Diagnostic operation Start and stop Selected from "DI1 and 2, events 1 to 16, and standard bit
code" (set for each loop).

Graph display The health index graph bank displays the last 10 specific
R values (diagnostic parameters) for each control loop as
points and numbers on a graph.
Setting R value scale 0 to 10 (specifies the result of calculation × a power of 10)
Ideal data 0.0000 to 32000
Deviation low limit 0.0000 to 32000 (no low limit if 0.0000)
Deviation high limit 0.0000 to 32000 (no high limit if 0.0000)
SP high limit −32000 to +32000

Handling Precautions
• The bit (ON/OFF) data is also stored with a decimal point.
When ON: 1.000000
When OFF: 0.000000
• Some models of this device include a clock function and some do not.
• For models without a clock function, the date and time in the file attributes
and the date and time in the timestamp for the time sequence section indicate
the time that has elapsed after the device's power was turned on.
The power-on date and time is "2000/1/1 00:00:00" (YYYYMMDD HH:MM:SS).
Although data is stored in chronological sequence in a single file, when the
power is turned on again, the date and time will be reset, and further data will
be stored in a new file. For this reason, it is not possible to determine which
file is newer. However, if the date and time of this device are corrected, the
date and time will be up to date until the unit power is turned off, and the
corrected date and time will also be applied to the time stamp in the time
sequence section.
Determine which file is newer by the file name.
• For model numbers with a clock function, the date and time in the file
attributes and the date and time in the timestamp for the time sequence
section are based on the calendar timer in the CLOCK block of this device. The
calendar timer is backed up by a battery for use when the device power is shut
off. Determine which file is newer by the date and time in the file attributes
and the file name.
