The assignments of inputs and outputs are shown in menu MA Input / output function
key.
Inputs
The assignment of inputs to "physical values" takes place in menus "A Measure-
ments", "B Components", etc. The units of these measured variables are also defined
in these menus in order to ensure correct transfer of the values. Normally, the manu-
facturer and type of transmitter of the physical variable should also be defined here,
particularly for custody-transfer applications, for which there are certified and ap-
proved transmitters. In
chapters 5 Transmitters, 6 Flow meters
and
7 Parameter of
the
gas
, the explicit assignment is covered and explained in detail.
The free inputs can be assigned functions and the measurement values can be writ-
ten to archives (e.g. to the free archive
chapter 2.5.6 Archive
). There if a selection of
functions for each input, as is the case with the standard inputs for pressure or tem-
perature. Limit ranges and significances can also be defined. There is an input field
available for each measurement value for assignment of a name. Special measure-
ments are found in menu
O Miscellaneous
(see
chapter 5.4 Special
measurements
).
The 8 contact inputs can be assigned to messages, etc. The message can be a no-
tice, warning or alarm and assigned arbitrary text. Entries are also made in the DSfG
log book. The 8 contact inputs can also be optionally assigned as 6 special counters
or 8 binary inputs.
Note
The special counters are designed for slow metering processes and their max-
imum frequency is limited to 5 Hz.
The 8 binary inputs can be assigned free text and a meaning (notice, warning or
alarm). The corresponding entries are made in the log book.
Up to 4 routes / billing modes can be selected per switch / contact. Assignment of the
switches / contacts to the terminals takes place in menu
EC Billing mode
, sub-item
EC04 Bill. mode selection
(see
chapter 6.2.1 EC Billing mode
). The following
choices are available:
Billing mode 1/2/3/4
1 contact switches in 2 directions
2 contacts switch in 2 directions
2 contacts switch in 4 directions
4 contacts switch in 4 directions
