Pico System Settings 6-7
Change Parameters Pico allows you to change function relay parameters such as timer and
counter setpoints without having to call up the circuit diagram. This is
possible regardless of whether Pico is running a program or is in Stop
mode.
1. Press Ok to switch to the main menu.
2. Start the parameter display by selecting PARAMETER.
A complete parameter set is shown. In the example, these are the
parameters for a timing relay T1.
The following requirements must be fulfilled for a parameter set to be
displayed:
• A function relay must have been included in the circuit diagram.
• The parameter set has been enabled for access, indicated by the
’+’ character at the bottom right of the display.
Use the PARAMETER menu to access and modify accessible parameter
sets. Parameter sets for which access is not enabled are not displayed.
Pico therefore allows you to protect parameters with the use of a
password. You can enable or disable parameter access using the
parameter ’+’ or ’-’ characters respectively in the circuit diagram.
1. Use up or down arrows to scroll through the parameter sets. The
cursor must be located on the identifier of the function relay, in
this case T3.
2. Press Ok.
3. Use up or down arrows to select the parameter required.
4. Change the values for a parameter set:
• press Ok to enter the Entry mode.
• use left and right arrows to change decimal place.
• use up and down arrows change the value of a decimal place
• Ok Save parameter or Esc Retain previous setting.
5. Press Esc to leave the parameter display.
The parameter display is opened via the PARAMETER menu. ’{’ coil
terminals for counters and timers are not displayed here, even if they
have been programmed.
