i am working with et200s in my company but i have an issue here.all the output devices connected to it is not running what could be the problem
Mind you, I don't know enough to actually help you here. But, I would start by checking all the indicator lights - are any of them red as in is something faulted?
Cardosocea mentioned 'stuff you have defined' . . . Is the ET200S defined inside the Step 7 program?
I also get the impression you don't really understand what you have here? From what I see, the ET200S is an input output rack. There must be an actual PLC somewhere . . . You also mentioned an IM151-7 . . . Which appears to be :
>>> IM 151-7 CPU Interface Module >>>
>>I Uploaded the program to my laptop so all configuration was uploaded two see attached
Reading and writing the I&M data of the IM 151-7 CPU with STEP 7
Reading:
● In STEP 7 the I&M data are displayed under "Module state – IM 151-7 CPU" ("General"
and "Identification" tabs) and via "Available nodes" (Detail view) (see Online Help for
STEP 7 ).
● In the user program, the I&M data can be read via SFC 51. Specify the required SSL
sublist number and the index in the input parameters of the SFC 51 (see table below).
Writing:
You will always need STEP 7 HW Config to write the M data of modules.
For example, you can enter the following data during configuration:
● Name of the automation system (device name)
The device name is assigned when you create the station in SIMATIC Manager. In this
case a "SIMATIC 300(1)" station is created by default. This name can be changed at any
time.
● You can enter the following data in STEP 7 HW Config on the "General" tab under "CPU
Properties":
– Name of the module

This is a link to some information I found on the IM151-7 module . . .
What is the CPU? how does the CPU communicate with these I/O modules?
MadPoet.
This IM-151-7 has a CPU in it. It can be used as a dumb IO module or as a PLC (which could possibly take over some function in case of comm fault).
Where is that Profibus cable going to? Is it going to another PLC? Or another IO rack?
Do you have the original project and the correct TIA Portal version?
How are you turning on the output?? Are you modifying the program? Are you forcing on the hardware configuration?
Did you manage to read the diagnostic information on the CPU?
