Here is an example from one of the IOCs at a beamline I support:

   $ cat PI_GCS2.cmd
   dbLoadTemplate("PI_GCS2.substitutions")
   drvAsynIPPortConfigure("C867_ETH","192.168.1.7:50000",0,0,0)
   # Turn on asyn trace
   asynSetTraceMask("C867_ETH",0,3)
   asynSetTraceIOMask("C867_ETH",0,1)
   # PI_GCS2_CreateController(portName, asynPort, numAxes, priority, 
stackSize, movingPollingRate, idlePollingRate)
   PI_GCS2_CreateController("C867", "C867_ETH",2, 0,0, 100, 1000)
   # Turn off asyn trace
   asynSetTraceMask("C867_ETH",0,1)
   asynSetTraceIOMask("C867_ETH",0,0)

   $ cat PI_GCS2.substitutions
   file "$(MOTOR)/motorApp/Db/asyn_motor.db"
   {
   pattern
   {P,        M,                    DTYP,    PORT, ADDR,      DESC, 
EGU,  DIR,  VELO,  VBAS,  ACCL,  BDST,  BVEL,  BACC,  MRES,  PREC, 
DHLM,  DLLM,  INIT}
   # U-651.03
   {IOC:,  "m1",  "asynMotor",  "C867",    0,  "Motor 1", deg,  Pos, 
5,     0,    .2,    0,      1,    .2,  0.0005,  4,     0.0,   0.0,  ""}
   # U-624.03
   {IOC:,  "m2",  "asynMotor",  "C867",    1,  "Motor 2", deg,  Pos, 
5,     0,    .2,    0,      1,    .2,  0.0020,  4,     0.0,   0.0,  ""}
}

I'm creating examples for the drivers that lack them as I move the 
drivers from the motor repositories into their own repositories.  The 
PIGCS2 support hasn't been moved yet, but there is a good chance it'll 
be a standalone repository by early next week.

These example IOCs will require help from the community, since at the APS we don't have all of the types of controllers that are supported, so we can't test examples.
