5.7 Remote Commands
Setup and processing at the 7AF can be guided by either a local operator or by a Host computer. This section describes the
remote commands available to the Host.
Much of the behavior of the 7AF and its acceptance of remote commands is directed by requirements of the Control State.
For a complete description of the Control State, please see section 5.2, "Control States".
The 7AF will accept remote commands only when the Control State is Remote. While in the Local state, the Host can not
put the Equipment into Remote, this must be done by an operator at the Equipment.
The Host has the ability to configure whether the Equipment will transition to Remote or local as a default upon entering
the On-Line state from Off-Line. This is done by setting The ONLINESUBSTATE Equipment Constant (VID 44) to 4
(Local) or 5 (Remote).
Once in the Remote state, the Host has the authority to issue any of these remote commands and they will not be rejected
because of an invalid control state. Commands may be rejected for other reasons (trying to start a process with no
material loaded, etc.).
While in Remote state, the Operator still has the ability to issue commands and change the control state. If the operator
issues a command while in Remote state, the 7AF will send the OperatorCommand collection event if enabled (CEID 11).
When the Operator "grabs" control away from the Host by changing the Control State to not Remote, the 7AF will send
either the CONTROLSTATELOCAL (CEID 13) or EQUIPMENTOFFLINE (CEID 5002) event to the Host. The Host
also has the ability to put the Equipment into a Local state by sending the LOCAL remote command while in Remote state.
5.7.1 S2F41 Commands
The general format for remote commands using the S2F41 message is:
S2F41 [W] * H->E
<L [2]
<A RCMD> * Remote command string
<L
<L [2]
<A CPNAME> * Command Parameter Name
<CPVAL> * Command Parameter Value
>
...
>
> .
The following commands may be sent by the Host to the 7AF.
5.7.1.1 START
This command starts processing on the 7AF assuming all proper initialization has taken place and material is present. The
command, “BEGIN-AUTO”, must be issued successfully to set the 7AF to Process State 2. Also, “GRIND-TYPE” must
be successfully issued to select the grind type.
