7.6 Status Input Wiring

Status input appears across terminals S.I. (
Status input setup procedure appears in 9.7.4 Status input.
※ Status input will be invalid if FOUNDATION Fieldbus, PROFIBUS PA is selected as communication
interface.

7.7 Communication Line Wiring (option)

For communications (option), use terminals I/O. (
CAUTION: 1. Bell202 HART communications protocol does not use these terminals. It
uses analog output 1 terminal.
2. Other communication interfaces require different handling. Please refer to
the supplementary communication manuals.
FOUNDATION Fieldbus communication: "ALTImass series communication
manual for FOUNDATION Fieldbus L-740FF"
PROFIBUS PA communication: "ALTImass series communication manual
for PROFIBUS PA L-740PB"
Modbus communication: "ALTImass series communication manual for
Modbus L-740CM"
