Mostly we r using F type and G type cable in instrumentation.
F type is individual and overall shielded.G type is over shielded.
Namely divided two type.Signal cable and control cable.signal cable carry 24vdc plus 4-20ma(AI/AO) . But control cable for DI/DO.24V DC,230AC,220 DC.Cable tray root also diff for diff signal.

When a timer is placed in RS Logix 5000 with preset value less than its scan time it is malfunctioning. i.e., if the preset is set to 30ms still the timer TT bit is counting till 150ms(its scan time). Any solution for the problem?
