APPENDIX B MODBUS PROTOCOLB.1 ACCESS TO F650 DATA
This document describes the procedure to read and write data in the F650 relay using ModBus/RTU protocol.
To prevent an existing integration from being affected by versions, a generic database has been created, compatible
between versions, with all possible items that a F650 may have, independently from its type or configuration. This
database describes completely each of these items. This descriptions includes the data type, length, memory position,
object version, etc. Moreover, the database will group the different objects by subgroups, such as status and settings
groups.
Each object has a unique memory position for the whole family. Only after reading the objects of a particular relay, it will be
possible to elaborate its map. This map will only be valid for that particular relay and memory version. From one version to
another the memory positions of existing objects remain fixed, and new objects are assigned new addresses, which again
remain the same for following versions.
It is possible to get the Memory Map using EnerVista 650 Setup software, menu:
