  • Page 13: Getting Started

    The EXDUL-518E / EXDUL-518S requires a supply voltage from +10V ... +30V DC at terminal 23 (Vcc) and terminal 24 (GND) to operate. The EXDUL-518PoE can be powered both via the terminals 23 (Vcc) und 24 (GND) as well as via the Ethernet cable using PoE. The power supply via PoE is only used if no power is available at the terminals.

    ® 4.3 Integrated Webpage of the EXDUL-518 Any web or internet browser such as Mozilla Firefox, Chrome, Edge, Safari etc. can access the EXDUL-518’s webpage via a TCP/IP connection. The wepbage allows to read connection information and change password pro- tected configuration data.

  • Page 15: Default Network Configuration

    ® 4.5 Default Network Configuration In the factory default setting, the EXDUL-518 is set to DHCP (Dynamic Host Configuration Protocol) to obtain a dynamic IP address. During pow- er-up, the EXDUL-518 requests an IP address from the network (LAN). A network with an enabled DHCP server automatically assigns an IP address to the module.

  • Page 16: Changing The Network Configuration

    ® 4.7 Changing the Network Configuration To change the factory default configuration settings, connect the EXDUL-518 to a local network using the RJ45 socket and the standard network cable supplied. A power supply (+10V ...+30V) is also required at terminal 23 (Vcc) and terminal 24 (GND) of the module.

  • Page 17: Configuration With Static Ip Address (Dhcp Disabled)

    ® Important note: The PC used and the EXDUL connected must be located on the same network to be able to communicate. For this, the computer‘s DHCP must be disabled and, for example, the first two number blocks (192.168) of the EXDUL IP address 192.168.1.83 (Subnet mask 255.255.0.0) must...

    ® Important note: We strongly recommend that you consult your network administrator before enabling DHCP. If you want to integrate several identical EXDUL-5xx series modules into a network, the preset host names are to be changed. Each host name within a network must be assigned to only one device or module.

  • Page 21: Lcd Display During Operation (Exdul-518E / 518Poe Only)

    ® 4.11 LCD Display during Operation (EXDUL-518E / 518PoE only) After booting, the display switches from information display to I/O status display or the UserLCD display, depending on the setting. When the I/O status is displayed, line 1 shows the current status of the inputs and line 2 shows the status of the outputs.

  • Page 22: Accessing The Exdul-518

    ® 5. Accessing the EXDUL-518 As already mentioned, access to the configuration settings and to the inputs and outputs of the EXDUL-518 is possible via the EXDUL-518 web page or via the TCP/IP sockets. For this, the IP Address, the host name or MAC address is required.

  • Page 23: Access Via Tcp/Ip Sockets

    ® 5.2 Access via TCP/IP Sockets A reliable connection between the PC and the EXDUL-518 is achieved by using the TCP protocol. The protocol automatically takes action in case of data loss. The module is addressed by a 4-byte IP address (IPv4) or the assigned host name and a port number 9760.

  • Page 25: Optocoupler Inputs

    ® 6. 11 Optocoupler Inputs The EXDUL-518 provides 11 input channels, each of which is optically isolated by optocouplers. The isolation voltage between the ground of the computer and the input is 500 volts. The voltage within the input channels is limited to 50 volts.

  • Page 26: Input Circuitry

    ® 6.2 Input Circuitry Optocoupler Protection Diode DIN_COM Fig. 6.2 Input circuit The optocoupler inputs are bidirectional. Normally the DIN_COM con- nector is connected to minus and a voltage is applied to the DINx con- nector. However, it is also possible to apply the positive voltage to the DIN_COM connector and the negative voltage to the DINx connector if this makes more sense in terms of circuitry.

  • Page 27: Optocoupler Outputs

    ® 7. 8 Optocoupler Outputs The EXDUL module provides 8 output channels, which are also optically isolated. The optocoupler output is amplified by a high power MOSFET, providing an output current of 1A per channel. A freewheeling diode is available for each channel for use in special situations.

  • Page 28: Freewheeling Diode

    ® 7.3 Freewheeling Diode If the optocoupler outputs are used to switch loads with low inductance and it is not possible to connect a freewhelling diode directly to the induc- tance, a freewheeling diode is provided in the module for each channel.

  • Page 29: Programming Of The Optocoupler Outputs

    ® 7.4 Programming of the Optocoupler Outputs For programming the optocoupler outputs, several access functions are available. This allows all channels to be controlled simultaneously or individually. If the current output state cannot be stored in the user application, it can be retrieved using a read command. Please note that the read switching state only corresponds to the primary state (on the processor side).

  • Page 30: Counters

    ® 8. Counters The module provides a self-contained, hardware-supported 32bit counter on each of the first 6 optocoupler inputs (DIN0 to DIN5). These can be activated individually, if required. They respond to each rising egde by incrementing the counter value. Any overflow is indicated by a retrievable flag.

  • Page 31: Programmable Logic

    ® 9. Programmable Logic In some applications it may be useful for the module to react autonomously to input signals or input changes. Without this option, the only way to detect a change is by regularly polling the inputs. This type of polling places a increased load on the network and on the computer.

  • Page 32: Logic Branch

    ® 9.1 Logic Branch Four different logic branches can be used in the module. Each branch has four inputs, one logic operation (AND, OR) and one output. Logic inputs and outputs can be assigned different functions. The logic gate can be event-controlled (e.g.

  • Page 35: Programmable Logic Timing

    ® Four message arrays are provided to allow the PC to distinguish which logic block is sending the message. The following table shows the 4 possible byte arrays. The first 4 bytes represent the command, in this case always 0x0E, and the length byte (always 2).

  • Page 36: Watchdog-Timer (Wdt)

    ® 10. Watchdog-Timer (WDT) The EXDUL module features a number of safety mechanisms to ensure a stable communication. However, if the communication is interrupted, e.g. due to routing problems, and it is not possible to re-establish the con- nection, you can use the module‘s integrated watchdog timer to solve the problem.

  • Page 37: Error Register

    ® 11. Error Register If any unplanned errors occur (e.g. a watchdog reset), they will be indicated in the two error registers. When an error occurs, the bit associated with the error is set. The error registers are maintained even after a reset or power off.

  • Page 40: Installing The Driver

    ® 13. Installing the Driver The Ethernet module EXDUL-518 does not require a driver. All that is required, is an existing network connection from a PC (network interface card with driver) or from a mobile device. Direct access to the module requires the TCP/IP libraries available in many high-level langu- ages such as C, C++, C#, Visual Basic or Java.

  • Page 41: Programming

    ® 14. Programming 14.1 Getting started You can program using the standard TCP/IP protocol and therefore via TCP/IP sockets, for which standard libraries are available in the most common programming languages. The use of Microsoft‘s .Net Frameworks allows easy and quick implementation. By using the standard protocol, the module can also be connected to a variety of other operating systems besides Windows, such as Ubuntu (Linux-based) or Android.
