hi Licarry,

only for getting the analoge signal see page 3:

Analog Output (Absolute Pressure) 1 to 9 VDC, 1 VDC/decade, 100W maximum output impedance 

Therefore you need an analoge input module for voltage 0-10V. The analoge signal comes from Pin5(+) and Pin6(-) of the Plug.

If you want to communicate whit this module and get the value over RS232 or RS485 you need a CPU or a CP to connect. This communication goes over Pin1(-) and Pin2(+)

hope this helps,

regards,

 Hi mopS04

Thanks for your previous solution.

I need one more help

In Siemens step7

1)May i know how to setup hardware for 10 analog input and 10 analog output  in CPU 315 DP 2

if its not possible means which CPU setup is convenient for 10 analog input/output

Analog Communication

2) How to program for reading the pressure from quantity-10 gauges. All the gauges should have one generic function block which is called up for 10 times - please help to create it.

May i know for this one we do it using Scale or some other option.
