AP (Adaptive Program)
Chapter overview
This chapter describes the basics of AP and instructs how to build an application. All needed parameters can
be found in the groups 83 to 86.
What is AP?
Conventionally, the user can control the operation of the drive by parameters. Each parameter has a fixed set
of choices or a setting range. The parameters make adapting of the drive easy, but the choices are limited. It
is not possible to customize the drive any further. AP makes customizing possible without the need of a
special programming tool or language:
−
AP is using function blocks,
−
DWL AP is the programming and documentation tool.
The maximum size of AP is 16 function blocks. The program may consist of several separate functions.
Features
AP of DCS550 provides the following features:
−
16 function blocks,
−
more than 20 block types,
−
password protection,
−
4 different cycle times selectable,
−
shift functions for function blocks,
−
debug functions,
o
output forcing,
o
breakpoint,
o
single step,
o
single cycle,
−
additional output write pointer parameter for each block (group 86) and
−
10 additional user constants (group 85) used as data container
How to build the program
The programmer connects a function block to other blocks through a Block Parameter Set. The sets are also
used for reading values from the firmware and transferring data to the firmware. Each Block Parameter Set
consists of six parameters in group 84 and a write pointer in group 86. The figure below shows the use of
Block Parameter Set 1 in the firmware (parameters 84.04 to 84.09 and 86.01):
−
Block1Type (84.04) selects the function block type.
−
Block1In1 (84.05) selects the source of IN1. A negative value means that the source will be inverted.
−
Block1In2 (84.06) selects the source of IN2. A negative value means that the source will be inverted.
−
Block1In3 (84.07) selects the source of IN3. A negative value means that the source will be inverted.
−
Block1Attrib (84.08) defines the attributes of the inputs.
−
Block1Output (84.09) provides the value of the function block output, which can be used further for other
input selections. The user cannot edit this parameter value.
−
The output value is also available in write pointer Block1Out (86.01). Block1Out (86.01) contains the
destination parameter, into which the value is written.
How to connect AP with the firmware
The outputs of AP need to be connected to the firmware. For that purpose, there are two possibilities:
−
The outputs, e.g. Block1Output (84.09), can be selected for further functions.
−
The output values are available in the write pointers, e.g. Block1Out (86.01). These parameters contain the
destination parameters, into which the values are written.
