  • Page 15: Installation Of The Re-46 Canopen

    IP65 can only be achieved if all air connections are plugged either with a tube or a sealing plug. Connection cables must be plugged in also and should fulfill at least the same protection code (IP65 or higher). AIRTEC offers ready-to-use standard cables in different lengths for this purpose as accessories. ADVICE: When using cables of low quality or with reduced IP protection code the valve ter- minal might be damaged by penetration of dust and/or liquids.

    4.2 POWER cable Standard sensor cables with 5-pin circular female connector, M12 thread, A- coded  Straight or angled connectors can be used  Diameter of each conductor strand min. 0,25mm² (AWG 24)  Cables can be shielded or not shielded. A shield is not absolutely necessary but improves the EMC performance of the valve terminal.

  • Page 21 Connect the PROFINET inbound cable to the Port 1 connector 2 of the RE-46 and the fieldbus outbound cable to the Port 2 connector 3 . In star structures the Port 2 is not used. Tighten the fixing nuts of the cable only slightly with your fingers. Do not use any tools like a pipe wrench or combination pliers.

  • Page 22: Commissioning The Profinet Controller

    5.2 Commissioning the PROFINET Controller Below you will find the steps to the commissioning of the RE-46 in combination with the TwinCAT System Manager of BECKHOFF and EL xxxx PROFINET Con- troller. The PLC consists of a PROFINET Controller and is linked with an Industrial PC (IPC) via EtherCAT.
  • Page 23 Restart TwinCAT in configura- tion mode? Picture 3 (MessageBox) Confirm the restart with OK. Step 2: Scanning and inserting the PROFINET Controller I/O-Devices… Add device Search for devices… Picture 4 (Search for devices) Click with the right mouse button on IO-Devices\Search for devices for an auto- matic scan of your PROFINET Controller.
  • Page 24 1 New I/O-Device found Picture 6 (Selecting the LAN connection) Choose the LAN connection where your PROFINET Controller is connected and confirm with OK. Scanning for new boxes Picture 7 (MessageBox) Activate free run Picture 8 (MessageBox to start Free Run mode) Confirm the next two MessageBoxes with YES to attach your PROFINET Con- troller (in this case the EL6631) and to activate it in Free Run mode.
  • Page 25 I/O-Devices… Picture 9 (Found I/O-Devices) After a successful scan the new I/O-Device will be shown under I/O-Configura- tion. In this case: The EtherCAT coupler -> EK1100 The PROFINET IO Controller -> EL6631 The Termination Device -> EL9011 Add device Picture 10 (Add device) Click with the right mouse button on I/O-Devices and select Add device to at- tach the PROFINET Controller EL6631.

  • Page 26: Commissioning The Profinet-Device

    Device 1 (EL6631) Scanning for boxes… Picture 12 (Insert the RE46-PROFINET Device) After this step click with the right mouse button on Device1(EL6631)\Scan for boxes… to scan for the RE-46 PROFINET device. Make sure the RE-46 is con- nected and under power.
  • Page 27 The default device name is „re46-profinet“. Select the device in the list [1] and then click on Add Devices [2]. Picture 14 (Scan real config.) Confirm the next MessageBox with YES to finally attach der RE-46 PROFINET. Then close the scanning window by clicking the x in the right upper corner.

  • Page 29 Step 4: Creating a software task In order to exchange process data between the RE-46 PROFINET and your soft- ware application on the PLC/IPC, a software task has to be created on the Twin- CAT System Manger. Inside this task, some variables have to be created to handle the data.
  • Page 30 Picture 18 (Task settings) In Picture 18 you can see an example of the task settings. They can be modified by right-clicking on the task. HINT: This is only an example. The correct settings for your tasks might be different from these.
  • Page 31 Step 5: Creating the variables and shortcuts to the hardware HINTS: The number of the required variables depends on your application. These varia- bles shown here are just an example how to do it.

  • Page 32 Picture 20 (Configuratoin off variables) Enter the name for the next variable, i. e. OUT 09-16 [1]. Select the type of variable UINT8 (unsigned integer 8 bits) [2]. Confirm with OK [3]. Repeat these steps until you have created as many variables as required to con- trol all outputs.
  • Page 33 Picture 21 (Create shortcut) Now you have to create a shortcut between the variables in the task PROFINET and the physical outputs of the RE-46 PROFINET: Select the first API Slot #1, open the details by clicking on the node, then select the submodule (Subterm 1), then select Outputs and then 1 Byte Data Item [1].
  • Page 34 (solenoids), then confirm with OK. Repeat this step until all physical outputs are attached to variables. See also chapter 3.4 how to control the solenoids of the RE-46 PROFINET. Step 6: Activating the new configuration Activate configuration Picture 23 (Activating the configuration) In order to send the new hardware configuration to your PROFINET controller, you have to click on the button Activate Configuration.
  • Page 35 Picture 24 (Creating the new variables) Picture 25 (Acitvate the new configuration) Picture 26 (Restart the controller in run mode) Please confirm these 3 MessageBox with YES resp. OK. The controller will re-start then and should go into run mode.
  • Page 36 Step 7: Checking the PROFINET fieldbus connection After the re-start the controller should establish a PROFINET connection between the controller and the device. To check the correct function have a look at the LEDs on top of the bus system. After a few seconds you should see the following LEDs: LED Designation Color State...
