Notes for handling each part of the unit
[Connecting extension cables]
Always be sure that the extension cable connectors are securely engaged.
[Memory cassette handling]
When detaching a memory cassette, raise the wire handle and slowly pull the handle attached
to the
cassette. Always be sure the
power to the unit is OFF before attaching and detaching memory
cassettes.
[Special function unit labels]
Special function units and blocks such as FX-1GM PGU, analog
I/O
units, and high-speed counter
units which are accessed by using FROM/TO instructions are numbered from 0 to 7 beginning with
the one closest to the main unit of a programmable controller.
Use the unit number labels supplied with the unit by sticking them to the front panel of each special
function unit.
See page 134 for applicable versions of programmable controllers.
