Commands

6

• If the daily report is to be output using extended

format, the extended information must be
output within 1 hour from the creation of the
report. If the monthly report is to be output
using extended format, the extended
information must be output within 1 day from
the creation of the report. After that, the
extended information can not be output.

• If there is no valid data within the specified

report channel range, "FFFFH" is output.

LF

Specifies the output channels for
setting data output, unit, and decimal
point data.

Mode

All modes

Setting

LFp1, p2<terminator>

p1

First output channel (001 to 560)
First output computation channel (A01 to
A60)

p3

Last output channel (001 to 560)
Last output computation channel (A01 to
A60)

Comments

• Be sure to specify data to be output with the TS

command and execute “GET” or “ESC T”
before transmitting the FM command.

• If there is no input channel recognized by the

DA100 among specified channels, a syntax
error occurs.

• For stand-alone models computaion channel

number is A01 to A30.

CF

Specifies the system
configuration output format.

Mode

All modes

Setting

CFp1<terminator>

p1

0 Information on system-configured

module

1 Current status module information

(realtime information)

Comments

• Be sure to specify data to be output with the TS

command and execute “GET” or “ESC T”
before transmitting the CF command.

VF

Requests the output of the relay
condition.

Mode

Operation mode

Setting

VFp1<terminator>

p1 0 Current relay condition

Comments

• Before sending the VF command, make sure

to specify the output data with the TS command
and execute “GET” or “ESC T.”

BO

Specifies the order of byte output
(in binary output).

Mode

Operation mode

Setting

BOp1<terminator>

p1

0 Output from MSB (upper-digit byte)
1 Output from LSB (lower-digit byte)

IM

Specifies the mask of a status byte.

Mode

Operation mode

Setting

IMp1<terminator>

p1 First numerical value of the items( or

combination of those value) shown below.
0

sets all causes of interrupt to off.

1

Interrupt occurs at the end of an A/D
conversion.

2

Interrupt occurs at the time of a syntax
error.

4

Interrupt occurs when internal timer is
being operated or the time for hourly,
daily and monthly reports arrives.

32 Interrupt generated when measurement

release is generated while computation
is in progress.

Comments

• Masks the causes of interrupt in the status byte.
• When either of the phenomena effectively

specified with this command occurs, bit 7
(SRQ) of the status byte is set to “1” and causes
an interrupt to the controller.

• For detailed instructions on the status byte, see

page 2-2.

SM

Sets the auxiliary mask of the status
byte.

Mode

Operation mode

Setting

SMp1<terminator>

p1 A figure determined by the following
calculation:

p1 = a + b + c + d + e + f + g

a=1

Interrupt occurs when timer No. 1
operates.

=0

No interrupt occurs.

b=2

Interrupt occurs when timer No. 2
operates.

=0

No interrupt occurs.

c=4

Interrupt occurs when timer No. 3
operates.

=0

No interrupt occurs.

d=8

Interrupt occurs when timer No. 4
operates.

=0

No interrupt occurs.

e=16 Interrupt occurs when timer No. 5

operates.

=0

No interrupt occurs.

f=32 Interrupt occurs when timer No. 6

operates.

=0 No interrupt occurs.

g=64 Interrupt occurs when the time for

hourly, daily and monthly reports
arrives.

=0

No interrupt occurs.

Comments

• Sets the auxiliary mask of interrupt when the

timers described in the IM command operate.

• When any of the timers whose numbers are

specified with this command operates, an
interrupt due to the internal time operation
occurs.
