Omron-NJ-Ethernet (Gen1)

review the following information for setting up and configuring the omron nj ethernet (gen1) driver litmus edge compatible series compatibility parameter compatible items driver type ethernet validated devices/series nj nx1p when configuring tags for this driver, you must enter the case sensitive register name exactly as it is defined in the plc see the free tags section below to learn more to set up and configure this device in litmus edge, you will need to do the following step 1 set up and configure the plc device step 2 set up the plc device in litmus edge devicehub step 3 configure the list of registers step 1 set up and configure the plc device if the device is configured for ethernet access, find its network parameters otherwise, follow the steps below to configure your device note down the following information and refer to it as needed device omron nj ethernet communication i/f ethernet refer to the following figure connect the device with a usb cable launch sysmac studio v1 20 1 0 software, select controller > communication setup , and then set up the ip address use a direct connection through usb > usb communication test step 2 set up the plc device in litmus edge devicehub configure the following parameters when you connect a device docid 3eyafppweuvmblcey17sq with this driver update default values to the specific setup of your device parameter value type omron driver omron nj ethernet nj301 1100 network address the device address you defined during step 1 port 44818 step 3 configure the list of registers when you add tags docid\ xgwokqbtpevii7or82ll0 to the connected device, refer to the following tag parameters and available value types refer to the following additional resources organize device and tag data by using metadata docid\ si z6r5dzyyuyhlwzq4zr tag formula variables docid\ luqaa9grfmp2tvcocgbt8 free tags this driver doesn't have a list of available register names in the devicehub add tag form to add tags, you must enter the case sensitive register name exactly as it is defined in the plc a connected status for the device won't display until a tag with a correct register name is created and a value is generated (not null/blank) available value types t arrays if you want to read a dint array, you need to write the element number of the array that you want to read in square brackets along with the tag name example if the array name is arraydint and you want to read the third element of the array, the format for the tag name in litmus edge is arraydint\[2] tag parameters name enter the case sensitive register name exactly as it is defined in the plc value type select a data type from the drop down list polling interval enter a value in seconds this determines how often the tag should poll the register for data tag name enter a name for the tag description (optional) enter a description for the tag tag formula enter a formula for the tag to process the generated data two variables are permitted value (current tag value) and timestamp (current tag unix time in milliseconds) the following math functions are available sin cos sqrt tan power power( x ) performs the operation 10^x log log( x ) is the natural logarithm (the logarithm is in base e ) exp exp( x ) performs the operation e^x only publish on change of value select the checkbox to customize nats messages to be published only when the value parameter changes from a previous value to a new one change of value only applies to boolean, numeric (such as int or float), and simple string data types it does not apply to complex types, such as json or array poll once topics will not be affected by change of value settings these topics will still only see a single message meta data metadata summarizes basic information about data this feature allows you to define key value pair data for the device output payload later on it can then be used to find, use, and reuse particular instances of data note if you use special characters in meta data key names, the special characters are replaced with underscore characters in the payload this can cause two key names to be combined into one for example, configuring the key names a b and a&\&b will cause only one key name to be created (a b)
