Linking Of Bits - WAGO I/O SYSTEM 750 750-671 Manual

64 • 750-671 [Steppercontroller]
Configuration
The universal filter functions FILT1 ... FILT8 possess a special status. The
inputs for these filter functions are linkable bits that can be linked to any other
bit. A query of these bits, on the other hand, provides information about the
status of the filter. As a result, these bits represent a function between inputs
and outputs.
The table containing the available bits is given in the appendix in section 3.4,
„Bit field for I/O driver".
The following conventions apply:
 Source bits are assigned numbers 0 to 127 and may not be used as target
 Target bits are assigned numbers 128 to 255 and may also be used as
 References are stored in the configuration table. The names of the table
 The standard link between the source and target is entered in the column
2.1.2.10.5

Linking of Bits

The expanded parameters are set using pointers (indices). The address for
these pointers indicates a corresponding address in the bit I/O field. Allocation
using names is also provided. "Ptr_nnn" indicates the variable "nnn".
Actual allocation is conducted using the content of the pointer.
The figure below illustrates allocation with an example of motor shutdown
using Stop1_N and Stop2_N.
