Parameters for Counters
The parameter display for counters is used to change the counter
setpoint value and to enable or disable parameter access.
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.
The counter relay counts between 0 and 32000.
When the Pico is in Run mode and the value of 32000 is reached, this
value is retained until the count direction is changed. If the value of
