Drawing a Circuit Diagram with Pico 4-27
Values between 0000 and 9999 are possible.
The symbol “
{” before DIR, CNT and RES indicates whether the coil function is
programmed in the circuit diagram.
The actual value is only displayed in Run mode. The parameter display can then be
called via the power flow display or via the PARAMETER option from the main
menu.
The coil symbol is not displayed if you select the parameter display via the
PARAMETER menu option.
Time Switch
All versions of Pico are equipped with a real-time clock except the units with the
“-NC” designation. The procedure for setting the time is described in Setting the
Time on page 6-8.
Pico has four time switches, providing a total of 32 switching times.
Each time switch has four channels which you can use to set four on
and off times. The channels are set via the parameter display.
The real-time clock has a back-up battery. This means that it
continues to run in the event of a power failure, although the time switch relays do
not operate. The technical data in Appendix A contains details of the battery
back-up time.
