Software Switches
Software Switches are used to output control signals from the CPU Unit to the
Serial Communications Board or Unit. The software switches are used for
loopback tests and to abort, release wait status, and control other functions
for protocol macros. For details on the software switch functions, refer to
Sec-
tion 5 Using Protocol Macros
and
Section 10 Loopback Test
.

Note
The One-shot Trace Switch and Continuous Trace Switch are used for the
Serial Communications Board/Unit only when executing traces from the CX-
Protocol in protocol macro mode. Do not manipulate these switches from a
ladder diagram.
Status Area
The Status Area is used for status information input from Serial Communica-
tions Board or Unit to the CPU Unit. The Status Area is where the Serial Com-
munications Board or Unit sets communications status, the transmission
control signal status, the transmission error status, and the protocol status.
