In this training we will review the types of signals to search for, as well as how to utilize Technician Mode of Compass.
Locating a Value-Add Signal
Tracker's purpose isn't solely that of a conventional data logger. Instead, it serves to track and validate value creation within the production process. Consider this example: knowing that a Press brake is turned on doesn't inherently contribute value, as Compass already tracks the overall time spent on a Work Order. The true value comes when a part is actually bent. However, in cases where Press brake Operators need to pulse the Downstroke multiple times to achieve a single bend, using the Upstroke of the machine offers a cleaner representation of a single operation.
Another case in point involves a CNC Plasma Cutting table. Instead of closely monitoring the movement of the gantry, which might not directly contribute value to the production process, a more meaningful signal would involve tracking the torch itself. This signal indicates that actual product cutting is occurring, thereby adding tangible value to the process.
Tracker's utility extends beyond equipment; it can also be applied to intelligent jigs and fixtures. This can be achieved by using limit switches in series, effectively confirming that all contact points have been met. This integration ensures that the fixture is set up correctly before proceeding with the production process.
To access Technician Mode in Compass, use the Access Key '1111' when logging in. Once inside, click on the "EDIT" button located in the top-right corner of the screen to initiate changes. If no machine signals have been set up, click the green '+' sign to add them.
Performing this action will open a module where you can enter a Machine Alias. This should be a distinct and defining name for the piece of equipment. For instance, if you have two press brakes named PB1 and PB2, the Alias should be something like PB1 or PB2, rather than a general term like "Press brake."
Next you will be prompted to enter a Machine Type. Continuing the previous example, this is where you would use the more generic category of Press brake.
After creating the Machine, the next step is to assign the signals that it will be monitoring. Click on the "ADD SIGNAL" option to configure these signals.
You have the option to choose from 7 different signal types, which can be used independently or in conjunction with others:
- Next - when sensed will press the NEXT button on Compass
- In Cycle - will notify Compass Value is being created
- E Stop - will notify Compass there is an Emergency Stop
- Pass - will notify Compass that a Quality Check succeed
- Fail - will notify Compass that a Quality Check failed
- Close Job - will notify Compass to conclude an Instruction-Less job
- Pause - will notify Compass to open the Pause Screen
Details represent the trigger state of the signal. If the signal is normally high, set to 0. If it is normally low, set to 1.
The "Return from Break" is a toggle option. If this signal is sensed during a Scheduled Break, Compass will automatically resume Production Mode. If you leave this option disengaged, Compass will continue to stay in Scheduled Break Mode regardless of whether a signal is sensed or not.
By clicking on INPUT you will be presented all ports of Tracker to select which the signal has been physically connected to.
When all conditions are set, you can either Add another signal by pressing ADD SIGNAL or to save changes by pressing SAVE at the top-right.
Unlike Machine Signals, which are recorded actions that can appear in reports, Tracker Signals are not recorded actions. Instead, they are used to assist operators in navigating Compass.
Creating Tracker Signals is similar to Machine Signals, the exception it does not allow the Return from Break.
In Cycle is not available for Tracker Signals, and instead has 2 others:
- Proximity - will notify Compass that an Operator is not present and press Pause
- Photo - for Instructions requiring Photo Capturing, this will activate the picture to be taken
I stare at computer screens more than anything else, I get teased for my 3 monitors. At home me and my friends are overly obsessed with video games, especially Rocket League.
