Entering the CONDITION block
The condition block uses a structured text expression to specify a
condition to evaluate for the transition. Each line of structured text
begins with a single quote (‘).
CONDITION (LanguageType := STX)
‘<structured_text>
END_CONDITION
TRANSITION example
TRANSITION (ID := 14, X := 420, Y := 280, Operand := AlwaysTrue_002,
HideDescription := Yes, DescriptionX := 455, DescriptionY := 265,
DescriptionWidth := 0)
CONDITION (LanguageType := STX)
'1
END_CONDITION
END_TRANSITION
Entering Subroutine Calls
The subroutine calls let you pass values into and out of the SFC
routine. Subroutine calls follow this format:
SBR_RET (
ID := <
unique_identifier >,
X := <
internal_grid_x_location >,
Y := <
internal_grid_y_location >,
In := <“list”>,
Out := <“list”>)
END_SBR_RET
