UPT-6012
Version 2
The limits of the tolerance band are adjustable up to a maximum of
±
99 K.
8.6.7
Control active (RA)
The UPT-6012 has successfully accepted the "START" request and entered control mode if the RA bit = 1.
8.6.8
Info active (IA)
This bit is reserved for future use and is not currently supported (it is always set to 0).
8.6.9
Standby active (SA)
This bit is active if the RS bit is set. It shows the PLC when the controller has accepted the RS_bit or the MP bit,
so that these bits can be reset again (handshake).
8.6.10 Measurement interruption (MU)
This bit is available as from firmware version 303.
This bit is active as long as the controller does not perform a temperature measurement during the regulation
phase (ST = 1). This can occur when the actual value is larger than the setpoint value (setpoint exceeded). This
can be used, for example, to evaluate whether measurement interruptions occur during the heating impulse. This
would then be an indication of excessive temperature, which can result in a bad sealing seam.
As soon as a measurement is performed again, the MU bit goes back to 0.
8.6.11 Actual value
8.6.12
All 16 bits of the first word must be interpreted as a signed number (twos complement notation). The
resolution is 1 °C. During the calibration procedure or if a fault occurs, the actual value is 0.
Start tem-
perature
The controller returns another 16-bit output word with the last start temperature. This is the temperature which was
measured just before the start command was executed (ST bit = 1). This value allows you to evaluate the cooling
process. It is only valid during the heating phase (ST bit = 1). Outside of this phase the value "-99 °C"appears, so
that it is possible to distinguish between valid and invalid values. The normal value range is between -20 °C and
500 °C.
