Hello,

for first it can be better to know what exactly S7-300, what exactly ET200SP, modules. After describe more better your HWs then some one can give you maybe next help.

Hi ! For example, I have some problems with the config in picture attached :

impossible to have a 4-20mA signal on AQ card with a S7-300 whereas I have no problem from a S7-1500 with the same HW ET200 modules.

Could you help me ?

------------------------------------------------------------------------------------------
Split from IS IT POSSIBLE TO CONNECT AN ET200SP WITH AN S7-300?.

looks like you have not installed the needed HSP for the ET200SP IM.

looks like you have not installed the needed HSP for the ET200SP IM.

 My colleague who loaded program with Step v5.6 had the good HSP (GSD ?) but has the same issue with 4-20mA.

I tried with my only disposable v5.5 (HSP missing) and connected, when I took this screen capture.

So I think it's not the main cause of our problem.

 Is it possible to install a HSP on Step7 v5.5 for ET200SP IM155-6PN-BA v3.2 6AR00   ?

Where could I find it please ?

connect th system to internet

open hwconfig 

go option -> install HSP

let the system check which hsp abvailable and can be installed

as long you do not tell which problem you have exactly 🤷‍♂️

 No 4-20mA signal = 0mA on analog output A0 with any value in PAW tag, whereas with S7-1500 we have the signal from 4 to 20 mA with values attached.

it is also possible if you use VAT that for first set value to some MW and in code set simple MOVE this to exactly required PQW. If you have only code and no used VAT move to this PQW, it must work without problems like MOVE - 16#30 - PQW262 (example). You don't need set higher PI/PO ranges only if it is required in some situations. they are accessible via Proces image P from code without problems.

ChristophD

is the Adress of the AQ inside or outside the processimage?
on S7-1500 each adress is inside Processimage on S7-300  you must configure this

 How is it configurable, please ?

 My test was made by code with a MOVE (19000) in PAW272.

but i see now that the et200 is not connected to the PLC
you use a CP for communication with the et200 so you can not direct write the PAW

You must use the CP Commands to transfer the data to the ET200SP, please check the manual of the CP which commandy you need for that.

 It's seems to be a very good track to solution ;-)   Thanks !

If you have other info about this data transfer via CP343-1 to ET200 IM155 and AQ4, I will take.

How do you program communication blocks FC11 and FC12 for the PROFINET IO controller?

 Right ! I just have found the same ;-)

uuuuf so you don't have still the first important functionality? Ok...

Hope you did already that HSP instalation to have that IM rack completelly configured correctly.
