9 E) Enable everything: - Enable the Profibus card of DeltaV - Enable the slave Version A4 For internal use only! Page 9

10 LED diodes for PB master: - Power: always ON, green - Error: OFF - Port 1: always ON, yellow F) Download everything: Result: If everything is correct, the question marks disappear and the BF LED of the CPX-FB13 stops flashing: Version A4 For internal use only! Page 10

11 1.2. CPX-FB13 online diagnostics The following DIL switch must be set for the CPX-FB13: Step 1: Start diagnostics. Version A4 For internal use only! Page 11

12 Step 2: Rescan the port (P01): Step 3: Open CPX-FB13 Profibus diagnostics: Version A4 For internal use only! Page 12

13 See, for example: Text diagnostics: Or more detailed diagnostics: Version A4 For internal use only! Page 13

14 1.3. How to use CPX-FB13 diagnostics in a DeltaV Software project The CPX-FB13 has the following diagnostics options: The two diagnostics options marked in red are closely linked to the device definition entry. In other words, if you want to evaluate the diagnostics in the user program, you must opt for one of the following DeltaV entries: Version A4 For internal use only! Page 14

15 DP-Slave Status bits [DP-V0] After choosing the DP-Slave [Status] entry, you must create the corresponding variable (status byte): Version A4 For internal use only! Page 15

16 Once this has been created, it must be downloaded -> Download Physical Network. The variable can then be found here: Version A4 For internal use only! Page 16

17 You can then evaluate this variable at any time in the main program or view it in diagnostic mode. Example: See undervoltage message in Primary Parameter Value : Version A4 For internal use only! Page 17

18 18d = Version A4 For internal use only! Page 18

19 DP-Slave Status Interface [DPV1] For additional options, an 8DI/DO is inserted in the configuration and texts are used for greater clarity: The two-byte I/O (Signal001) is configured as in Point A). Version A4 For internal use only! Page 19

20 Sample configuration for the two-byte input: Version A4 For internal use only! Page 20

21 In diagnostic mode, you still have the same status byte information as with A without a program). Example: Short circuit on 8DI/DO: 9216 = Version A4 For internal use only! Page 21

22 To use the I/O interfaces correctly, you also need a program. To do this, you must do the following: a) Insert a new module. Version A4 For internal use only! Page 22

23 b) Open Control Studio. c) Assign variables. To do this, simply drag the blocks (of Special Items) onto the screen and assign the correct variable by clicking the right mouse button The input parameter EINGABE has the following configuration: Version A4 For internal use only! Page 23

24 The input parameter STI_IN has the following configuration: The output parameter STI_OUT has the following configuration: Version A4 For internal use only! Page 24

25 d) Using the I/O interface correctly After the program download, you can describe the STI_OUT variable in online mode. This is crucial in order to use the I/O interface correctly Version A4 For internal use only! Page 25

26 The following example can be found on pages 5-17 of the CPX_SYS manual: This means that in the event of an error, for example a wire break on the 8DI/DO, function no is used to determine which module has this error. Version A4 For internal use only! Page 26

27 EXAMPLE: 1. Write the value in EINGABE. Why 37255?: Function no would be: > (control bit: 32768) (34705) is not equal to 37255, but as we have to observe the byte swap in this case: ( ) --> ( ) 2. Generate a short circuit on 8DI/DO. 3. Look at the result in STI_IN: Version A4 For internal use only! Page 27

28 The result is In reality this is (after byte swap) This means Diagnostic message from module 3 (CPX-8DI/DO) available See CPX.SYS example again Note: The I/O interface gives you read access to the entire diagnostics and all parameters of the CPX terminal. More detailed information can be found in the CPX.SYS manual (see Section & Appendix B) or in the module manuals P.BE-CPX-EA-DE / P.BE-CPX-AX-DE You can avoid the byte swap by removing the following check mark: Version A4 For internal use only!

29 2. CPV & Emerson DeltaV 2.1. Configuring CPV-DIO2 Note: In this case, the existing project with CPX is extended to include a CPV Profibus slave: Step 1: Start DeltaV Explorer -> Similar to HW Config from Siemens. Version A4 For internal use only! Page 29

30 Step 2: Install the device definition file. If everything works correctly, the library structure will then look as follows: Version A4 For internal use only! Page 30

31 Note: The library is not updated automatically if you want to use CPV-DIO1 & CPV-DIO2 simultaneously. The reason: DeltaV Explorer ignores the Config files with the Vendor_Name, which contain a blank after the uppercase Character. In this case, simply change the device definition entry Festo CPV-DIO2, for example. A): Open the device definition file with the Editor. Version A4 For internal use only! Page 31

32 B): Change the vendor name and save the device definition file under a different name. C) Install the updated device definition file in the Emerson library. Result: CPV-DI01 and CPV-DI02 are available. Step 3: Insert the device definition CPV-DIO2. Version A4 For internal use only! Page 32

33 Step 4: Set the correct address (see DIL settings) and enable the device: Version A4 For internal use only! Page 33

34 Step 5: Select the correct device definition entry. The Basis entry is the default entry without CP extension. Step 6: Create a signal. Version A4 For internal use only! Page 34

35 Step 7: Download everything. Version A4 For internal use only! Page 35

36 Tip 1: Create a test block in Control Studio and link the test block with the signal tag 16DA. You can now test the switching function of the valves quickly and easily Version A4 For internal use only! Page 36

37 Tip 2: If you wish to use the CP string, simply add the corresponding CP modules to the Basis entry 16DA. Important: First save the configuration on the CPV cap -> Press the Teach button. Example: CPV-DI02 + CP-A04 + CP-E08 The configuration would look as follows: The functionality can simply be tested with Control Studio using test blocks. Version A4 For internal use only! Page 37

38 Note: Be careful with the byte swap for the CPV-DI01 and CPV-DI02 cap. When you want to connect the first valve (viewed from left to right), you must enter the value 256 for bit 1. Version A4 For internal use only! Page 38

39 The byte swap is prevented by removing the following check mark: If you now write 1, the following happens: Version A4 For internal use only! Page 39

40 2.2. Configuring CPV-DIO1 CPV-DI01 is configured in much the same way as CPV-DI02. Please note the information on pages 31 & 32. Step 1: Insert the device definition CPV-DIO1. Step 2: Set the correct address (see DIL settings) and enable the device: Version A4 For internal use only! Page 40

41 Step 3: Select the correct device definition entry. The On-Board entry is the default entry without CP extension. Our configuration looks as follows: CPV-DI01 + CPV_CPI + CP-E08 Version A4 For internal use only! Page 41

42 Download everything: If everything has been done correctly, the network looks as follows and the bus LED on the black cap does not flash -> Only Power is on. Important: With the black cap you must set the CP extension via DIL switch. With the white cap you must use the Teach button. The byte swap is prevented with the black cap in the same way as it is with the white cap. Simply remove the following check mark: Version A4 For internal use only! Page 42

43 2.3. CPV Top Hat diagnostics DeltaV supports Profibus standard diagnostics. The extended diagnostics function is not supported. For this reason, evaluation of the diagnostics via Control Studio is not possible. Only a small amount of information on the CPV caps can be viewed via standard DeltaV diagnostics. Only with DeltaV Version 11 or higher with a Profibus Series 2 Plus card does it appear to be possible to integrate extended diagnostics into a control strategy (Control Studio).
