• Analog Output Data
For example, when analog input slaves 1, 13 and 20, analog output slaves 5 and 25, and analog I/O slaves 14 and 21 are
used, the analog I/O slave data will be allocated by configuration as shown below and maintained until the next configura-
tion is executed. Four channels (8 bytes) are always reserved for each slave.
