This object sets the low threshold of the normal operating temperature range for each
thermocouple’s input field value ($6100.) Any FV value below this limit flags a low warning in the
corresponding thermocouple’s status byte ($6150), as well as setting an EMCY code in the pre-
defined error field ($1003). The data in sub-indexes 1 to 4 is interpreted with a fixed resolution of
0.1°C/bit.
