 Error Code: Error codes in the error log.
 Date & Time: The date and time the error occurred. The most recently occurring error is listed on the top.
 The last column shows the descriptions for the error.
(3) If the operation or operand exceeds the allowed range (SM0 = ON, stored in SR0) or an instruction inspection
error (SM5 = ON, stored in SR4) occurs, you can use the following method to see where the problem is.

When SM0 = ON, check the value in SR1 to see the error step. SR1: The address of the operation error (32-bit).

When SM5 = ON, check the value in SR5 to see the error step. SR5: The address of the grammar check error
(32-bit).

Once you know the error step number, you can go to ISPSoft -> Edit -> Step positioning. Enter the error step
number and click OK. The system takes you to the position where the step went wrong.
