Input/output (I/O) binding with automatic international electromechanical commission (IEC) address generation in remote terminal unit (RTU) configuration

An apparatus comprising:

• at least one processor configured to automatically assign an International Electromechanical Commission (IEC) address to an input/output (I/O) binding variable for a remote terminal unit (RTU);
• wherein the at least one processor is configured to:
• identify that the I/O binding variable does not have an assigned IEC address;
• identify a type of the I/O binding variable;
• identify a size of the I/O binding variable based on the identified type, the size representing a number of memory locations to be used to store the I/O binding variable in at least one memory of the RTU;
• and
• in response to determining that the at least one memory contains a free space to store the I/O binding variable based on the identified size, assign the IEC address identifying the free space to the I/O binding variable.

A non-transitory computer readable medium embodying computer readable program code that, when executed by at least one processor, causes the at least one processor to:

• identify that an input/output (I/O) binding variable for a remote terminal unit (RTU) does not have an assigned International Electromechanical Commission (IEC) address;
• and
• automatically assign an IEC address to the I/O binding variable by:
• identifying a type of the I/O binding variable;
• identifying a size of the I/O binding variable based on the identified type, the size representing a number of memory locations to be used to store the I/O binding variable in at least one memory of the RTU;
• and
• in response to determining that the at least one memory contains a free space to store the I/O binding variable based on the identified size, assigning the IEC address identifying the free space to the I/O binding variable.
