Fault On Red PLC is in STOP/Faulted mode: a fatal fault has occurred. Refer to Troubleshooting FAQs for more details. No fatal faults detected.
  • Page 9 Note: • LAN2 will not be operational unless it is configured from the programmer with a valid IP address. • Care must be taken when assigning IP Addresses and subnet masks to each LAN so that an overlapping IP subnet is not created. Intermittent or no Ethernet communication may result if an overlapping IP subnet is created and the two interfaces are NOT connected (cabled) to the same physical network.
  • Page 10 Figure 3: Typical Multi-Tier LAN Application (Star/Bus topology) Typical Multilevel Network Application Whenever CPE115 is configured for MRP only, Ethernet Port2 & Port3 of LAN2 may be used to form a ring. Ethernet Port4 of LAN2 may still be used either to connect to the programmer, to a simplex PROFINET device or to any other supported Ethernet protocols.

  • Page 12: Usb Port

    USB Port CPE115 has one USB Port located on top of the front panel. It is currently disabled. As a result, CPE115 does not support Remote Device Storage Device (RDSD). Serial Ports CPE115 provides both RS-232 and RS-485 ports. RS-485 port supports two modes of operation: 2-Wire and 4-Wire.
  • Page 13: Hardware Installation

    As the consignee, it is your responsibility to register a claim with the carrier for damage incurred during shipment. Emerson will fully cooperate with you, however, should such action be necessary.
  • Page 14: Installation & Mounting

    Installation & Mounting As shipped, the CPE115 is intended for mounting on a DIN rail. An optional panel- mount adaptor is also available (part number: ICMFAACC001-AA). If panel- mounting is required, replace the DIN-rail adaptor with the panel-mount adaptor using the screws supplied with that adaptor. Both adaptors attach to the rear of the CPE115 chassis using four M3 screws.
  • Page 15 Instructions for Mounting the CPE115 on a DIN Rail The CPE115 snaps easily onto the DIN rail, as shown in Figure 6. No additional tools are required. Incline the unit so that the upper hooks of the DIN rail adaptor engage with the upper edge of the DIN rail.
  • Page 16 Instructions for Mounting the CPE115 on a Panel Attach the panel mount plate to the rear side of CPE115 using the four M3 screws supplied with the adapter. Fasten the tabs of panel mount adapter in the appropriate location of panel with the four screws.
  • Page 17: Grounding

    CPE115 to a suitable ground stud in the enclosure panel, or to the DIN Rail. The DIN rail onto which this product will be mounted must be grounded as per the instructions provided in the PACSystems RSTi-EP User’s Manual, GFK-2958.
  • Page 18: Module Start-Up

    Module Start-up Power-Up Time The CPE115 requires at a minimum 35 to 40 seconds to complete power-up. When power is applied, all the Ethernet Port LEDs blink once. When power up is complete, the OK LED turns on and remains steady whereas the RUN LED indicates the current run mode.
  • Page 19 • Ethernet cable for connecting the PME programmer computer to the CPE115. • Very small slotted screwdriver (2 mm blade jeweler’s size) for securing wires to the connector. Basic Installation Steps: For start-up and configuration of the CPE115, complete the following steps: Be sure to disconnect the power to CPE115.
  • Page 20: Programming The Cpe115

    Programming the CPE115 To configure the CPE115, connect the computer running the PME programming software to an Ethernet port of LAN1 using the default IP address 192.168.0.100. PME 9.5 SIM 1 or later is required. Configuration will either start out using the RSTi-EP CPE115 template when creating a new project or will convert an existing project to the CPE115 using the Family Conversion feature in PME.

    Figure 11: Configuring as an Embedded PROFINET Controller OPC UA Server Configuration To configure CPE115 as an OPC UA server, refer to Chapter 10 of the PACSystems RX3i and RSTi-EP TCP/IP Ethernet Communications User’s Manual, GFK-2224. Serial Port Configuration CPE115 provides two serial ports - COM1(RS-232) and COM2(RS-485). They can each be configured for one of the supported modes using PAC Machine Edition Tool (Version 9.50 &...
  • Page 22 Modbus RTU Configuration The CPE115 may be configured as a Modbus RTU Slave device using either or both serial ports (RS-232 or RS-485): (Refer to Figure 5). The Serial Port Setup COMMREQ function can be used to activate a Modbus RTU protocol over a serial port. To configure the Serial Port COMMREQ Data Block on CPE115, refer to section 6.1.6 of the PACSystems RX3i and RSTi-EP CPU Reference Manual, GFK-2222.
  • Page 23: Performance With Typical Configuration

    Performance with Typical Configuration The below diagram shows the system configuration with four CPE115 connected to one PROFINET I/O node each and interfaced to one RX3i CPE400 with four EGD exchanges each. Out of 4 CPE115 units two of them are connected to Modbus RTU Master having RS-232 and RS-485 Serial connections.
  • Page 24 For more details on the configuration of the above set-up and the typical loopback time across all the PROFINET nodes, please refer to GFK-3086. It also documents other examples of system configurations and the performance limitations of this product Product Limitations Timed interrupt blocks are not supported.
  • Page 25: Replacement Of Internal Supercapacitor

    Replacement of Internal Supercapacitor The supercapacitor board associated with the CPE115 is EPSACC001. Use this part number when ordering replacements. Do not attempt to use any other replacement part for this procedure. CAUTION • Perform all electrical replacements in a suitably clean and dry environment. Clean away all surface contaminants before opening the electrical circuit enclosure.
  • Page 26 Power off the unit and wait for 5 minutes to allow the internal supercapacitors to discharge completely. Clean the exterior surfaces of the unit before bringing it into a suitably clean lab environment. Detach the side panel cover by removing the (M3) screws with a Phillip’s head screwdriver.
  • Page 27 Figure 15: Supercapacitor Carrier Figure 16: Supercapacitor Board Board Assembly Using the reverse procedure, install the new supercapacitor card onto its carrier board. Check that the mounting holes are aligned properly before tightening both the M2.5 screws. Recommended torque is 3 in-lb (0.3 Nm). Reconnect the mating connectors.

    Troubleshooting FAQs Why does my controller not power on after I apply power? (None of the front panel LEDs are illuminated.) The incorrect power supply may be used. Verify that the correct power supply is connected, and that the Figure 17: power connector is fully seated.
  • Page 29 How can I restore the default IP address or perform a factory reset on my controller? To reset the IP Address to its default (192.168.0.100) or to Figure 18: perform a factory reset, complete the following: Run/Stop User needs to power down the controller. Pushbutton Press and hold the membrane Run/Stop pushbutton (Figure 17) during power up.
  • Page 30 How can I recover the controller from the Stop/Faulted state? A Stop/Faulted state cannot persist through a power cycle. To recover the controller, there are two methods: Power cycle the controller Perform a CLEAR operation from the PME software. When should I replace the internal supercapacitor? Whenever a Failed Battery Signal fault is logged in the controller’s fault table, replace the internal supercapacitor by following the instructions in the section entitled Replacement of Internal Supercapacitor.
