Functions
Programming in LADDER language
Programming in FBD language
"Simulation" mode
"Monitoring" mode
Zelio Logic smart relays
Compact and modular smart relays
“Zelio Soft for PC” programming software
“Zelio Soft” software allows:
b programming in LADDER language or in function block diagram language (FBD),
b simulation, monitoring and supervision,
b uploading and downloading of programs,
b output of personalised files,
b automatic compiling of programs,
b on-line help.
“Zelio Soft” software monitors applications by means of its coherence test function.
An indicator turns red at the slightest input error. The problem can be located by
simply clicking the mouse.
"Zelio Soft" software allows switching, at any time, to any of the 6 application
languages (English, French, German, Spanish, Italian, Portuguese), and editing of
the application file in the selected language.
"Zelio Soft" software allows Text function blocks to be configured, which can then be
displayed on all smart relays which have a display.
2 test modes are provided: simulation and monitoring.
“Zelio Soft” simulation mode allows all the programs to be tested, without the smart
relay, i.e.:
b enable discrete inputs,
b display the status of outputs,
b vary the voltage of the analogue inputs,
b enable the programming buttons,
b simulate the application in real time or in accelerated time,
b dynamically display (in red) the various active elements of the program.
“Zelio Soft” monitoring mode makes it possible to test the program executed by the
smart relay, i.e.:
b display the program "on line",
b force inputs, outputs, control relays and current values of the function blocks,
b adjust the time,
b change from STOP mode to RUN mode and vice versa.
In simulation or monitoring mode, the monitoring window allows the status of the
smart relay I/O to be displayed within your application environment (diagram or
image).
