Interface. The Rosemount Model 268 may be used if available. The METT supports the Interface ASCII interface in a similar manner to the Varec Model 4110 HART Level Encoder (LE). That is, it answers to two different HART addresses. The first address is its address for normal operation. - Page 15 Element 10 Height HART Variable 1 Type Parameter to be returned as the first HART PV. Use F2/F3 to select. No configuration required if used with Varec's MFT. HART Variable 2 Type Same as above for the second HART PV.
