;------------------------------ Description ------------------------------
;This program performs four different tests on a part:
;Test 1 is used to measure torque of a rotating part or assembly
;Test 2 is used to apply constant torque and measure deflection of a part
;Test 3 is used to apply constant torque and measure velocity
;Test 4 is used to measure bi-directional deflection of an assembly
;Outputs are used to signal if ready for a test and if the part passes or
; fails. The operator activates a start input when the part is loaded.
;A serial interface to a host computer is used to transmit test results and
;accept test parameters.
;
;-------------------------- G Variables used -----------------------------
ASSIGN Torqueconst G1 ;Motor torque constant to convert measured motor
; current in amps to torque
ASSIGN Testnumber G2 ;Determines which test to perform
ASSIGN Testvel G3 ;Move velocity for torque measurements
ASSIGN Testdelay G4 ;Delay time before making measurements to allow
; system to stabilize
ASSIGN Currentlimit G5 ;Current limit used for some tests
ASSIGN Normalcurrent G6 ;Default current limit
ASSIGN Maxtorque G7 ;Maximum torque tolerance
ASSIGN Mintorque G8 ;Minimum torque tolerance
ASSIGN Maxdistance G9 ;Maximum distance tolerance
ASSIGN Maxvel G64 ;Maximum velocity tolerance
ASSIGN Minvel G63 ;Minimum velocity tolerance
;Result storage variables
ASSIGN Test1torque G10 ;Calculated torque result for test 1
ASSIGN Test2deflect G20 ;Measured position deflection for test 2
ASSIGN Test3velocity G30 ;Measured velocity for test 3
ASSIGN Test4deflect G40 ;Measured position deflection for test 4
;-------------------------- V Variables used -----------------------------
ASSIGN Meascurrent V1 ;Used to store measured current
ASSIGN Startpos V2 ;Used to capture starting position of test
ASSIGN Targetpos V3 ;Used to calculate target position of move
ASSIGN Test4pos1 V4 ;First engaged position for test 4
;-------------------------- B Variables used -----------------------------
ASSIGN Testcomplete B1 ;Used to signal host that data is available
;-------------------------- F Variables used -----------------------------
ASSIGN Starttimer F1 ;Used in scanned event to start timer
ASSIGN Timerdone F2 ;Used in scanned event to indicate timer is done
;-------------------------------- Inputs ---------------------------------
ASSIGN Starttest I4 ;Start the test
ASSIGN Stoptest I13 ;Stop the test
;-------------------------------- Outputs --------------------------------
ASSIGN Pass O1 ;Indicates the part passed the test
ASSIGN Fail O2 ;Indicates the part failed the test
ASSIGN Ready O3 ;Indicates the test is complete and ready for the
; next part
ASSIGN Setuperror O4 ;Indicates setup error
;---------------- Optional Accessories Required/Supported ----------------
;Operator Terminal - SUPPORTED
;The program can be modified to print messages to the operator terminal
; screen and allow key press control over the tests.
;---------------------------- Scanned Events -----------------------------
S1: IF Stoptest = ON Stop=ON;If Stoptest input on, stop the program
S2: TMR1 Starttimer = ON Timerdone = ON;Generic Timer routine
