If the Soft Switches have been determined to be invalid, the Soft Switch Entry utility is
entered upon power-up or restart. Once in this utility, you MUST correct the problem
either with the Logicmaster 90 Configurator or with a CHSOSW command before exit-
ing. Otherwise, the Soft Switch Entry utility will automatically be re-entered after a
power-up or restart.

CHTIME Command

(Not recommended if the PLC CPU is configured properly.)

The CHTIME command has the form:

CHTIME

where is an hour in the range 0-23

is an optional minute in the range 0-59 which defaults to 0
is an optional second in the range 0-59
which defaults to 0

This command sets the current system time to the value specified. If an invalid time is
entered, the current time is not changed. Leading zeros do not need to be entered when
entering the new time value. Time changes remain in effect until the Ethernet Interface
is powered-up or restarted. A typical CHTIME command is shown below:

= chtime 8:03

Time = 8:03:00.0
