what is input and output cards of plc needs to be hot
swappable mean
Answer / carl_ellis
To 'swap' is to 'exchange'.
'Hot' means electrically live and powered.
The term "hot swappable" means that an I/O card can be
replaced while the PLC/PAC/controller rack/chassis is
powered and running.
The assumption is that the controller will recognize
or 'see' the replacement card and do whatever
initialization is required to bring the I/O card back on-
line.
An I/O card that is not 'hot-swappable' requires a cold
start, power-up, initialization sequence for the controller
to recognize the card.

In split range control, we will control 2 outputs with time interval. Eg :(with 4-20 ma signal, for 4-12 ma we are operating one control instrument like valve & for 12-20ma we are operating other control instrumet (other valve). If we get a signal of 15ma to first instrument (Valve 1), what will happened to the first valve, and if we get signal above 20 ma to 2 valve what will happened ?
