    Hello,

    Is it possible to manage string data coming directly from the devices in version 6 ?
    If yes, how can I use them in channel in order to have them showed as device data.

    Thank you

    Hello,

    It is possible in case a driver supports strings. Currently, the following drivers can provide string data: OPC UA and OPC Classic.
    What communication protocol and driver do you plan to use?

    Hello Mikhail,

    Thank you for your reply.
    I’m using “MQTT Client” driver

    Is it possible to do that with this driver ? Is a customization needed ? If yes, what would be the conditions ?
    This is very important and urgent for me…

    Could you provide examples of the strings?
    Are they predefined constants? For example, “Status A”, “Status B”…

    No. They are not predefined.

    Following are examples of strings :

    Examples 1:
    F. F. F./ F. F. F.

    Examples 2:
    In Sw cl. Out Sw cl. M-By Sw op. By Sw op.

    Examples 3 ( the longest possible one ):
    Rectifier fault. Inverter fault. Auxiliary power fault. Fan fault. Input Thyristor failed. Invert Thyristor failed. bypass Thyristor failed. Fuse broken. DC BUS volt. abnormal. Initializtion fault. Battery Thyristor failed. Charger fault. Parallel fault. Parallel on invalid. DC component over limit. Mains Site Wiring Fault. Input Neutral line missing. Bypass Site Wiring Fault. Battery Reverse. No Battery. Feedback protection. Battery Fault. Battery temperature over. Overload. Parallel Overload. Battery under voltage. Battery over voltage. Battery low pre-warning. Mains freq. abnormal. Mains volt. abnormal. Bypass unable to trace. Bypass Not Available. Bypass over current. LBS Not SYNC. System Not Synchronized. Ext. Fire Alarm. Ext. Smog Alarm. Mains Abnormal. Battery under voltage. Bypass Output. UPS fault. Invert Output. UPS Power Integration Fault alarm. Over temperature. Transfer Times-out. ShutDown/Batt Low. UPS in Bypass/Overload. UPS in shutdown/Overload. Inv invalid/Overload. Inv Off/Overload. Inv Off/PowerOff. Bypass Supply Power. Rectifier Over Current. ByPass Switch Opened. Manu-Bypass Switch Opened.

    For the example 3 you should create separate tags like
    – Rectifier fault
    – Inverter fault

    They should not be strings.

    The feature of working with string tags may be added in the future version of the driver. I’ve added it to the wish list.

    You can read strings from OPC UA and OPC Classic. If you need to read a string, configure OPC driver and create channels using the Administrator tools. Channels for strings would be created by the wizard.
