  • Page 5: User Features

    User Features The PACSystems™ RSTi-EP EPSCPE100 (or CPE100), is an enhanced performance standalone 1GHz programmable controller equipped with 1 MB of user memory and four Ethernet ports. It is designed to run real-time, deterministic control applications and supports distributed I/O. LAN 1 is a dedicated high-speed Ethernet port.
  • Page 6 8 Clients total are permitted and may be a combination of SRTP or Modbus/TCP. Up to 8 simultaneous Class 1 Ethernet Global Data (EGD) exchanges. When used in combination for optimal performance, use must not exceed 4 Channels for Server (Modbus/SRTP) and 4 Channels for client (Modbus/SRTP), 8 PROFINET nodes and 8 EGD data exchanges.

  • Page 7: Membrane Run/Stop Pushbutton

    Membrane Run/Stop Pushbutton Figure 1: Start/Stop Pushbutton The Membrane Run/Stop push button is located at the bottom right of the front panel (see Figure 1). Pressing it briefly, will change the state of CPU from the state it is in to the next state. It acts as a toggle switch, as shown in the following state diagram: The Run/Stop switch is enabled by default;...
  • Page 8 LED LED State Operating State (at Power-Up) Blinking; All This LED indicates the status of PLC during powering other LEDs off up. It starts blinking 6 seconds after applying power to the PLC and remains in this state for up to 15 seconds. After this all LEDs turn off and will remain in this state until PLC is ready.

  • Page 9: Ethernet Ports

    Ethernet Ports CPE100 provides two independent Fast Ethernet LANs. LAN1 has only one port and is dedicated to the embedded Ethernet controller. LAN2 is comprised of 3 switched ports, each configurable either as a second embedded Ethernet controller or as an embedded PROFINET controller.

  • Page 10: Typical Network Application

    Typical Network Application A typical application will take advantage of the two independent LANs. The dedicated LAN1 port will be used for communications with plant-level or supervisory layers. The switched LAN 2 will be used to communicate with devices over PROFINET within the manufacturing cell or process.

  • Page 11: Multi-Tier Networks

    Multi-Tier Networks Whenever CPE100 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 CPE100 has one USB Port located on top of the front panel, but currently it is disabled for security reasons. Serial Ports CPE100 supports both the RS-232 and RS-485 ports. RS-485 port supports only two modes of operations 2-Wire and 4-Wire. These ports are located on the underside of the controller (Figure 5).
  • Page 13 RS-232 RS-485 Signals Signals Pins 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 CPE100, refer to section 6.1.6 of the document PACSystems RX3i and RSTi-EP CPU Reference Manual, GFK-2222.

    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 15: Instructions For Mounting The Cpe100 On A Din Rail

    Instructions for Mounting the CPE100 on a DIN Rail The CPE100 snaps easily onto the DIN rail, as shown in Figure 3. 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 Cpe100 On A Panel

    Instructions for Mounting the CPE100 on a Panel Attach the panel mount plate to the rear side of CPE100 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

    Grounding Proper grounding of the CPE100 is essential. Use the ground terminal located on the underside, as shown in Figure 8. Use a 16-22 AWG braided wire with lugs to connect the ground terminal of the CPE100 to a suitable ground stud in the enclosure panel, or to the DIN Rail.

  • Page 18: Module Start-Up

    Module Start-up Power-Up Time The CPE100 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: Basic Installation Steps

    • Ethernet cable for connecting the PME programmer computer to the CPE100. • Very small slotted screwdriver (2 mm jeweler’s size) for securing wires to the connector shown in Figure 10. Basic Installation Steps: For start-up and configuration of the CPE100, complete the following steps: Be sure to disconnect the power to CPE100.

  • Page 20: Programming The Cpe100

    Programming the CPE100 To configure the CPE100, 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 CPE100 template when creating a new project or will convert an existing project to the CPE100 using the Family Conversion feature in PME.

  • Page 21: Opc Ua Server Configuration

    Figure 11: Configuring as an Embedded PROFINET Controller OPC UA Server Configuration To configure CPE100 as OPC UA server, refer to chapter 10 of the document PAC Systems RX3i and RSTi-EP TCP/IP Ethernet Communications User Manual, GFK-2224. Serial Port Configuration CPE100 provides two serial ports - COM1(RS-232) and COM2(RS-485).

  • Page 22: Modbus Rtu Configuration

    Modbus RTU Configuration The CPE100 can be configured as a Modbus RTU Slave device using either or both the serial ports (RS-232 and RS-485) located on the underside of the controller. The Serial Port Setup COMMREQ function can be used to activate a Modbus RTU protocol over a serial port.

  • Page 23: Performance With Typical Configuration

    Performance with Typical Configuration The below diagram shows the system configuration with four CPE100 connected to one PROFINET I/O node each and interfaced to one RX3i CPE400 with four EGD exchanges each. Out of 4 CPE100 units two of them are connected to Modbus RTU Master having RS-232 and RS-485 Serial connections.

  • Page 24: Product Limitations

    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 CPE100 is EPSACC001. Use this part number when ordering replacements. Do not attempt to use any other replacement part for this procedure. WARNING • Perform all electrical replacements in a suitably clean and dry environment. Clean away all surface contaminants before opening the electrical circuit enclosure.
  • Page 26 Detach the side panel cover (Figure 13) by removing the (M3) screws with a Phillip’s head screwdriver. Figure 13: Controller Side Panel Figure 14: Supercapacitor Board Location Using a screwdriver, remove the two M2.5 screws and detach the supercapacitor card from the carrier board (Figure 15). Disconnect the mating connectors.
  • Page 27 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. Verify the assembly has been restored as shown in Figure 14. 10.
