5. Programming on the device
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 but-
ton to move to the function block number
Press the OK button.
The display switches to the function block editor. Here you normally define all func-
tion 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
function 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 to be made to reference points (constants). You must at least confirm the +/-
character with the OK button.
Parameter sets can only be enabled or protected via the
FUNCTION RELAYS menu, or via the circuit diagram with the
“+” enable and with “–” inhibit parameter set characters.
