Replicating data from isolated network

A computer-implemented system, comprising:

• a local process information (PI) server of an isolated network;
• a corporate network different from the isolated network;
• one or more processors;
• and
• a non-transitory computer-readable storage medium coupled to the one or more processors and storing programming instructions for execution by the one or more processors, the programming instructions instructing the one or more processors to perform operations comprising:
• mapping a number of PI tags to data elements of the local PI server;
• at a first time, executing a first application at the isolated network to read and concatenate data on the isolated network corresponding to the tags and to replicate the data elements corresponding to temporary storage on the local PI server;
• generating, by the first application using the temporary storage, a replicated data package that is transmissible through a firewall of the corporate network;
• and
• at a second time after the first time, executing a second application at the corporate network to read data elements from the replicated data package corresponding to counterpart tags of the tags and to replicate the data elements according to instructions in the counterpart tags.

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• mapping a number of process information (PI) tags to data elements of a local PI server of an isolated network;
• at a first time, executing a first application at the isolated network to read and concatenate data on the isolated network corresponding to the tags and to replicate the data elements corresponding to temporary storage on the local PI server;
• generating, by the first application using the temporary storage, a replicated data package that is transmissible through a firewall of a corporate network different from the isolated network;
• and
• at a second time after the first time, executing a second application at the corporate network to read data elements from the replicated data package corresponding to counterpart tags of the tags and to replicate the data elements according to instructions in the counterpart tags.
