Condition
Can be used in standard specification.
Valid in ONLINE mode only.
The data becomes valid when EOP (∗) is received and the processing normally ends down to A2.
(If the processing ends abnormally in downloading, the data will be cleared.)
If the same program as the one in the memory is specified and the processing ends abnormally, the
program in the memory is deleted.
If the download is executed with exceeding the remaining steps or exceeding the stored program
numbers, sends ‘A4E00’ to end the processing.
If invalid M or T commands are sent, they will be M0 and T0. The block ‘M0T0’ is skipped.
(When only one of the pair is 0, ‘A4E00’ is returned.)
Origin return block is skipped. (When the program is uploaded, the block is added to output.)
If the program currently being executed is downloaded during operation, ‘A4E00’ is returned.
