Status attribute

Specifies the status values of an attribute. An attribute has one of the following status values:

Ready

Indicates that the command group is ready to process the next command, when the command attribute is set to True. A trigger attribute can initiate an MES transaction only when the status of the command group is Ready.

Busy

Indicates that the command group is currently processing a command in the middleware. Any command attribute that is set to True from the group, except the command attribute that initiates the call to the middleware, is rejected and is reset to False.

Error

Indicates that the last call to the middleware resulted in a error. The caller has to acknowledge the error by resetting the status to Ready, before processing/initiating the next command from this command group.

Done

Indicates that the last call to the middleware is successful. The status is reset to Ready when the Auto Reset command is set to True. This status is available when the instance of an object is set to Manual Reset mode.
