Ethernet i/o card scanner

An electronic device for configuring an ethernet I/O card in a process control environment, including:

• a processor;
• a communication interface coupled to the processor;
• and
• a memory coupled to the processor storing instructions that, when executed by the processor, cause the processor to:
• (i) analyze a decoder file, for a field device configured to be coupled via an ethernet link to an ethernet I/O card (EIOC) in a process control system, mapping one or more field device variables to one or more message positions;
• (ii) generate a dataset including one or more device signal tags (DSTs), each representing a process variable corresponding to a different one of the one or more field device variables, mapped to the one or more message positions;
• (iii) upload, via the communication interface, the dataset to a configuration database for the process control system to include the dataset so that, when the process control system is configured according to the configuration database, the one or more DSTs correspond to the one or more message positions such that the EIOC is configured to:
• (a) implement a controller output handling function in which the EIOC is configured to:
• (1) receive, from a process controller, a controller output message including a controller output value for a first DST, and (2) respond by assigning the controller output value to a first message position mapped, according to the dataset, to the first DST, such that the controller output value is transmitted from the EIOC to the field device at the first message position for a field device input message transmitted to the field device;
• or
• (b) implement a controller input handling function in which the EIOC is configured to:
• (1) receive, from the field device, a field device output message including a controller input value at a second message position that is mapped, according to the dataset, to a second DST, and (2) respond by assigning the controller input value to the second DST, such that the input value is transmitted from the EIOC to the process controller as a value for the second DST as part of a controller input message.
