23.3 Memory layout
Cold-junction compensation can be implemented by using the KTY channels.
To do this, the parameters must be configured in such a way as to assign a
KTY channel to each measuring channel for compensation purposes.
Measuring ranges are configured using a single byte for the two channels in
each Xn connector. For example: The measuring range for 1+ and 2+ is con-
figured using object 0x50A0, where the high nibble is used to configure 1+
and the low nibble is used to configure 2+.
