Rules of execution of a network
The execution of a network is carried out column by column, from the left to the right.
A network contains graphic elements all connected to each other by linking elements (except for the potential bars).
By conforming to this execution sequence, the system :
evaluates the logical state of each interrogation, according to the current value of the internal objects of the application or for the state of the inputs of the modules of inputs/outputs acquired at the beginning of a cycle ;
executes the actions associated with the functions, with the blocks functions and with the sub-programs ;
updates the bits objects associated with the coils (the update of outputs is made at the end of the cycle when all the networks are analyzed).
Execution and analysis of a network in the reverse sense is not allowed because the network is executed column by column from the left to the right.
