Do i need to configure the hex parameters for each station? link for address ET200B /tf/WW/en/Posts/50617 What i read is that its not necessarily to configure the hex parameters since its automatically address but i have doubt of finding the right station. example ET 200B Station 1, Station 2, Station 3. correct and guide me thanks jeff Hello, From normal procedure's point of view, when you add a GSD(GSE) in data base of HW Config, it is just added to the catalog based on the description in the file(what type of slave it is).It is done in GSD file, all other basic information is also coming from that file such as number of I/O bytes to share with master, permissible baud rates and part of parameterization sections.Master receives all information and send request and receive data based on this information and then accep a slave on network. When you add slave from catalog to a master system, you can give a number to that.It should be same as configured number (PROFIBUS Address) via dip switches or internally saved in the slave.About the "HEX" parameters, you really do not need to change them. Hope that helps Hamid Hosseini

Just double click on a slave in the editor and check what you can change (e.g slave address,...) in the coming windows.For each slave, you have some tabs to check but refer the accompanying manuals for instruction in order to manipulate the parameters.

Normallly, we do not change that part for each slave.It is automatically generated by STEP 7.We should know that in case of using some special system functions such as SFC12 or SFC13.You can check that after for programming.Do not change the automatically assigned diagnostics addresses. step 7 online manual Diagnostic Address STEP7 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.

j3pd Posts: 30 Rating: (0)	Hi Expert, Sir hdhosseini, playerslight, ste39, Here is my another query, after configuring the master slave profibus communication, what is the best way to start with, should i used the diagnostics first? 1. Start Daignostics to verify the list of slave stations? how do i go about programming it? ________________________________________________ step 7 online manual wrote: Diagnostic Address STEP7 specifies a default address for diagnostics here.

Start Daignostics to verify the list of slave stations? how do i go about programming it? Hello again, First , you should read data from the slave.For that you can use the addresses in HW.Config plus using load/transfer or check and assign instructions. For diagnostics, there are several ways,Using OB86.But note there are some points to consider: I wanna know when DP Slave has a failure - OB86 Issue related to OB86 call after CPU startup in case of DP Slave [code] CALL SFC51 "RDSYSST" REQ :=#IN0 SZL_ID :=W#16#292 INDEX :=W#16#1 RET_VAL :=#TEMP3 BUSY :=#TEMP31 SZL_HEADER:=#TEMP4 DR :=#TEMP32 JBI M004 //failure of SFC51 processing BEU M004: NOP 0 //READ CONTENT OF DATA RECORD AN #TEMP32.TEMP34 //ZERO SHOWS FAULT = DB16.DBX 4.7 //1ST SLAVE FAILING AN #TEMP32.TEMP35 = DB16.DBX 5.0 //2ND SLAVE FAILING AN #TEMP32.TEMP36 = DB16.DBX 5.1 //3RD SLAVE FAILING AN #TEMP32.TEMP37 = DB16.DBX 5.2 //4TH SLAVE FAILING[/code] also see what "FB126" can provide as diagnostics information: Diagnostic package PNIODiag for diagnostic evaluation for PROFIBUS DP and PROFINET IO Best regards Hamid Hosseini
