Analog module showing overflow value 7FFF

hello

in my project s7-417(step7)

There are a number of four-wire and two-wire  Which contains “FIT TT PIT “are Sometime in monitoring displays the amount of overflow(7FFF)

,And when we disconnect one of the THEY from the terminal of the input module, their values are displayed

The AI module is not fault as i checked it on othe CPU ,project it is working fine.

I soon code modules sending

Here are a number card installed

Which contains “fit tt pit “are

For example, in a module analog some of the channels two-wire and some four-wire configuration have been

For example, overflow that happens if we open wire negative an consumption transmitter of channel the other channels to the amount of normal returns and are OK 

what this happens?

PLEASE HELP FOR THIS PROBLEM

 Dear PLC2011,

please send us the information requested by Daniel in the previous post. and if possible the part of the program where they are configured.

hi PLC2011,

have you had a look in the manual, how the module should be wired and configured?

SIMATIC S7-300 S7-300 Module data  chapter 6.6

Is this a new system, or an already working system?

regards,

hi

the order code modules are :331-7kf02-0ab0

Can I be in a module with8 INPUTs:

I configured this way: connected4 SENSORto the module  4-wire current transducer

AND2 SENSORCONECTED to this module 2-wire current transducer

Is there a problem with this configuration, which is used in combination.

for example:CH0 ,CH1\CH2,CH3 is 2DMU

AND CH4,CH5\CH6,CH7 is 4DMU

I think that's the problem
Because their winring is different from that of Siemens method

Hi dear, are you have any solution for this problem?

Thanks for your help.
