6.9 Recommended Cables condition
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"
6.8 Communication Line Wiring (option)
For communications (option), use terminals I/O. (
＋
) and I/O. (
－
).
NOTE:
※
Please select the cable size to be used with the number of signals.
※
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.
