8.6.9 Information active (IA)
This bit is intended for later use and is currently not supported (always 0).
8.6.10 Standby active (SA)
This bit is active when the RS bit is set. With it, the controller can detect when the controller has accepted the
RS bit or the MP bit and the RS bit or MP bit will then be deleted again (“handshake” procedure).
8.6.11 Measurement interruption (MU)
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.
8.6.12 Actual value
When the compact protocol is used, the actual value always represents a positive number. The prefix bit (VZ) then
displays whether the actual value is positive or negative. In case of alarm, the actual value contains the error
number.
In the
expanded and complete protocols, the entire 16 bits of the first word are evaluated as a prefixed number
(two’s complement depiction). In case of an alarm or during calibration, the actual value is 0. The error number is
on separate bits.
8.6.13 Start temperature
If the optional “Temperatures” submodule should be projected, the controller supplies an additional 16 bit output
word with the last start temperature. This is the temperature measured directly before execution of the start com-
mand (ST bit = 1). This measurement value can be used to evaluate the cooling. The value is valid only during the
heating phase (ST bit = 1). Outside of this phase, the value “-99 °C” is output, with which it can be differentiated
whether or not the value is valid. The value range lies between -20 °C and 500 °C.
8.6.14 Error numbers
If an alarm is present (AL bit = 1), the error number allows determination of the exact cause of the error. The
parameter “Error number format” determines whether two- or three-digit error numbers are output. With the two-
digit error numbers, some alarms are combined into groups, while the cause of the error can be determined more
precisely with three-digit error numbers.
The error number is displayed in the compact protocol in place of the actual value in bit 0…3 (error number format
= 4 bit) or in bit 0…9 (error number format = 10 bit).
In the expanded and complete protocols, the error number appears in the second word at bit position 8…11 (error
number format = 4 bit), or at bit position 6…15 (error number format = 10 bit) (
 section 8.19 "Error messages"
on page 49).
Besides the error numbers, the PROFIBUS diagnosis is also used to transmit error messages to the PROFIBUS
master. The error messages for the corresponding error numbers are already stored in the GSD file and so auto-
matically appear in plain text in the PROFIBUS master when the device diagnosis of the UPT-6006 is queried. The
language in which the error messages appear depends on the selected GSD file.
10-bit error numbers are always transmitted over the PROFIBUS diagnosis independently of the set-
ting of the “Error number format” parameter (
 section 8.7.9 "Error number format" on page 34).
