6 Basic configuration
Once the magnetic flowmeter is installed and power has been supplied, the
transmitter must be configured through the basic setup. These parameters
can be configured through either an LOI or a Modbus host. Configuration
settings are saved in nonvolatile memory within the transmitter. Descriptions
of more advanced functions are included in the product reference manual.
6.1 Local operator interface (LOI)
To activate the optional LOI, press the DOWN arrow. Use the UP, DOWN,
LEFT(E), and RIGHT arrows to navigate the menu structure. A complete map
of the LOI menu structure is shown in the product reference manual.
The display can be locked to prevent unintentional configuration changes.
The display lock can be activated by holding the UP arrow for three seconds
and then following the on-screen instructions.
When the display lock is activated, a lock symbol will appear in the lower
right hand corner of the display. To deactivate the display lock, hold the UP
arrow for three seconds and follow the on-screen instructions. Once
deactivated, the lock symbol will no longer appear in the lower right hand
corner of the display.
6.2 Modbus configuration
Each register is identified by its address (or starting address). Depending on
the PLC that will be used to communicate with the transmitter, you may need
to subract 1 from the address or starting address of the register. Refer to your
PLC documentation to know if this applies to you.
