MCO 305 Design Guide
Each APOSS Window can be connected to only one controller at a time and each APOSS program can be
edited by only one APOSS Window at a time. Hence, if you want to execute the same program on several
controllers, then use one of the following methods:
1. Use Development → Select Controller to select and connect to the first controller. Then use
Development → Execute to download and start the program executing on the controller. Once the
program is executing, then use Development → Select Controller a second time to select and
connect to the second controller. This will disconnect from the first controller but leave the program
executing. Then use Development → Execute to download and start the program on the second
controller. Repeat the process for as many controllers as desired.
2. If the program is to be started on several controllers that all share the same network connection,
(e.g. in a field bus) then Development → Download all can be used. This allows the program to be
compiled, downloaded, saved in permanent controller memory, and started, all in a single user
operation.
Break [Esc] and Continue
Click on Development → Break or press [Esc] in order to stop any program currently executing on the
controller.
NB!:
If an executing program is aborted while the drive is rotating, then the drive will slow down with
the maximum allowed deceleration.
Development → Break all can be used to stop the execution of multiple controllers at the same time.
Click on Development → Continue, in order to continue a program which was just aborted. In doing so any
positioning processes which were interrupted will be completed.
If a program with an error message was aborted, you can Continue it again with this function once you have
removed the error and/or erased the error message.
Messages -> Log file
This function can be used to start the logging of all messages displayed in the Communication Window to a
file. Similarly, Stop logging will stop the logging of messages.
Messages are cached and may not always be written to the file immediately. As a result, if the file is edited
or copied while logging is in progress, then the most recent messages will not always be included. To avoid
this, use the Update Log file command immediately before editing or copying the file. This will force all
messages cached up until this point to be written to the file.
Note that Stop logging and Update Log file will be enabled only if logging has been started.
Debugging Commands
The following commands are designed to be used to assist the user in debugging newly developed
programs. For detailed information about debugging and the use of these commands, please see Debugging
Programs.
Prepare Singlestep
This command will "prepare" both the APOSS-IDE and the controller for debugging. This includes compiling
the program in "debug" mode, inserting breakpoints, and downloading the program.
Go
This command will start execution of the program at the current program line and continue executing until
the next "user breakpoint" is reached.
Singlestep
This command will execute a single program line and stop at the next line. The next line is not executed.
