• If the action mode is set to LEVL and the action is

set to RECORD, SPEED_CHG, GR_TREND, or
MATH,REPORT, FLAG, the set action continues
from the first event occurrence to the next event
occurrence.

• If the event is set to TIMER, MFUNC_KEY or

MATCH_TIME, the action mode to LEVL, and
the action to RECORD, the set action continues
from the first event occurrence to the next event
occurrence.

• For details on an event/action, see the separate

manual (IMDR231-01E or IM DR232-01E).

Sets the computational expression.

Setting

Channel for computation:
Stand-alone model - A01 to A30
Expandable model - A01 to A60

Span right value (-9999999 to

Position of decimal point for span (0

to 4)

Example 1

Set the sum of channel numbers 001 and 002 to
channel A01 for computation. Set

-10.0000 to

15.0000 for the span.

SOA01, ON, 001+002, -100000, 150000, 4

Example 2

Set the data in channel number 003, which are stored
in the built-in RAM disk to
channel number A02 for computation. Set -100,000
to 150.000 for the span.

SOA02, ON, M003, -100000, 150000, 3

Comments

• This command is effective only with optional

computation functions or a floppy disk drive
function or with a pulse module installed.

• With a floppy disk drive function applied, if you

attempt to read data stored on the floppy disk
drive, assign a new channel number to the
computation expression.

Measurement date

M001 to M030 (stand-alone model)
M001 to M300 (expandable model)

Computation data

MA01 to MA30 (stand-alone model)
MA01 to MA60 (expandable model)

• With a floppy disk drive function applied, but

without computation functions, you cannot use
operators. For operators, see the Appendix at the
end of this manual.

• If pulse modules are installed and there is no

computation function, TLOG.PSOM will be the
only valid operator.

• If you wish to omit either p4, p5, or p6, omit them

all together.

• If successive channels are set, place a “-” (hyphen)

between the first and last channels.

Sets the computational constants.

Mode

Operation mode

Setting

SKp1, p2

Computational constant number:

Stand-alone model - K01 to K30
Expandable model - K01 to K60

Constants

Example

Set 300 to a computational constant K10.

SKK10, 300

Comments

• This command is effective only with the optional

computation functions.

• Constant setting ranges are -1.0000E35 to -

1.0000E-35, 0, 1.0000E-35 to 1.0000E35.

Sets communication input data.

Mode

Operation mode

Setting

CMp1, p2

Communication input data number:

Stand-alone model — C01 to C30
Expandable model — C01 to C60

Numeric value: -32000 to 32000

Example

Set 300 to the communication input data number
C10.

CMC10, 300

Comments

• This command is effective only with the optional

computation functions.

• The position of the decimal point is selected

according to the position of the decimal point set
for the span with SO command. So you can set
communications input data without taking the
decimal point into consideration.

Sets the channel for setting data that
are stored on a RAM disk.

Mode

Setting

MHp1, p2

Channel number/channel number for
computation

On/off

Example

Assume that the setting data in channels A01 to A05
for computation are stored.

MHA01-A05, ON

Comments

• This command is effective only with a floppy disk

drive function.

• If successive channels are set, place a “-” (hyphen)

between the first and last channels.

• Channel numbers are recognized in the order of

input channel and channel for computation. If
005-A10 is set, the objective channels that are set
are from input channel 005 to the last channel
including channels A01 and A10 for computation.
