Job is running status

[corbin]

Hello! I'm trying to find out if a job is running or not. Specifically, the filename that is loaded. The trouble I'm having is that SV_JOB_IN_PROGRESS returns IO_LOGICAL_1 even when I'm running a warmup routine, and haven't actually started the job. Is there a way to differentiate this?

Thanks!

My code:

Code: Select all

        public static bool IsJobRunning(this CNCPipe pipe)
        {
            CNCPipe.Plc.IOState plcState = CNCPipe.Plc.IOState.IO_STATE_UNKNOWN;
            CNCPipe.ReturnCode rc = pipe.plc.GetPcSystemVariableBit(CentroidAPI.PcToMpuSysVarBit.SV_JOB_IN_PROGRESS, out  plcState);
            if (rc == CNCPipe.ReturnCode.SUCCESS)
            {
                return plcState == CNCPipe.Plc.IOState.IO_LOGICAL_1;

            } else
            {
                return false;
            }
        }

I'm also curious about this method on CNCPipe.State, but it is internal:

Code: Select all

        internal bool CheckIfJobIsRunning()
        {
            if (File.Exists("C:\\cncm\\loadcommand.txt"))
            {
                return true;
            }

            string command = "STATE_CheckIfJobIsRunning";
            m_parent.SendAndReceive(command, out var response);
            FromString(response, out var value);
            return Convert.ToBoolean(Convert.ToInt32(value));
        }

There is not currently a way to determine which specific job is running, only that a job is running. Checking SV_JOB_IN_PROGRESS or SV_PROGRAM_RUNNING are the best ways to determine that.

CheckIfJobIsRunning has been retooled into IsJobRunning for the upcoming v5.40 release. It does a more programmatic way of checking the same information, without having to query the board. This would be a faster call to make in the future but does not help your current issue.

Let me mull it over some and I will see what I can come up with for you.

Thanks! Is there a difference between SV_JOB_IN_PROGRESS and SV_PROGRAM_RUNNING? I haven't poked around at SV_PROGRAM_RUNNING.

Maybe one could indicate the GCode file is running, and another could indicate that anything else is running (ie: macros via the VCP, MDI, etc)?

SV_PROGRAM_RUNNING is 1 if in the MDI screen or a job is in progress
SV_JOB_IN_PROGRESS is 1 if a MDI command is running (not just idly sitting there) or a job is in progress

For the next release, I added Job.GetCurrentlyRunningJob(out string current_job) which will give the current running job, subprogram, api command, mdi, or no job running.

Thanks! I'll check it out when I move to the next rev.

Below is my ugly heuristic hack that is working for now...

Code: Select all

            // HACK! It is hard to tell if we are running a warmup macro or something else. so, this is a heuristic to determine that, which may not be right
            if (newJobIsRunning && newJobIsRunning != _jobIsRunning)
            {
                int current_line_number = 0;
                int program_number = 0;

                _pipe.state.GetCurrentStackLevelZeroLineInfo(out current_line_number, out program_number);
                int stack_level = 0;
                int tempLine = 0;
                int tempProgram = 0;
                _pipe.state.GetCurrentLineInfo(out tempLine, out tempProgram, out stack_level);
                // If we are on line 1 of the current main program...assume we really haven't started, assuming we are deeper in the stack.
                // This makes a huge assumption that the first line of a program isn't something that calls a macro of some sort...which it might.
                if (stack_level > 0)
                {
                    if (current_line_number == 1)
                    {
                        newJobIsRunning = false; // Probably a macro...but like i said, this is a guess!
                    }
                }
            }
