Entering function block parameters
If you enter the coils or contacts of a function block, the inputs/outputs of the function
block are displayed that you can parameterize. The parameters can be entered via the
function blocks menu.
The meaning of these parameters is explained under each function block type.
Entry:
The first part of the parameter set of a counter C01 is displayed.
Move the cursor > over the + character to the value input behind
>SH
:
>SH
means: Function block input upper counter setpoint value.
The + character means that the parameters of this timing relay can be modified
using the PARAMETERS menu.
Change the upper counter setpoint to 10:
Use < > to move the cursor onto the tens digit.
Use the ↑ and ↓ buttons to change the value of the digit.
Press OK to save the value and ESC to return to the circuit diagram.

Configuring the parameter for T01:
The timing relay works like a flashing relay. The function is set on the top right beside
the number in the parameter display.
The time base is set to the right of the “flashing” function. Leave the time base set
to S for seconds.
Move the cursor to the right over the + character in order to input the time
SETPOINT value I1.
If you enter the same setpoint value at I1 and I2, the timing relay operates as a syn-
chronous flasher.
The + character means that the parameters of this timing relay can be modified using
the PARAMETERS menu.
