Siemens Building Technologies VISONIK DCS Functions and System Messages VVS18 CM2U8567E / 04.1999
Landis & Staefa Division Function TXIU 2-347
The following is defined in parameter TXI3:
–
the first text number of the associated TXI catalogue's
text value
set which relates to
the respective main parameters of point classes VIP, AI and AO (FMT=I-array)
or
–
the first text number of the associated TXI catalogue's
application-related
parameter long text
set for PAR1..PAR8 of point type PLT.
Depending on point type parameter TXU defines:
–
the text number of the TXU catalogue's entry containing the desired text for a related
physical (engineering) unit
(e.g. kWh).
or
–
the first text number of the TXU catalogue's block of entries containing the desired
text for
a point's states
(e.g. Off).
Parameter TXU2 defines:
–
for point type MX, the first text number in the TXU catalogue containing the desired
texts for the
point states
of parameter SX2 (e.g. Off)
or
–
for point type PLT, the first text number in the TXU catalogue containing the desired
texts for
physical (engineering) units
(e.g. kWh) associated with parameters PAR1..PAR8.
Parameter TXU3 defines, for point type MX, the first text number in the TXU catalogue
containing the desired texts for the
point states
of parameter SX3 (e.g. Off).
It is useful to have additional information printed out for alarm messages.
With parameter TXC, text can be selected from the Clear Text Register (TXCM,C).
This text, which will appear immediately after the respective point message, is output
according to the fault state change (Reason) as defined in parameter TXCR (Clear Text
Reason).
Parameter TXUaer is used to assign text to the possible states of parameters AERSTA
(see below for a short description of AERSTA).
Similarly, to output format FMT=U-array for main values of AI, AO, VP and MX points,
the individual states are displayed with text instead of numerical values.
Units text associated with the input and relay output contact states of an SEZ unit which
has been assigned to MONOGYR Room MGRn are defined in parameter TXUSEZ(n).
