*** 26 TIMER ***
FUNCTION
This instruction will reset a timer or store the
elapsed time registered by the timer in an Input
Storage location. Instruction 26 can be used
with Program Control instructions to measure
the elapsed time between specific input
conditions. There is only one timer and it is
common to all tables (e.g., if the timer is reset in
Table 1 and later in Table 2, a subsequent
instruction in Table 1 to read the timer will store
the elapsed time since the timer was reset in
Table 2).
Elapsed time is tracked in 0.1 second
increments but displayed as an integer. For
example, a 20 second elapsed time is displayed
as "200". The time starts over after reaching a
maximum value of 65,536 - about 109 minutes.
The timer is also reset in response to certain
keyboard entries:
1. When tables are changed and compiled with
the *0 Mode, the timer is reset
automatically.
2. When tables are changed and then
compiled in the *B Mode, the timer is
automatically reset and Tables 1 and 2 are
disabled. Entering "*0" at this point enables
both tables and resets the timer.
3. Entering "*6" after changing the tables
compiles the programs, but does NOT reset
the timer.

*** 101 SDM-INT8 ***
The 8 channel Interval Timer (INT8) is a
measurement module which provides processed
timing information to the datalogger. Each of
the 8 input channels may be independently
configured to detect either rising or falling edges
of either high level or a low level signal. Each
channel may be independently programmed.
See the SDM-INT8 manual for detailed
instructions and examples. This instruction is
not in all PROM options.
