M-logic
M-logic functionality is included in units with software versions 1.51 and forward. It is not an
option dependent function, but selecting additional options, such as option M12 which offers
additional digital inputs and outputs, can increase the functionality.
M-logic is used to execute different commands at predefined conditions. M-logic is not a PLC
but substitutes one, if only very simple commands are needed.
M-logic is a simple tool based on logic events. One or more input conditions are defined, and at
the activation of those inputs the defined output will occur. A great variety of inputs can be
selected, such as digital inputs, alarm conditions and running conditions. A variety of the outputs
can also be selected, such as relay outputs, change of gen-set modes and change of running
modes.
The main purpose of M-logic is to give the operator/designer more flexible possibilities of
operating the generator control system.
The M-logic is part of the PC utility software, and as such it can only be
configured in the PC utility software and not via the display.
The M-logic icon is not active as default – ‘Alt + F1’ activates M-logic.
