Hi,

i have same problem. 2 F-PLC (1515TF and 1517F) connected with profinet. I have 2 projects so i used pdf, chapter 2.2 (Configuring IO controller and I-device cross-project)

https://support.industry.siemens.com/cs/document/109478798/configuration-and-application-of-the-profinet-i-device-function?dti=0&lc=en-WW

Ichecked HW identifer, put timeout to 500ms, check DP_DP_ID that match corectlly... Sending data from PLC (defined as IO-device) to PLC (defined as IO-Master) everything is working super.

Sending data from PLC (defined as IO-Master) to PLC (defined as IO-device) there is an error. Error happens when i trigger signal on true which i am trying to send. On SENDDP (PLC IO-master) i get status error 16#10 (byte) on RECVDP(PLC IO-device) i get status error 16#40.

I checked help, but cant find solution.I am using TIA 17 on both projects.

Thank you for your help

Split from SendDP OK RCVDP Error.

 hey you mentioned that everything works super,  Can you guide me how do you program SUBBO_XX and SUBI_XX  parameters ?

Hi,

they are the substitute values that are used in case of communication error.

I had to ask chatgpt, there is no trace on Siemens manuals

they are the substitute values that are used in case of communication error.

 This is diretly from Siemens manual:

Parameter | Declaration | Data type | Description

SUBBO_00 | Input | BOOL | Fail-safe value for receive data BOOL 00

 It's not a substitute value, it's the value the safety communication partner is configured to sent to your safety program. If there is a communication error, that value will be FALSE.
