AB CompactLogix Ethernet Advanced

note this driver is available for manufacturing connect edge version 3 5 2 and later review the following information for setting up and configuring the ab compactlogix ethernet advanced driver overview this driver can be used for better performance multiple tags that belong to the same polling cycle can be read in a single request/response notes the maximum length custom string that the driver can read as a string is 480 characters this driver provides faster performance over other compatible drivers if you prefer stability over speed, you can use ab compactlogix ethernet freetag docid\ b7jz q 8macy071pbdvq the driver implements two modes symbolic and compactlogix symbolic mode in symbolic mode, the driver supports both compactlogix and controllogix connections this mode makes tag grouping more efficient compared to the standard driver by trying to combine as many tags as possible but not exceeding the maximum transmission unit (mtu) size for both requests and responses compared to compactlogix mode, it performs better when dealing with plc changes compactlogix mode in compactlogix mode, only compactlogix connections are possible the driver uses numeric handles instead of symbolic names usually this allows the reading of more tags per single request compared to symbolic mode, especially if symbolic names are quite long compared to symbolic mode, it performs better overall without taking into account plc changes plc changes the driver does not detect plc program changes structure templates are read once when a connection is established if the plc program is changed, you need to restart the connection manufacturing connect edge compatible series compatibility parameter compatible items driver type ethernet validated devices/series compactlogix controllogix 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 manufacturing connect 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 manufacturing connect 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 the device for ethernet access step 2 set up the plc device in manufacturing connect edge devicehub configure the following parameters when you connect a device docid\ rfvijdxz7dbad8mwbisma with this driver update default values to the specific setup of your device parameter value type allen bradley driver ab compactlogix ethernet advanced network address the device address you defined in step 1 network port 44818 access mode select symbolic or compactlogix slot number 0 step 3 configure the list of registers when you add tags docid\ ioanzd2awqnkuppgee3eh to the connected device, refer to the following tag parameters and available value types you can also search for pre defined device tags docid\ mocoh 5sebdz22wwbjsuf for this device refer to the following additional resources organize device and tag data by using metadata docid\ f b720nivllber44rfyhn tag formula variables docid\ pwd 7p kzjxkt pyawaow 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 available value types bool byte sint int dint real dword lint lreal string 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)
