6.3 System setup menu
The system setup menu contains the main configuration settings for the sc1000
controller.
The system setup menu can include following items:
• OUTPUT SETUP
• CURRENT INPUTS
• RELAY
• NETWORK MODULES
• GSM-MODULE
• DEVICE MANAGEMENT
• DISPLAY SETTINGS
• BROWSER ACCESS
• STORAGE CARD
• SECURITY SETUP
The availability of the menu items depends on the installed internal plug-in expansion
cards or external DIN rail modules.
6.3.1 Output setup menu
Note: This menu appears only if an output card is installed in the sc1000 controller.
The content of the output setup menu depends on the selected use/working mode:
Linear/Control or PID Control. The current output card can be used with the output
current linearly dependent to a process value or with the output current working as a PID
controller.
LINEAR CONTROL
In this working mode the output current is linearly dependent to a process value after it
has been processed by the internal formula parser (if prompted).
PID CONTROL
In this working mode the current output module generates a current output which tries to
control the process value. The PID controller controls the process value to be equal to
the set point when a disturbance changes the value of the process value or a new set
point is set.
The output current can be in a working range of 0
–20 mA or 4–20 mA. The highest output
current is 22 mA. If necessary adjust the output current with an offset and a correction
factor to enhance the accuracy. By default these two parameters are set to “0” (offset)
and “1” (correction factor).
