IDEC SmartRelay functions
128 IDEC SmartRelay Manual
4.4 Special functions list - SF
When you create your circuit program in IDEC SmartRelay,
you find the special function blocks in the SF list.
You can invert the inputs of SFs individually, that is, the
circu
it program converts a logical ”1” at the input into a
logical ”0”; a logical ”0” it converts into a logical ”1”. An
example of the program code is found in Chapter 3.6.3.
The table also specifies whether the
relevant fun
ction can be
set retentive (Rem). The following SFs are available:
