Yokogawa DA100 - Manual (Page 39)

4-10 IM DA100-11E
The alarm status indicates two levels with one byte.
1 byte
Level2 Level1
Upper Byte Lower Byte
1 byte
Level4 Level3
Upper Byte Lower Byte
D1 to Dn, H1 to Hn: Alarm status (level 3, 4) (No output when p1 is 0)
Contents and format are the same as level 1 and 2.
E1 to En: Fixed to 80H
F1 to Fn: Computation channel number
The measured/computed data are output in the order specified by the EB com-
mand.
Measured data
7FFFH (7FFF7FFFH): Positive over-limit data
8001H (80018001H): Negative over-limit data
8002H (80028002H): Measurement range setting skips.
8004H (80048004H): Abnormal data
8005H (80058005H): No data
*Data inside the parentheses ( ) are computed data.
EL Specifies the channel for outputting unit and decimal point informa-
tion and outputs it in ASCII format
Mode Operation mode
Syntax ELp1, p2<terminator>
p1 First channel to output (001 to 560, or A01 to A60)
p2 Last channel to output (001 to 560, or A01 to A60)
Description • A01 to A60 correspond to computation channels (A01 to A30 for the stand-alone
type).
• The data of expansion type channels that are not connected are not output.
• If there are no corresponding channels, E1 is returned.
• The unit and decimal information is not determined if measurement channels are
skipped or if abnormal data exist.
• The output format is as follows.
S1S2CCCUUUUUU, PCrLf
S1: Space (fixed)
S2: Data status
Space Intermediate data
E Last data
CCC: Channel number (3 characters)
001 to 560 or A01 to A60
UUUUUU: Unit (6 characters)
P: Decimal point position
0 00000
1 0000.0
2 000.00
3 00.000
4 0.0000
EB Specifies the byte order of output.
Mode Operation mode
Syntax EBp1<terminator>
p1 Byte order of output
0 MSB first (Default setting)
1 LSB first
Description • Sets the byte order of the binary data of the measured/computed data that are
output with the EF command.
• Since the DA100 determines the upper byte and lower byte in units of two bytes,
four-byte data are output as follows.
MSB first: ABCD
LSB first: BADC
