Programming Example
M Code Reset Bits
These bits reset the M code output for each task.
If M code 0 to 499 is output in the program, that block will wait for an M code
reset and other commands will not be executed. The M Code Reset Bit can be
turned ON to clear the M code to 0 and turn OFF the M Strobe Flag.
Program execution will restart when the M Code Reset Bit is turned OFF.
Keep the M Code Reset Bit ON until the M Strobe Flag turns OFF.
If the M Code Reset BIt is already ON when a block is executed, that block’s M
code won’t be output.
