START Command
START Command
The START command initiates the operation of an object. Successful completion of
the START command leaves the object either in a STARTED or STARTING state. The
use of this command is subsystem-specific.
This command is sensitive.
OUT file-spec
causes any SCF output generated for this command to be directed to the specified
file. The variable file-spec is defined on page 5-9.
object-spec
designates the objects to be started. The variable object-spec is defined on
page 5-2. If object-spec is omitted, the assumed object is started. (See
ASSUME Command on page 5-36.) The objects that can be started depend on
the subsystem.
SUB [ subobjtype ]
selects the subordinate objects the command affects. The variable subobjtype
can be a subordinate object type or one of the keywords ONLY, ALL, or NONE, as
explained under SCF Subdevices on page 3-5.
SEL [ NOT ] state
directs the command only at objects in the specified state or only at those not in
the specified state. Valid states are listed in Table 3-1 on page 3-7. The use of
this option is subsystem-specific.
Considerations
•
START might cause downloading of object code into a programmable controller.
•
Some subsystems reply to the command after the start is initiated; others reply
when the start is completed. Refer to the SCF reference manual for a specific
subsystem for details.
Examples
•
This example initiates the operation of a LINE object named $CP1:
-> START LINE $CP1
START [ /OUT file-spec / ] [ object-spec ]
[ , SUB [ subobjtype ] ] [ , SEL [ NOT ] state ]
