The paper is focused on the problem of increase of the dependability and adaptability of IIoT systems in critical infrastructure. The problem is considered in the context of implementing hybrid forms of solid-state memory in embedded components of IIoT systems, adapted to high dynamics of information exchange. Restraining factors for efficient operation with variable memory in such systems have been analyzed. The optimality of split systems such as eMMC/FRAM, SD-card/FRAM, or SPIFlash/FRAM has been justified. A method for remote access to the non-volatile memory of IIoT devices with hybrid architecture in such split systems has been proposed. A model of interaction between the access agent and file repositories has been developed, and prototypes of file system utilities for working with hybrid hardware modifications of solid-state drives have been obtained. A solution has been proposed for developing software interface extensions intended for personnel interaction with components of the IIoT system based on the software development process model for embedded systems' HMI extensions. An optimized GUI library implementation for HMI based on WiFi modules, taking into account the specific implementation of EmSYS and IIoT systems, has been developed.
