2.1.1 Downloading NC Data
From AVK3, when the host computer sends C0 command to AVK3, the AVK3 goes into receiving mode, and
as a result, can read the data (C0 command is used) sent to it.
Data details

Input range Remarks
1 Program control No. 15
‘0’ to ‘9’
‘A’ to ‘Z’
Special character
Can be omitted.
It is necessary to include the first
character.
When the machine receives the C0 command, the A0 command is returned as acknowledgment.
The host computer receives this A0 command, and using D command (Data transfer command) sends
leading block (one block) of NC data (N0001 or N1) to the AVK3.

=REMARKS=
If exceeding the max. digit number, the data of the max. digits from the head becomes valid.
S & R data continues M90X at the beginning. If it appears on the way, it will cause an error.
If ‘∗’ character is found in one message, it becomes EOP.
If a character cannot be judged, the following numeric values will also be ignored.
If a space appears, the characters thereafter will be ignored excluding the circuit Nos.

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.
