8.2.2 Modbus virtual registers
In addition, the data of the log channels (1...32), which were read internally or exter-
nally in modbus master mode at the RS-485 interface, can be read via virtual data
registers using modbus TCP.
Three groups of data types with 32 channels each are available, whereby an automatic
assignment of the source data type to one of the three possible data types, depending
on the sign, takes place.
