Woodward has launched hardware and software updates to address many CIP requirements; however, complete NERC/CIP compliance involves more than the controls and is dependent on plant infrastructure and procedures. The physical security remains the user’s responsibility.
Discrete Outputs
•• Programmable
◦ The discrete output has been assigned a default function using the ◦
LogicsManager.
◦◦ The following text describes how these functions are assigned using the
LogicsManager.
◦ It is possible to change the function of the discrete output if required. ◦
◦ The following description of the outputs, labeled with "programmable", refers to ◦
the pre-configuration.
•• Fixed
◦◦ The discrete output has a specific function that cannot be changed depending
upon the configured application mode.
◦ The discrete output cannot be viewed or changed in the LogicsManager. ◦
◦ However, the discrete output may be programmable in some application ◦
modes.
The discrete outputs can be "programmable" or "fixed" depending on the application
mode.
CAUTION!
Uncontrolled operation due to faulty configuration
The discrete output "Ready for operation" must be wired in series with an emergency
stop function.
This means that it must be ensured that the generator circuit breaker is opened and the
engine is stopped if this discrete output is de-energized.
If the availability of the plant is important, this fault must be signaled independently from
the unit.
CAUTION!
Uncontrolled operation due to unknown configuration
The circuit breaker commands must be checked before every commissioning because the
relays can be used for different applications and can be assigned to various functions.
• Make sure that all relay outputs are configured correctly
