Configuring communications

Certain communication parameters are set from the Communication menu, including setting of the

instrument network address and activation of the multi-instrument feature (a.k.a. multidrop).

Figure 41 The Communication menu

The LWT instrument can monitor up to four values. These values are identified as primary (PV),

secondary (SV), tertiary (TV), and quaternary (QV).

The primary value (PV) is the only value directly linked to the 4 – 20 mA loop. It impacts other parameters

used by the instrument. For more information on setting the primary value, see "Setting up the primary

value (PV)" on page 43.

To set the remaining values, as necessary:

1 Select Communication > Dynamic Variables > Set [SV, TV or QV].

2 Press Edit.

3 Highlight one of the available values that you want to monitor (level, distance, ullage, amplitude,

electronics temperature, terminal voltage) and press OK.

NOTICE

As amplitude, electronics temperature and terminal voltage are not directly related to

level measurement, they are not available as a primary value.
