Function descriptions
Double-word connectors (SW 1.9 and later)
Double-word connectors are connectors with a 32-bit value range (i.e. LOW word and HIGH word with
a double-word value range of 00000000Hex to FFFFFFFFHex ).
-100 % to +100 % corresponds to connector values of C0000000 Hex to 40000000 Hex
(= -1073741824 to +1073741824 decimal). This means that the value range in the upper 16 bits
(HIGH word) of a double-word connector is the same as for a "normal" connector (C000 Hex to 4000
Hex or -16384 to +16384 decimal for -100 % to +100 %). The extra 16 bits in the LOW word as
compared to a "normal connector" afford, therefore, an improved resolution of the connector value by
a factor of 65536. For information about how to use double-word connectors see also the section in
"The following rules apply to the selection of double-word connectors" below.

Binectors
All binary output quantities and important binary output signals of the function blocks are available as
"Binectors" (connectors for binary signals). Binectors can assume states log. "0" and log."1". The
quantities accessed via binectors correspond to output signals or measuring points in a digital circuit
and are identified by their "Binector number" (e. g. B0003 = binector 3).
Special cases: B0000 = Fixed value log."0"
A list of available binectors can be found in Section 12.
Example: The status of terminal 36 is available at B0010 and, in inverted form, at binector B0011
(Section 8, Sheet G110)

Selection switches, connections
(see also Section "Data sets")
The inputs of function blocks are defined at "selection switches" by setting the appropriate selection
parameters. The input is defined by entering the number of the connector or binector to be applied as
the input quantity in the parameter for the relevant selection switch.

Selection of a connector
Parameter number = P750, factory setting = 0 (i. e. fixed value 0%)
Selection of a binector
Parameter number = P704, factory setting = 0 (i. e. fixed value 0)
Selection of connectors ("indexed" parameter with 4 indices)
Parameter number = P613, factory setting = 1 (i. e. fixed value 100%; this factory
setting applies to all the indices of P613)
Selection of connectors ("indexed" parameter with 4 indices)
Parameter number = P611
Factory setting for index .01 = 277 (i. e. connection with connector K0277)
Factory setting for indices .02 to .04 = 0 (i. e. fixed value 0%)
