DIGITAL OUTPUTS
Digital
output (DO) generic symbol
The solid state digital and PWM outputs are only available on controllers with a DC voltage supply indicated by S XX VDC. All controllers with an AC voltage supply and those with a DC voltage supply and R XX VDC addresses have RELAY outputs (one is an off/on relay and the rest are normally open relays). The output units which supply an PWM signal can also supply a solid state digital type signal. The selection is made by the programmer, who can place one of the two symbols accessible in the OUT tab of the function bar on the unit.
The following aliases, which can be used to define the digital outputs of the application in the edit and supervision windows, can be selected in the Parameterisation box.
In edit mode, the symbols are displayed in the OFF state. In Simulation and Monitoring modes, when the outputs change to the ON state, a different image is displayed.
