12 Handling of M, S, T, B Functions

12.6 Precautions

12.6 Precautions
(1) M code data and MF output timing (Also applies to S, T, B signal)
When the built-in PLC is used, the M code data n and MFn are output simultaneously to the user PLC. When outputting
the M code data and MF to the machine with the user PLC of built-in PLC, insert an appropriate time timer on the MF side.
(2) The finish signals (FIN1, FIN2) are commonly used for the M, S, T, B functions, so turn them ON under the conditions
where all function operations have been finished.
(3) When the "M function lock" signal (AFL) is turned ON, the M, S, T, B functions (including M commands in fixed cycle)
issued during automatic operation (memory, MDI or tape) and manual numerical command, will not be executed. In other
words, the code signal, MF, SF, TF and BF signals will not be output (updated). However, when the M code independent
output (M00, M01, M02, M30) is commanded, the "M code independent output", "M code data" and MF will be output as
usual.
(4) The 2nd miscellaneous (B) function can be selected from address A, B or C using the setup parameters. The "B function"
refers to when address "B" is selected.
