Programming S7-300 analog input module

This is my first Siemens PLC programming.

I got a PLC 315-2DP with 1 DI, 1 DO and 1 AI modules. I have already configured the modules and then upload a simple program to test the I/O and get 4-20mA analog reading. Both digital input and output module are working good but I cannot get the reading from analog module.

I connected a 4-20mA simulator to terminal 2 & 5 of the analog module (331-KF02-0AB0) and deactivate channel 2 to 8 from Step 7 (version 11).

The starting address of my analog input is 288 which is assigned by Step 7. Under the monitoring mode, reading of channel 1 is always zero.

Is there any other setting I need to do? Attached please find the screens captured from my TIA software. Thanks

dont have the software here
but %Q4.2 refers to an Outut card BIT not an analogue word
PQW ??? been a while

Thanks iant,

Yes, %Q4.2 is the output bit for me to test the output module. It will be energized if analog reading %IW288 is zero.

Even I give 10mA to the analog module, value of IW288 is kept at 0.

Try piw288

Oh.. thanks JRW, you just reminded me to change the address from IW288 to IW288. It works now

Yep

Here ya go

Thats what happens wwhen you havent used the new TIA portal yet
sorry about that
