Examples
6.4.5 Example of Function Block FB164
In the example, function block FBI 64 PER:POS works with the function blocks FB53 and FB54
and with data blocks DB160 and DB1 64. The following requirements must be met:
signal state "O" = indirect parameter assignment via FB54
signal state"1" = direct parameter assignment via FB53
The function block FB53 shows direct parameter assignment to FBI 64; FB54 shows indirect par-
ameter assignment. With indirect parameter assignment, the actual operands are stored in
DB160 from data word DW1 to DW7.
The example of indirect parameter assignment covers all possible modes, whereas the example
for direct parameter assignment is restricted to the following modes:
reference point approach
- JOG 1 and 2
- incremental relative
- read actual value and distance to go
- disable monitoring
- axis off
Function Block FB53 (Schematic Diagrams)
6.4.5.1
The function block FB53 shows the use of the function block FBI 64 with direct parameter assign-
ment via the block parameters. FBI 64 must be called once for each required mode.
