APPENDIX F: SPEEDSYS300 ODS301 MODBUS REGISTER DEFINITIONS
F.1.3 Current values
Table F-3 describes the SpeedSys300 ODS301 Modbus registers related to
current value parameters, that is, the Modbus registers to be used to obtain the current
(“live”) values from a module.
NOTE: The Modbus registers in this data block are read only.
