YASNAC PCNC I/O Signal Function Manual Chapter 4: M, S, T, and B Functions
4.1 Input/Output Signals of M,S,T and B Codes
(1) M, S, T and B Code Output Signals and M, S, T and B Code Read Output Signals
Kinds and Addresses of M, S, T and B Code Output Signals & Read Output Signals
These are output signals for the M, S, T and B commands specified in a program.
If a M, S, T and B command is read during the execution of a part program in the automatic
mode, then CNC outputs the signals according to the numeric value specified with address
M, S, T or B.
Then, the M, S, T or B code read output signal is “closed” after the elapse of the time set for
a parameter.
IMPORTANT!
In the case of an S4 digit command, an S code signal and S code read signal are not output
since the output is a 12 bit no-contact output or analog output for a S4 digit command.
1.M commands for logic circuit processing (M90 to M99)
Neither M code nor MFA code is output. M codes are those for internal processing of the
CNC, and accordingly, they cannot be used as external M codes.
2.M decode output signals (M00R, M01R, M02R and M30R)
Among the M codes, if M00, M01, M02 or M30 is executed, the corresponding M decode
output signals (M00R(#35214); M01R(#35215); M02R(#35216); M30R( #35217) appear
in addition to the M code and M code read output signals. The M decode output signal is
“opened” at the start of automatic operation or when the CNC is reset.
If an M command with a decode output signal is specified together/along with an axis
movement command in the same block, the M decode output signal appears only after the
M code output MA0 to MA9 #35200 to #35211
S code output SD00 to SDO23 #36540 to #36567
Tcode output TO to T19 #35300 to #35323
B code output B0 to B15 #35330 to #35347
M code read output MF #35350
S code read output SF #36517
T code read output TF #35357
B code read output BF #35355
