Let me clarify my question. I know from looking at the ini file that signal 1142 is associated with Spindel_Fwd. Assuming that is true, can I replace this:

Read_Signal(1142)

with this:
Read_Signal(mc.MC_SPINDLE_FWD)

Or do I simply reference the signal state using "mc.MC_SPINDLE_FWD" and drop the Read_Signal portion?

it would be mc.OSIG_SPINDLE_FWD.
