UNINTENDED EQUIPMENT OPERATION

  • Do not use the kernel for normal Plant SCADA operation. The kernel is only for diagnostics and debugging purposes.

  • Configure your security so that only approved personnel can view or use the kernel.

  • Do not view or use the kernel unless you are an expert user of Plant SCADA and Cicode, or are under the direct guidance of Technical Support for this product.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

When set a task checks if the Plant SCADA Kernel is working (i.e., Plant SCADA is not locked up) and terminates Plant SCADA runtime if the timeout ([Kernel]WatchdogTime) has been exceeded a number of retries ([Kernel]Retries).

This is a backup measure to allow redundancy from other I/O servers to be enabled if the Primary I/O server gets locked (for example, by incorrect user Cicode).

Allowable Values:

  • 0 - (Disable)

  • 1 - (Enable)

Default Value:

0
