OPCA Keyword

Besides specifying the command to be issued in response to the request, you must also tell TWS Automation:

  • The status you expect the subsystem to assume as a result of this command
  • The time interval within which the subsystem must assume this status

This is done with the OPCA keyword. The following panel continues the example of Figure 1.

Figure 1. Specifying Expected Status and Time Interval
 Code 1          Code 2          Code 3          Value Returned                 
 START                                           UP,2,RMFUTMER                  
 OPMSG                                           UP,1,                          
 STOP                                            DOWN,2,                        

Here, the request is specified in the Code 1 column. The Value Returned column contains the expected status, the time interval (in minutes), and optionally a timer name. The Code 2 and Code 3 columns are intended for eventual request parameters and consequently left blank in this example.
