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.
