	1) What is PLC (Programmable Logic Controller) validation? And 2)Why PLC AI (Analogue Input) signals comes in low BITs input. i.e. 8 X 12 BIT and PLC AO (Analogue Output) signals goes in high BITs output. i.e. 4 X 16 BIT

	PLC validation is an assessment made by someone other than the individual that programmed it that the thing does exactly what is required in the Functional Design Specification. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	Thanx for your precious reply. And my apologies for late reply too. I've just wanted to confirm about the "assessment done by any individual". Is that means it is other than the PLC manufacturer, that a person or individual who selects the required hardware i.e. PLC cards & developes the ladder program for the functioning? Pl. reply Thanx in advance.
