Commissioning Batch Controller RA33
38 Endress+Hauser
Protection using code
The entire local operation can be protected by a 4-digit code (default is 0000, i.e. no protection). If
the device is not operated for 600s, it is locked again automatically.
It is still possible to enter a value for the preset counter.
6.3.6 Logbooks
Changes to the setup are recorded in entries in the event logbook.
Event logbook
The event logbook stores events such as alarms, setup changes etc. with date and time. The memory
is sufficient for at least 1600 messages (however, depending on the text length, it is possible for
more messages to be stored). If the memory is full, the oldest messages are overwritten. The logbook
can be read out via the FDM data management software or on the device. To exit the logbook
quickly, press the +/- keys simultaneously.
6.3.7 Communication/fieldbuses
General notes
The device has (optional) fieldbus interfaces for reading out all process values. Values can be written
to the device only as part of configuration of the device (via FieldCare operating software and USB
or Ethernet interface) only. Process values such as flow cannot be transmitted to the device via the
bus interfaces.
Batch commands can be sent to the device via Modbus, for details, refer to "Modbus RTU".
Depending on the bus system, alarms or faults are displayed as part of data transmission (e.g. status
byte).
The process values are transmitted in the units that are also used for display on the device.
Only the counter readings of the most recently completed storage period (day, month, year, billing
date) can be read out of the memory.
For large counter readings, the places after the decimal point are truncated (e.g. 1234567.1234 É
1234567 or 234567.1234 É 234567.1).
The device can be read out via the following interfaces.
• Modbus RTU
• Ethernet/Modbus TCP
Modbus RTU/(TCP/IP)
The device can be connected to a Modbus system via RS485 or Ethernet interface. General settings
for the Ethernet connection are made in the following menu: Setup/Advanced setup /System/Eth-
ernet or Expert/System/Ethernet, → ä 40. Modbus communication is configured in Setup/
Advanced setup/System/Modbus or Expert/System/Modbus.
