using RS logix to create two ladder diagram program or just draw the ladder diagram on paper by hand by following instructions below

9.4 Procedure 9.4.1 Exercise 1 -Subroutines This PLC logic will be used to monitor a butane sphere which has a safety pressure range of 85.0 to 175.0 psi. a) Convert three pressures from Psi (PSII, PSI2 and PS13) into Kpa (KPAI, KPA2 and KPA3) by jumping (3 times) to a subroutine called PsiTo Kpa. NOTE: The subroutine PsiToKpa MUST have ONLY 1 input value (PSI) and ONLY 1 output value (KPA). b) Calculate the average pressure in Kpa and store it in (AvePress) by jumping to a subroutine called Average. c) Check the value of (AvePress) to trigger an alarm by jumping to a subroutine called Alarm which is structured as follows: o GREEN light is ON if (95 psi
