* ‘SP’ instruction was detected in the subprogram.
(Cause) Data was already present before SP instruction.
* There is no ‘SPE’ instruction at the bottom of the subprogram.
(Cause) Data remained after SPE instruction.
- There is an undefined instruction.
(Cause) A code of other than a step sequence instruction is stored.
* Specified value for a parameter of the xxxx instruction is outside the range.
(Cause) The parameter of the xxxx instruction falls outside the predetermined range.
* An illegal program number is specified for the xxxx instruction.
(Cause) The program number specified for the xxxx instruction falls outside the
predetermined range.
- An illegal label number is specifed for the xxxx instruction.
(Cause) The label number specified for the xxxx instruction falls outside the
predetermined range.
- The label of xxxx is used twice or more.
(Cause) A label number is duplicated within a single subprogram.
* The number of label exceeds the limit.
(Cause) An attempt was made to exceed the maximum number of labels that can be
defined in a single subprogram.
* Illegal ‘DSTEP’ instruction was detected,
(Cause) The DLBL instruction is not defined. Alternatively, the definition of the DSTEP
instruction is duplicated.
* LADDER execution time at the 1st level is too large.
(Cause) The overall execution time of the first level exceeds the predetermined limit.
(Action) Reduce the size of the program of the first level.
* The coil number specification of JMP instruction is not allowed.
.
(Cause) The parameter of the JMP instruction (number of coils to be jumped) is other
than 0.
(Action) Specify 0 for the parameter.
- The coil number specification of COM instruction is not allowed.
(Cause) The parameter of the COM instruction (number of coils to be controlled) is
other than 0.
(Action) Specify 0 for the parameter.
