Set conditional alarm to trigger if corresponding flag is set. Also must set high and low threshold.
read-write,
yes-no
Flag to set corresponding out-of-range alarm. "1"
turns on flag, and "0" turns off.
Show or clear the out-of-range flags. When set, the device will respond to a conditional search. Clearing the flags is performed with the EDS00XX/alarm/clear command, not just having the measured value return to the center range.
write-only,
yes-no
Write "1" to clear ALL the alarm flags.
read-only,
yes-no
Show corresponding out-of-range alarm. "1" means
in alarm state. Can only be turned off with clear
Optionally found on the EDS006X and EDS007X. Can be controlled by software or the alarm condition.

|
0 |
alarm control with hysteresis |
|||
|
1 |
alarm control but need EDS00XX/alarm/clear to unset |
|||
|
2 |
Control with EDS00XX/relay/state |

read-only,
unsigned integer
Approximate samples since power up.
read-write,
binary
96 bytes of memory. Not all is writable. Access to
EDS00XX functions is better accomplished through the
data fields, which expose all the chip features.
read-write,
binary
Memory is split into 3 pages of 32 bytes each. Only page 2
is writable. ALL is an aggregate of the pages. Each
page is accessed sequentially.
read-write,
binary
160 bytes of memory. Not all is writable. Access to
EDS008X functions is better accomplished through the
data fields, which expose all the chip features. The
EDS008X has more memory than the other chips, so a
separate entry in the sudbirectory makes it available.
read-write,
binary
Memory is split into 5 pages of 32 bytes each. Only page 5
is writable. The EDS008X has more memory than the
other chips, so a separate entry in the sudbirectory makes
the extra pages available. ALL is an aggregate of the
pages. Each page is accessed sequentially.
read-only,
ascii
Text description of the device. Up to 30 characters.
read-only,
ascii
Device name. E.g: "EDS0071"
read-only,
unsigned
Number corresponding to the hexadecimal type. E.g:
EDS0071 -> 0x0071 -> 113 in decimal
None.
The EDS00XX sensors are a family of devices from Embedded Data Systems. Although provisional support for several types is included, only early EDS0071 has been tested with OWFS.
The sensors all share the same 7E family code. They have the same first memory page layout with a text tag property that describes them, and a sub-type field giving the particular sensor. The data properties shown in a directory listing will be specific to the sensor sub-type.
The EDS0071 (3) is a micro-processor based 1-wire slave made by EDS (Embedded Data Systams). Is uses a high accuracy and extended range RTD sensor to accurately measure temperatures.
The EDS00XX sensors are read and controlled by accessing parts of their on-chip memory. Although the raw memory contents are exposed in the memory and pages fields, all the available functionality is best accessed by the other fields. In fact, directly changing memory will confuse OWFS.
All the EDS00XX sensors have an LED and optional relay. Both can be controlled either directly, or when the sensors reaches an alarm state.
