How to write a Controller
Driver: Controller:
#MOVE:X,Y,Z&
#MOVE:0&
#MOVE:X,Y,Z&
#STOP&
#STOP:0&
Figure 6-68: Asynchronous timing examples.
In Example A in Figure 6-68 a normal MOVE command is send from the
driver to the controller, when the traverse is in position the controller sends
back a MOVE in return. In Example B Figure the driver sends a MOVE
command, the driver then sends a synchronous STOP command and the
controller must respond this with a STOP in return. Note that the controller
does not need to send a MOVE in return in example B when STOP is called.
The initialisation string can be used to send information to the traverse
controller. The generic traverse protocol is small and precise and will fulfill
most users demands. Users who want more control or use different traverses
can save a initialisation string along with a BSA Flow Software project,
telling how to control the traverse for that particular project. The user must
format the string in a way that they can unpack in the controller. E.g. if the
traverse should use a particular speed during the current project the
initialisation string could look like this: "SPEED:1000".
The controller is a piece of software on a remote computer controlling the
actual traverse system. The two computers must both have a free RS232 port
installed. Set the communication ports on both computers to the following
settings:
Baud Rate 9600
Data Bits 8
Parity None
Stop Bits 1
Flow Control None
Table 6.5-3: RS232 Port Settings for Generic Driver.
The two computers must be connected using a serial null-modem cable. The
remote computer running the controller software can be any type of machine
running any kind of operating system (OS) supporting RS232
communication.
