local Output5 = mc.mcSignalGetHandle(inst, mc.OSIG_OUTPUT5)
local Output12 = mc.mcSignalGetHandle(inst, mc.OSIG_OUTPUT12)

Hi,

Code: [Select]

if (mc.OSIG_OUTPUT24()==1)then
is  wrong. You cannot read a signal directly like that. You have to get the signal handle then read the state of the memory location
indentifed by that handle.

Code: [Select]

hsig=mc.mcSignalGetHandle(inst,mc.OSIG_OUTPUT24)
local output24state=mc.mcSignalGetState(hsig)
if output24state==1  then
........
