p3 Handling of abnormal data in a channel for
TLOG computation
ERROR: Handled as computation error.
SKIP:
Abnormal data are skipped
(ignored) and computations are
executed.
p4 Handling of overflow data in a channel for
TLOG computation
ERROR: Handled as computation error.
SKIP:
Abnormal data are skipped
(ignored) and computations are
executed.
LIMIT: If linear scaling has been set, its
upper- and lower-limit values
are computed. If it has not been
set, the upper- and lower-limit
values in the measurement
range are computed.
p5 handling of data for TLOG.PSUM(only
for PULSE input module)
OVER A result of the computational
expression TLOG.PSUM
(XXX) exceeding 99999999 as
an overflow
ROTATE
A result of the computational
expression TLOG.PSUM
(XXXX) exceeding 99999999
to continue computing with the
value following 99999999
reset to 0.

Example Compute computation error as +OVER and TLOG
computation scale value as off, and ignore
abnormal data in a channel and overflow data in a
channel for computation and a result of the
computational expression TLOG.PSUM (XXX)
exceeding 99999999 as an overflow.

Comments • This command only works with the optional
computation function or if a pulse module is
installed.
• p2 is effective for the totalization of flow
signals, which are expressed in engineering
units /s, /min, /h.
If p2 is set according to the input unit, the
measurement data are computed based on that
unit at the specified measurement intervals. For
example, set the measurement interval to 2s,
the input value to 100 m3/min, and p2 to /MIN.
By doing this, because 2s/60s is multiplied for
each measurement interval, then after 1 minute,
approximate actual input values are obtained.

Comments • p2 is set with number of the first relay (fixed to
01), and that of the last relay.
• The relays specified here can only be turned
ON/OFF by using the VD command.
• Configurations such as alarm reflash, AND/OR,
and hold are ineffective for the relays specified
here.

Example Store a parameter set in the setup mode in
NVRAM.
XESTORE
Comments • A parameter set in the setup mode becomes
ineffective in its setting if the mode is changed
without STORE. After setting all parameters
in the setup mode, be sure to store the set data
in the internal memory using the XE command.
In addition, after normal processing with the
XE command, the mode is transferred to the
operation mode.
• Since execution of the XE command takes an
indefinite time, return an ACK after the
processing is completed. On the controller side,
execute the next processing after receiving an
ACK after transmitting the XE command. The
ACK status format is as follows:
