Answer / ashish khatana

TAKE TWO TAPINGS, ONE AT 5CM (HP SIDE)ONE AT 75 CM (LP
SIDE). NOW CONNECT THE DPT AS PER HP AND LP CONNECTION AND
IN Tx. ALSO DEFINED THE LSV AND USV IN Tx. IT WILL GIVE U 4
MA AT 5 CM AND 20MA AT 75 CM OF THE TANK LEVEL.

NOW THE SAME THING U CAN DO FOR THE COMP. MOISTURE LEVEL.
TO OPERATE SOV U HAVE TO USE THE ANALOG SIGNAL COMING FROM
DPT AND WITH USE OF THIS U HAVE TO GENERATE A DO COMMAND
(24V). THIS COMMAND WILL DIRECTLY GO TO SOV(24 V) WHEN
LEVEL IS HIGH.

SUPPOSE DPT TAG IS (PI01)
SET PI01.HH AT 75 CM.. AND USE THIS SIGNAL TO GENERATE THE
DO FOR SOV USING A SWITCH LOGIC IN DCS
