These are outputs for the M, S, T or B command specified by the part program at its execu-

tion in the automatic operation mode.

If any of M, S, T and B command is found at the execu-

tion of the part program in the automatic operation mode, the control outputs it in a BCD or bin-

ary code according to the value that follows the detected command.

Then, after the elapse of the time set in parameter the M, S, T and B code reading outputs

are closed.

NOTE

With the

command, the 12-bit non-contact output or analog

output is provided, disabling the S code output and the S code
reading output.

2. Logic circuit processing M commands

The M code or MFA code outputs are not generated. These com-
mands are the M codes that are processed internally within the
control. Therefore, they cannot be used as the external M codes.

M decoded outputs (MOOR, MO1 R, M02R,

When the MOO, MO1,

or M30 command is executed, decoded

output MOOR, MO1 R, M02R, or M30R is generated accordingly in
addition to the M code and M code reading outputs.

The M decoded output opens when an automatic operation is

started or reset.

When the decoded output M command and move command are

issued for the same block, the M code output is generated at the
beginning of the block, but the decoded output is generated after
completion of move command execution.

A typical M decoded output time chart is presented in Fig. 20.24.
