Communication using Serial Commands
To enable the LS-7000 Series to transmit measured values or allow setting changes,
connect a peripheral device, such as a PC or PLC link unit to the LS-7000 Series.
Connecting to a PC/PLC Link Unit
The following section provides information on how to connect PCs or PLC link units to the
LS-7000 Series. Use the dedicated OP-35382 cable (with 9-pin D-sub connectors) or the
