note this driver is available for litmus edge version 3 11 0 and later review the following information for setting up and configuring the siemens s7commplus driver litmus edge compatible series compatibility parameter compatible items driver type ethernet validated devices/series s7 1200 v2 2 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, use plc software on your computer to configure your device for ethernet access 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 important the following settings are currently supported plc type only s7 1200 is currently supported firmware version v2 x and v3 x are currently supported parameter value type siemens driver siemens s7commplus network address the device address you defined during step 1 network port 102 plc type select s7 1200 firmware version select v2 x or v3 x read timeout (ms) 1000 retry count read retries 0 keep alive tcp keep alive 60 step 3 configure the list of registers when you add tags docid 8se7z3pmrfwl1nmzcwalx to the connected device, refer to the following tag parameters and available value types you can also search for pre defined device tags docid\ w1est a3midouizrksgvi for this device refer to the following additional resources organize device and tag data by using metadata docid 583p fbuozem6whgrdgkq tag formula variables docid\ ifbwcou90qtfodk hrysr 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 register name exactly as it is defined in the plc available value types note the following data types are available for litmus edge version 3 11 4 and later dt dtl wchar bool byte word dword lword usint uint udint ulint sint int dint lint real lreal s5time dt dtl time ltime tod ltod ldt date char wchar string wstring bool\[] byte\[] word\[] dword\[] lword\[] usint\[] uint\[] udint\[] ulint\[] sint\[] int\[] dint\[] lint\[] real\[] lreal\[] s5time\[] time\[] ltime\[] tod\[] ltod\[] ldt\[] date\[] 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)
