n SC module (sensor)
With this screen, you can check the module productions number and software revision of the
installed module.
n HOUSING ASSY
With this screen, you can check the module productions number, software revision, and HART
device revision of the housing assembly.
n Read logbook
The FLXA21 has two types of logbook per sensor to store history information on events, such as
changed settings and calibrations.
By selecting one of the logbooks that you wish to check, you can retrieve and check this
information. Storage of history information on each event in a logbook or which logbook to use for
storage can be set up on the Configure logbook screen. For details, see section 7.4.
History information on events are automatically stored on the preset conditions.
In addition to this storing, following three messages can be manually stored in the logbook;
"Sensor washed by hand", "Module replaced", "Sensor replaced"
To store these messages, press and select one of three messages from the Item on the
Memorandum screen. Its event date/time will be the time when a message is selected and
entered.
When a password for Commissioning is set on the passwords’ setup, pressing requires
entering the password. (Refer to the section 7.5.3.)
