Please do not use the output of an equation as input at the same time. Such a
con󰈡guration could decrease the performance of the interfaces.
Structure and description of the LogicsManager
Fig. 177: LogicsManager - function overview
• Command (variable)
A list of parameters and functions is provided for the command inputs.
Examples of the parameters that may be con󰈡gured into these commands are
generator undervoltage thresholds 1 and 2, start fail, and cool down.
These command variables are used to control the output function or relay.
Refer to ╚═▷ “9.3.4 Logical Command Variables” for a complete list of all command
variables.
• Sign
The sign 󰈡eld can be used to invert the state of the command or to 󰈡x its output to a
logical true or false if the command is not needed. Setting the sign to the NOT state
changes the output of the command variable from true to false or vice versa.
• Operator
A logical device such as AND or OR.
• (Logical) output
The action or control sequence that occurs when all parameters set into the
LogicsManager are met.
For a complete list of all logical outputs refer to ╚═▷ “9.3.3 Logical Outputs”.
[Sx] - Sign {x}
Value {[Cx]} The value [Cx] is passed 1:1.
NOT Value {[Cx]} The opposite of the value [Cx] is passed.
0 [False; always "0"] The value [Cx] is ignored and this logic path will
always be FALSE.
