4.1 Device commands (C00002/x)
This chapter describes the device commands which are provided in the subcodes of C00002
and can be carried out using the keypad or, alternatively, the »Engineer« when an online
connection has been established.
The device commands serve, among other things, to directly control the controller, to
organise parameter sets, and to call diagnostic services.
Regarding the execution of the device commands, a distinction is drawn between:
Device commands which have an immediate effect on control (e.g. "Activate quick
stop")
– After being called in C00002/x
, these device commands provide static status
information ("On" or "Off).
Device commands with longer execution duration (several seconds)
– After being called in C00002/x
, these device commands provide dynamic status
information ("Work in progress 20%" "Work in progress 40%", etc.).
– The execution of the device command has not finished successfully until the "Off /
ready" status information is provided in C00002/x
.
– In the event of an error, the "Action cancelled" status information is provided in
C00002/x
. In this case, further details can be obtained from the status of the device
command executed last which is displayed in C00003
.
Stop!
Before the supply voltage is switched off after a device command has been
transmitted via C00002/x
, the device command must be checked for successful
completion on the basis of the status information provided in C00002/x
!
• This is of particular importance for device commands which save data to the
memory module of the device. Incomplete storage processes may lead to
data inconsistencies in the memory module.
Note!
• Before activating device commands by a master control, wait for the "Ready"
signal of the controller.
• The device will reject a write process to C00002/x
if the value is >1 and issue
an error message.
• C00003
displays the status of the device command that was executed last.
