The ERZ2000-DI records analogue and digital values, such as frequencies, re-
sistances, etc. Then these are assigned to physical variables, such as operating
volume flow or temperature. Further processing of these values takes place in the
ERZ2000-DI, where, for example, gas characteristics and standard volume flow
are calculated from these basic values. At the same time, a continuous check
guarantees that all necessary values are constantly available. An alarm or warning
message is triggered of adjustable limit values are exceeded or undercut.
The third task of the ERZ2000-DI is data storage and output, which can take place
in analogue and digital form. An alarm or a warning is also triggered if there is a
fault in the data recording.
1.4 Overview
The ERZ2000-DI, therefore, is an advancement of the ERZ2000 as a half 19"
slide-in module (half 19" width). Enhancements include a live browser (
chapter 2.3
Browser home page and coordinate system
) which enables permanent control of
the measurement data recording and reimbursement. A further enhancement is
the adjustment of the flow computer ERZ2000-DI and the parameterization of the
connected transmitters via a wizard on a PC. This wizard is not a separate PC pro-
gram, and is executed directly in the browser.
The ERZ2000-DI system has a configuration consisting of 2 function groups. The
first function group provides the quick measurement recording, all inputs and out-
puts, all interfaces and manual operation via the front panel or via the wizard. The
internal calculations and converter functions are processed by the second assem-
bly, the computing unit.
The working memory contains the variables, fields, buffers, etc. necessary for the
processing of the system software, as well as the (variable) device parameters of
all function assemblies. The device parameters are saved with a checksum that is
checked automatically each time the device is restarted.
The program memory contains the operating program of the device. A CRC check-
sum is calculated via the source and stored as a reference value. The correctness
of the checksum can be checked for the software ID in the coordinates of the
menu
IE Software ID with the specifications on the type plate (chapter "
2.7.3 De-
tails
" and chapter
"2.7.4 Functions
" – type plate).
