Process sequence
The ideal programming technique for the required application
Q Series supports all major sequence control programming
methods in use today. These include Ladder Diagram (LD),
Instruction List (IL), Sequential Function Chart (SFC), Function
Blocks (FB) and Structured Text (ST). Additionally, the high
performance Q Series sequence CPUs allow multiple programs
to co-exist in the processor, and can be executed in variable
ways, further improving the performance of the controller.
Q Series offers the ability to fix the program execution scan at a
predetermined interval between 0.5ms-60s (High permance
model QCPU and process CPU). This allows the determinism of
a system’s execution to be improved for applications where
execution timing is critical. To further improve response to brief
events, a 0.2ms interrupt function is also available.
Sequence Program Environment
GX Configurator frees the system designer from having to waste
engineering time on writing and debugging code just to
configure the controller’s special function modules. All modules
such as analog, communications and motion control have GX
Configurator tools associated with them that reduce
configuration to a simple menu based system. Further, the
automatic refresh capability of the Q Series insures that using
GX Configurator to monitor system configuration during
maintenance always shows real time system data.
Program-free Initial Settings
Sequential Function Chart (SFC) is an industry standard
programming method that improves the readability of a program
via a graphical representation similar to a flowchart. Q Series
fully supports SFC, offering you the chance to simplify the
organization of your programming by using multiple program
states to control and sequence the operation of your application.
During maintenance, SFC can also be used to follow the
operation of a system graphically, improving the productivity of
maintenance personnel.
