5.6 Working with function blocks
Use the buttons to move the cursor to a free contact or coil field.
Press the OK button to switch to Entry mode.
Then use the cursor buttons to select the function block you want (e.g., a
timing relay with the T identifier).
While the function block identifier is flashing, press the OK button or the button
to move to the function block number
Press the OK button.
The display switches to the function block editor. Here you normally define all function
block parameters. As you have reached the function block editor via the circuit diagram
in this case, you can only set the basic parameters.
The figure on the left shows the function block editor of the Timing relay function block.
The basic parameters may vary according to the function block. All manufacturer func-
tion blocks have the basic parameter +/-. Through the +/- symbol you can switch the
parameter display on and off in operating mode RUN to allow (+) or prevent (-) changes
