A method includes automatically assigning, by at least one processor, an IEC address to an I/O binding variable for an RTU. This includes identifying a type of the I/O binding variable and identifying a size of the I/O binding variable based on the identified type. The size represents a number of memory locations to be used to store the I/O binding variable in at least one memory of the RTU. This also includes, 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.

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

A system includes a remote terminal unit (RTU) and a portable storage medium (PSM), such as a secure digital (SD) card. The RTU includes processing circuitry. The RTU includes a portable storage interface configured to physically connect to the PSM and electrically couple the PSM to the processing circuitry. The RTU includes on-chip memory. The processing circuitry is configured to determine that the PSM is coupled to the processing circuitry and access a specified folder of the PSM. The processing circuitry is configured to: in response to determining that the PSM stores function code in the specified folder, perform a specified function corresponding to the function code by executing the function code.
