1 Introduction
This blog post describes only how to setup the DME4000 Laser measuring, to get the distance information from the sensor to the PLC. It does not describe the application specific settings that must be done to get the right values. It is used an EL6731, which is a Beckhoff Profibus Master, to connect the sensor to the PLC .
2 HW-Settings
In our setups normally there is only one DME4000 (one PB-Slave) connected to the EL6731 (PB-Master). Make sure that the terminators are available; otherwise the PB-Communication will not work
If there is only one connection at the EL6731, the Terminator must be set to On
If the DME-4000 is the last PB-Slave, it needs an Terminator
3 Laser Configuration
The DME4000 has 4HW-Buttons and one display to do the configuration:
The two arrow buttons are used to:
- Switch between sub-menus, that are on the same level in the menu tree
- Change a parameter if you selected an editable parameter
Esc Button is used to:
- Go one level up in the menu tree
- Abort setting a parameter
Set Button is used to:
- Go one level down in the menu tree
- Set an edited parameter
3.1 Edit Parameter
Set the parameters of the laser like described below.
1. Press “Set” to enter the menu
2. Navigate with the “Arrow” Buttons to the Parameter “Code”
3. There must be entered the Code 314, to enter the editing mode
4. Use the “Arrow” Buttons, to set the first number, to 3 and confirm with “Set”
5. Use the “Arrow” Buttons, to set the second number, to 1 and confirm with “Set”
6. Use the “Arrow” Buttons, to set the third number, to 4 and confirm with “Set” the complete code. Now it is possible to change the parameters.
7. Press again “Set” to enter the Menu and navigate to “Parameter” (3)
8. Press “Set”, to enter the Parameter Settings
9. Navigate to “Profibus” (3.1)
10. Press “Set”, to enter the Profibus Settings
11. Navigate to “Profile” (3.1.1)
12. Press “Set”, to enter the Profile Settings
13. Select “SICK” and confirm with “Set”
14. Navigate to “BusAddress” (3.1.2)
15. Press “Set”, to enter the “BusAddress” Settings
16. Depending on the Application, set the following Address.
17. Confirm the Address with “Set”
18. Press “Esc” to go one level back
19. Navigate to “Serial” (3.2)
20. Press “Set”, to enter the “Serial” Settings
21. Navigate to “BaudRate” (3.2.1)
22. Press “Set”, to enter the “BaudRate” Settings
23. Select 19.2kBd and press “Set” to confirm
24. Navigate to “Data” (3.2.2)
25. Press “Set”, to enter the “Data” Settings
26. Select 8,n,1 and press “Set” to confirm.
27. Press “Esc” to go one level back
28. Navigate to “Resolution” (3.5)
29. Press “Set”, to enter the “Resolution” Settings
30. Set Resolution to 0100um and press “Set” to confirm
31. Navigate to “Offset” (3.6)
32. Press “Set”, to enter the “Offset” Settings
33. Set Offset to 000000mm and press “Set” to confirm
34. Navigate to “Plausib” (3.7)
35. Press “Set”, to enter the “Plausib” Settings
36. Select 200ms and press “Set” to confirm
37. The Following submenus should be right by default:
a. MF1 (3.3)
b. MF2 (3.4)
38. Press “Esc” several times, until you get no more back in the menu
39. Repower the sensor
4 Check Functionality
To check the functionality, the Laser must be pointed on a reflector; otherwise it is not possible to measure a distance, and an error will be generated.
Additionally it must be sure, that there is no simulation active that will overwrite laser inputs.
