In Pt 100 operation, only channels 0 to 7 are processed. Selection of heating
current monitoring, hot channel control and the special function is no longer
possible. The comparator can no longer be used (irrelevant in variant Ć3AB31).

Bit 7: This function applies for all controllers, for which self-tuning is possible (even if it
is not activated), when main control byte 1, bit 2 = ”1” and for all controllers where
a self-tuning function was run successfully, when main control byte 1, bit 2 = ”0”.
Bit 7 can be transferred to the IP with the FB 162 commands ”KS”, ”PA” or ”AE
message 15”:
If bit 7 = 1, bit 1 of the error bytes 0a to 12a is not set.
