[D8415, D8414][D8435, D8434]
These devices store the step number of an instruction for the CF-ADP where an error has occurred.
1. Detailed contents
These devices store the step number of an instruction for the CF-ADP where an error has occurred.
When communication port ch1 is used, (D8415, D8414) stores the value.
When communication port ch2 is used, (D8435, D8434) stores the value.
If an error has occurred in two or more instructions, these devices store the step number of the instruction for
the CF-ADP where an error occurred first.
If no error has occurred, these devices store "-1".
2. Cautions on use
These devices store 32-bit data.
