I work via Kepware.
5 digit addressing vs. 6 digit addressing.
In my case O50 (Unitronics) => 005051 (KepServer). Its work.
For example: MI18(Unitronics) =>400019 (KepServer)
ML4(Unitronics) =>405109 (KepServer) (must calculate addres according to type).
Very bad that is not table transformation addresses (SI,SB,O,I,T etc to Modbus addresses via KepServer)
Thanks.
