Hello friends
I have a PLC S7 300 with an OP7 and Festo Valves(Profibus).
In hardware diagnostic I got an error with slave DP.
It´s in spanish, sorry
According to this, error diagnostic should be in diagnostic address E 1022 but i don´t know where is this address.
If I try to program Input E 10.22 it doesn´t exist
I have simatic step 7 v5.4
Can you help me to find this?
[?]: Where is diagnostic address E 1022?

STEP 7 specifies a default address for diagnostics here. You can change this address.
The failure or return of a DP slave is reported to the master via this diagnostic address. The CPU then starts the OB86 "Rack/DP Slave Failure."
You can also use this address with SFC 13 DPNRM_DG to obtain the complete diagnostic information from the DP slave and include it in the CPU program.
For DPV1 slaves this address is assigned to the virtual slot 0.
Address for "Slot" 2
This address is visible in DPV1 mode only.
This address is used to report per diagnostics the operating state transitions of, for example, intelligent DP slaves.
Process interrupt requests can be transmitted to the intelligent DP slave via this address.
The address is assigned to the virtual slot 2.
Code: Select all
