M_Err/M_ErrLvl/M_Errno
[Function]
Returns information regarding the error generated from the robot.
M_Err : Error occurrence condition
M_ErrLvl : The level of the occurrence error
M_Errno : Error number
[Format]
Example) <Numeric Variable>=M_Err
Example) <Numeric Variable>=M_ErrLvl
Example) <Numeric Variable>=M_Errno
[Terminology]
<Numeric Variable>
[Reference Program]
1 *LBL: If M_Err=0 Then *LBL
2 M2=M_ErrLvl
3 M3=M_Errno
[Explanation]
(1) Normal programs will pause when an error (other than cautions) is generated. The error status of the
controller may be monitored using this variable for programs whose startup condition is set to ALWAYS
by the SLT* parameter. The program set to ALWAYS will not stop even when an error is generated from
other programs.
(2) If two or more errors occur, returns the information on the high error of the error level most.
(3) The error level which M_ErrLvl returns, and its meaning are shown below.
