What is a Watchdog Timer in a PLC?
A Watchdog Timer ensures that the PLC program executes within a specified time limit. If the program exceeds this time, the Watchdog Timer triggers a fault to prevent system errors or unintended behavior.
What is a redundant PLC system?
A redundant PLC system includes a backup CPU that automatically takes over if the primary CPU fails, ensuring continuous operation and minimizing downtime.
How do I add expansion modules to a PLC?
To add expansion modules to a PLC:
What is a PID loop in PLC programming?
A PID loop is a control function used in PLC programming to maintain precise and stable process control.
What is retentive (non-volatile) memory in a PLC?
Retentive memory is a type of memory in a PLC that preserves stored data even after the device is powered off or restarted.
Can a PLC run without an HMI?
Yes. A PLC can operate on its own without an HMI, though an HMI is often used for easier monitoring and interaction.
Can I simulate my PLC program before downloading it?
Yes. With CICON, you can use the built-in simulator to test and configure your PLC program in a virtual environment before deploying it to physical devices.
How do I reset a PLC to factory settings?
In CICON, this can be done via: Online → PLC Reset → Factory Reset.
What programming languages are used for PLCs?
Common PLC programming languages include
