Connecting HMI (KTP700) to s7-1200 through profibus module CM1243-5

Dears,

I am trying to connect my HMI (KTP700 Basic DP, 6AV2 123-2GA03-0AX0) to my profibus module CM 1243-5 which is attached to plc s7-1200 plc (6es7 214-1ag40-0xb0) . 

I have created a very simple program (inverting a bit by pressing a button on the HMI). The problem is that every time I press the button I get this error:

"190011 - Tag-Tag_1: value could not be written on the PLC"

I think the problem is due to but connection between communication module and HMI but unfortunately i cannot find the solution . 

I am currently using TIA portal V13. 0, and I have already create profibus network in the Device & networks by connecting HMI (profibus address 2, 1.5MBs) with communication module (profibus address 1, 1,5Mbs)

Could you please help me with this problem 

Hello,

Can you check in properties of CPU:

Go to 'Protection & Security' -> Connection mechanisms

Is the 'Permit access ......'  selected?

What is the address you are using?

When you show Alarm View "view system alarms"  is the connection established or not?

Best regards,

Hello, 

Thank you for your reply. 

I went to "Properties>General>Protection" and there is selected " Full access (no protection)"

The address of HMI is 2 and for communication module is 1. 

When i am loading the HMI i am getting this error: 140001 Connection disconnected

Hello,

Which cable are you using?

Do you use Profibus connector? How did you connect cable?

Are you using Resistors?

Best regards,

Hello, 

I am actually using simulation on my PG. 

Thankyou

Hello,

Please have a look here:

Testing and simulation of HMI projects in conjunction with a SIMATIC PLC and PLCSIM

I think it is not possible to simulate CM1243-5.

Best regards,

You are absolutely right. This module it cannot be simulate. I try it in the real world and is ok. 

Thank you,
