit is resolved from ID-DCU MARINE firmware version 2.2, setpoint
registers were moved into another memory part of the controller.
Password
There are three levels of password protection.
0. User level allows change of non-protected setpoints only.
1. Operator level allows change of setpoints protected by Operator level.
2. Master level allows change of setpoints protected by Operator and Master level.
3. Supervisor highest level allows all setpoints or configuration changes, firmware upgrade.
Hint:
The asterisk mark “*” appears before a setpoint name (on controller screen) if the setpoint is password
protected.
The asterisk mark is removed only when the password is set from controller’s front panel.
The asterisk mark is still visible on controller screen even if the password is set from InteliMonitor.
Even though one level may have been set from the front panel, the affected setpoints are not accessible
from InteliMonitor (direct or Modem) until this level is set in InteliMonitor (direct or Modem). Setpoints opened
from front panel are automatically closed 15 minutes after the last key has been depressed or when wrong
value of setpoint is set.
It is possible to protect remote Start, Stop commands from InteliMonitor as well. This three level command
protection can be configured from DriveConfig.
EnterPassword
Password is a four-digit number. Only setpoints associated with the entered password level can be modified.
Use or to select the desired password and then hit enter.
ChangePassword 1
ChangePassword 2
ChangePassword 3
Hint:
Any password can be changed once that level password or higher has been entered if the change is
made from InteliMonitor PC tool.
Password level 3 must be entered at first to change any password if the change is made by
controller front panel buttons.
To change password protection of Setpoint or Command:
Open DriveConfig
Select Setpoints or Commands window
Set desired protection level: 0 or 1 or 2 or 3
