  • Ethernet Based Managed I/O module
    JetI/O 6500's series is standalone Ethernet-based managed I/O modules.  The compact JetI/O 6500's series supports Din-Rail mount; hence, users can easily install the JetI/O in the control box with limited space.  JetI/O series also supports multiple channels of Analog Input/Output, Digital Input/Output, and the Temperature Measurement Connectors such as Thermal Couple Input and TRD Input.  Furthermore, the RJ-45 Ethernet port (console port) allows users to configure the settings, maintain the system, poll the information/status, monitor I/O status, program logic rules, and alarm events over the network.

  • HMI/SCADA Compatibility
    JetI/O 6500's series supports Modbus/TCP protocol, the most common protocol in network communication for industrial electronic devices over TCP/IP.   Modbus uses binary data encoding and TCP/IP error detection mechanism for measuring temperature and humidity and transferring the data between the connected devices.  JetI/O 6500 window utility also provides OPC Server for Modbus/TCP, so that the HMI/SCADA system can easily integrate to the JetI/O module. 

  • Easy Configuration & Maintenance
    JetI/O 6500's series provides several Windows R-based management utilities such as programming Example files for Device and I/O interfaces’ management.  The I/O configuration utility allows user to DISCOVER the JetI/O devices, configure the I/O interface’s setting, configure the alarm setting, set up SNMP Trap server, and monitor I/O Status.  In addition, The Device Finder Utility enables the users to view the settings, upgrade the firmware…etc, via the same utility.
    The built-in OPC Server for Modbus offers end-users the ease of polling the data of the JetI/O devices from the HMI/SCADA.  Users can also use the Example file of Modbus/TCP to program the I.O configuration as well as monitor each specific task of Jet/IO.  Overall, most of the I/O data/status does not change; the continuously periodical data polling sometimes may affect the network performance.  Hence, Korenix intelligent alarm notification allows the end-users to configure the pre-defined alarming rules.  In case of the pre-defined event, then the JetI/O will automatically update the changed data/status to the SNMP Trap manager.

    Why Indistrial PoE

    Industrial PoE switches are designed to operate in plant floor environments. Most commercial PoE switches have commercial temperature ratings
    (0-40C), and do not publish shock and vibration specs. Industrial PoE switches are rated for a minimum of (-20-60C) operation, and have excellent shock & vibration specs. Rather than commercial PoE usage, to deploy PoE apparatus in industrial environments has various kinds of challenges that should be concerned. Any carelessness may result in system failure, device damage or economical loss. A number of considerations are highlighted as below to help adopting PoE to industrial environments.
  • Reliability
    PSE Reliability: Acting as a power source, a PSE applies power to one or more PDs. A single PSE failure may lead to a number of PDs shut down. As a result, both the reliability of PSE itself and its input power then become two critical points to which must be given thought. Basically, the PSE should stay stable under its most unfavorable operating condition, such as temperature, humidity, vibration, shock, and so on. A stronger PSE may further equip with self protection mechanisms for undetected system failure. As to the power input, it can be enhanced by supplying through an UPS system or by other means to avoid from sudden disconnection.

    PD Reliability: The design of PD may be harden as described in PSE reliability to sustain harsh industrial conditions. However, a smart PSE may help to detect whether the PD is still alive. A detection of loss or failure event of PD can be reported to IT staffs by various management mechanisms, such as email, alarm, SNMP traps. The IT staffs then can take proper actions on the failure event. It is possible that a more advanced PSE which provides a management option of resetting the power connection could bring the PD back to alive more timely upon the failure is detected.

  • Diverse Output Voltage
    Just like various control systems, such as Modbus, ProfitNet, DeviceNet, used in different industrial applications, the power voltage required by each industrial application may vary.
    Take public transportation as example, the power supply system is usually DC 24V, which does not fall in the range, from 44VDC to 57VDC, defined in the IEEE802.3af standard. In some circumstances, an additional transformer may solve this problem. However, it may not meet the requirements for some particular reasons, such as spaces, maintenance, costs, and so on.
    Being able to feed a wider range of power voltage from the PSE would be a direct solution. This becomes another challenge for the PSE manufacturers to achieve the needs for diverse industrial applications.

  • Ultra Power Demand and Max Power Limitation
    Driven by the benefits and the evolution of the standard, more and more high power PoE solutions are coming to the market. WiMax base stations and PZT cameras are such kind of products already seen today.
    While the demand of high power is considered when arrange to go to PoE technology, it should be note that the amount of power drawn by the PD must not cause any damages to the PSE, the cable, or the PD itself. Power delivery generates heat and the cable bundling may exacerbate the problem. For safety concern, if either PSE or PD is not well designed to comply with the standard, the power delivery should be well controlled by some means to avoid over heating.

  • Wide-Ranged Operation Temperature
    The storage environment for control devices in industrial applications is often located at outdoors or in control rooms, where could be cold or hot, and humid. A well designed industrial grade PoE device should be able to operate reliably under harsh conditions.
    In particular, feeding power generates heat. The more power delivers, the higher the operation temperature of the PoE device raises. Surrounding with the ambient heat in the environment, the high temperature circumstances may get from bad to worse. The tolerance of high temperature and over-heat protection are two important points of industrial PoE.

  • Lurk of DC Disconnect
    There may be PD products designed to enter sleeping mode to save power if the device has been idle for a while. In power saving mode, the power consumption becomes low. However, according to DC disconnect process defined in the IEEE802.3af standard, there is a case that if the power draw goes lower than the DC disconnect minimum value, the PSE judges the PD removal and will stop delivering power. The PD is then turned off and cannot be woken up by its event triggers.
    Industrial applications must work stable and reliable. The problem is not limited to power saving. A PD designer should be ware of this lurk, and it is also recommend that a PSE provides some mechanisms to prevent unexpected DC disconnect.

  • Advanced Monitoring and Management
    In industrial environments, it may not be enough to power on a PoE device and let it go by itself. Advanced monitoring and management on each PD, PSE or even on each port of a PSE are important to IT staffs for many system maintenance requirements.
    For example, by polling the amount of real-time power delivering on each port of a PSE helps to monitor the current status and to have an idea of the trend of the PoE port. Abnormal conditions, such as power cut, over feeding or under supplying, can then be possibly observed in advance to prevent errors.
    Error detection can be also achieved by event-trigger approach. By setting a curtain circumstance of threshold, any irregular event exceeding the circumstance triggers a notification reported to IT staffs or results in a predefined action. Notifications can be in the form of alarm, email, SNMP trap or by other means. Accompanying with notifications, a predefined action can take place immediately for protecting or for recovering purposes before IT staff receives the notification and arrives for on-site service.
    Further more, detailed power control over a PoE system can also be used for security or power saving issues. Scheduling power control is one of the examples to save power and meet the economic resource utilization.
    Advanced monitoring and management which enhance the reliability, security and efficiency of a PoE system are essential parts for industrial environments.
