6.1 Setting Command

• The measurement range cannot be changed

while executing a report or computation.

Setting the strain input scaling

Setting

SRp1, p2, p3, p4, p5, p6, p7, p8, p9<terminator>

p1 Channel number (001 to 560)
p2 SCL
p3 STRAIN
p4 Measurement range

2k/20k/200k

p5 Left value of span
p6 Right value of span
p7 Left value of scale

(-30000 to 30000)

p8 Right value of scale

(-30000 to 30000)

p9 Decimal point position of scale (0 to 4)

Example

Measure using the measurement range of 2k for
subunit 0 and channel 01, and convert 0

µε

to 0.00

and 1000

µε

to 100.00.

SR001, SCL, STRAIN, 2k, 0, 1000, 000,

10000, 2

Comments

• Even when the settings of p4 are same

parameters, the measurement range of the strain
varies depending on the gauge method. For
details, refer to page 5-7.

• Set spans p5 and p6 within the measurement

range indicated in page 5-7.

• Input values up to 6 digits disregarding the

decimal point for p5 and p6. The decimal point
position is fixed to the decimal point position
of the setting range of page 5-7.

• For p7, p9, and p10, either set all the three

parameters or omit all three.

• The measurement range cannot be changed

while executing a report.

• The measurement range cannot be changed

while executing a report or computation.

SN

Sets the scaling unit.

Mode

Operation mode

Setting

SNp1, p2<terminator>

p1

Channel number (001 to 560)
Computation channel number (A01-A60)

p2

Unit character string (up to 6 characters)

Example

Set the scaling unit of subunit 0, channel 01 to
ABCDEF.

SN001, ABCDEF

Comments

• For a character string that can be used as units,

see the characters in Section 5.6, “ASCII Code
Table.”

• For stand-alone models computation channel

number is A01 to A30.

SA

Sets the alarm.

Mode

p1

Channel number (001 to 560)

p2

Level (1 to 4)

p3

Type of alarm

OFF

No alarm setting

H

Upper limit

alarm

L

Lower limit

alarm

dH

Alarm for upper limit of

difference

dL

Alarm for lower limit of

difference

RH

Alarm for limit of

increasing rate-of-change

RL

Alarm for limit of

decreasing rate-of-change

p4

Alarm value

p5

Output relay number (Off or relay
number)

Example

Set the upper limit alarm (alarm value=1000) to
level 1 of subunit 0, channel 02 and have relay
module 1 be in slot 6 of subunit 0 when an alarm
is generated.

SA002, 1, H, 1000, 051

Comments

• If the input range setting is SKIP, the setting of

p3 can only be set to Off.

• In the following cases, alarm settings in that

channel are all canceled.
• Change of the type of input (VOLT, TC .....)
• Change of the input range
• Change of the indicating span or scaling

value when the scaling indication is set
(including a change in decimal point
position)

• In differential input or RRJC, a change in

reference channel number or type of input/
input range

• When the computational channel is set to on

or off, or the computational expression or
measuring span is changed.

• When the wiring method and the input range

of the power monitor module are change

• When continuous has been selected for a

channel at p1 and the measurement ranges
differ, the decimal point of the alarm value will
be decided by each measurement range (Refer
to page 5-6, 5-7).
If the value exceeds the resulting permissible
measurement range, an error will occur.
For example, when the measurement ranges of
the channels set to p1 are 20mV, 2V, TC type
T, and the alarm value is set at 10000, then the
situation becomes as follows;

• The alarm value for the channel with the 20mV

measurement range becomes 10.000mV.

• The alarm value for the channel with the 2V

measurement range becomes 1.0000V.

• The alarm value for the channel with the TC

type T measurement range becomes 1000.0

°

C.

Since the measurement range of TC type T
ranges from –200

°

C to 400.0ºC, an error occur.

For details about the decimal point, refer to page
5-6 to 5-9.

• If p3 is off, the parameters for p4 and p5 are

invalid.

• For the computation channel, the only alarms

that can be set are the high-limit alarm (H) and
low-limit alarm (L).

• The dH or dL setting for p3 is effective only

when the input range is a differential input.

• If p3 is set to RH or RL, set the interval with

the XA command.

• The setting ranges of p4 alarm values are those

on page 5-6 to 5-9.

• Enter the p4 alarm value with characters up to

6 digits excluding the decimal point.
