5.4.9 Preset setting program
As previously stated (see the “5.4.6. Download of parameter values at PLC start”
section on page 48), during the initialisation process at the PLC start, B&R PLC
downloads to the encoder the parameter values that have been set next to the
entries in the
Device Specific Parameters
group.
If any value is set in the
Init value
line of the
PresetValue_I6003
parameter, it
is sent to the control node.
To execute the preset the value must be transmitted to the
6003 Preset value
object in the asynchronous phase via SDO when the encoder is in operational
state (
NMT_CS_OPERATIONAL
) and then execute the
Store parameters
function (see the
Store parameters
function on page 92).
You can set and execute the preset also by using the Preset sample task
provided by Lika Electronic (AsEPL Sample Task using the AsEPL library available
in Automation Studio).
To open the Preset sample task you must enter the Logical View window by
pressing the
Logical View
tab.
Scroll through the tree of the available EPLs, extend the
Source
directory and
select the
Preset
AsEPL Sample Task. Right-click the
Preset
AsEPL Sample Task
in the list, press the
Open
command first and then the
Watch
command.
