Configuration of the command chain
Using the values specified in the above table, the chain of commands of the
LogicsManager (for example: operating the relays, setting the flags, specification of the
automatic functions) is configured as follows:
[Ax] = ( ( [C1] & [S1] ) & [O1] & ( [C2] & [S2] ) ) & [O2] & ( [C3] & [S3] )

Programming example for the LogicsManager
Fig. 359: Programming example (ToolKit)
• Relay [R2] shall energize, whenever "Discrete input [DI 02]" is energized "AND" the •
control does "NOT" have a fault that is "Alarm class C" "AND" does "NOT" have a
fault that is "Alarm class D"
The logical command variables are grouped into different categories.
Part 1: LM variables (1 to 39)
Part 2: LM variables (40 to 79)
Part 3: AM and LM results (80 to 99)
Cascading: Use digital results
This digital results of AnalogManagers and LogicsManagers are available as
LogicsManager Variables additionally. Like the other LM Variables they can be used as
input signal for (further) AnalogManagers or LogicsManagers. The calculation of
cascading goes in the sequence from 80 to 99.
