In a __very large systems__, there are sometimes hundreds of devices (usually identical), with hundreds of even thousands of registers in each of them. If all these parameters were declared in a WebHMI register list, this would heavily load the system, increase scan time, increase processing time etc. | In a __very large systems__, there are sometimes hundreds of devices (usually identical), with hundreds of even thousands of registers in each of them.
