64 ACF5000 FTIR ANALYZER SYSTEM | OI/ACF5000-EN REV. A
Operating the analyzer system
The analyzer system is operated via the following:
The display and control unit in the door of the analyzer cabinet (local HMI)
A remote HMI
A web page
Local HMI operation
All functions required for normal operation of the analyzer system can be
accessed via the display and control unit in the door of the analyzer cabinet.
Remote HMI operation
All functions that are accessible via local HMI can also be operated from a
computer that is connected to the analyzer system via Ethernet and installed
on the "AO-HMI Remote control interface" software tool. Detailed infor-
mation on the remote control can be found in the technical information
AO-HMI.
Note: When describing display and operation in this operating instruction,
"HMI" is used to refer to both local HMI and remote HMI.
Preference of an HMI
The analyzer system can only be operated from one single HMI.
The hierarchy of the passwords regulates what HMI has or is given prefer-
ence during operation (see also following table). As a rule, the HMI with the
password for level n+1 receives preference before an HMI with the password
for level n. In deviation from this, the local HMI already receives with the
password for level n preference before a remote HMI also with the password
for level n.
1st user: 2nd user:
Remote HMI receives… Local HMI receives…
Remote HMI level n Preference with level n+1 Preference with level n
Local HMI level n Preference with level n+1 —
NOTICE
If a 2nd user with an HMI is given preference over another HMI, all entries not
confirmed with ENTER of the 1st user are lost and ongoing procedures (e.g.
an adjustment) are canceled.
