The HART menu in chapter 7.4 shows the configuration of the online menu, which is needed for the opera-
tion with HART communicator. Select ´Device Setup´ to call up the desired item as follows:
There are two choices to select the desired menu item:
1. Use the ↓ or ↑ key to select the desired item, and then press the → key.
2. Press the number key displayed for the desired item.
To return to the previous display, press the ← key
Entering, setting and sending data:
The data, which is input with the keys is set in the HART-communicator by pressing
ENTEr. Then, by
pressing SENd, the data is sent to RCCT_F3. Note that the data is not sent to ROTAMASS if SENd is not
pressed. All the data set with the HART-communicator is held in memory unless power is turned off, so all
data can be send to RCCT_F3 in one lot.
IMPORTANT
Parameter setting on the display with the infrared keys is prohibited during HART communication.
IMPORTANT
Do not turn power off just after HART-Communicator settings (sending) have been made. If ROTAMASS
is turned off less than 30 seconds after parameters have been set, the set data will not be stored and the
data returns to previous settings.
6.4 Unique functions of HArT Communicator
Check on communication error:
When over run error, framing error, parity error or buffer overflow error is detected, the data including the
information of errors is returned, and the error message is indicated on HHT.
Time recording:
Online → Device setup → Detailed setup → Device information → Date
Month and day can be set in a number of 2 figures, Year in 4 figures.
Multi-drop communication:
Field devices in multi-drop mode refer to the connection of several field devices on a
communication single line. Up to 15 field devices can be connected when set in the multi-drop mode.
To activate multi-drop communication, the field device address must be changed to a number from 1 to 15.
This change deactivates the 4 to 20 mA output and turns it to 4 mA.
