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"
7.8 Recommended Cables Condition
7.6 Status Input Wiring
Status input appears across terminals S.I. (＋) and 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. (＋) and I/O. (－).
NOTE:
※1 Please select the cable size to be used with the number of signals.
※2 Depending on the number of output signals used, selection for the right cable material
must be made referring to the table on the next page.
