Information SMSs for meter connected to the digital input port
If the digital input was configured to send information SMSs
upon a user request message (see “Interface configuration”
section), then the following SMS will be sent:
“<INSTRUMENT DESCRIPTION>; Digital input; <DESCRIP-
TION FOR THE DIGITAL INPUT STATUS>; Rem msg:
<NUMBER OF REMAINING MESSAGES>”.
<INSTRUMENT DESCRIPTION> field is the same as for the
alarm SMS; <DESCRIPTION FOR THE DIGITAL INPUT STA-
TUS> is one of the two description strings defined by the user
with
HI504901SW
software on last interface configuration re-
lated to present digital input status (close or open).
Here is a message example: “HI8711-A; Digital input; pH IS
OK; Rem msg: 32”.
Note
If no information is available regarding an instrument be-
cause it did not answer to
HI504901
during last polling
procedure, then the following “Device not responding” string
will appear for <INFORMATION SPECIFIC TO THE INSTRU-
MENT> field.
Note
If no error is active on current device, then the text string “No
alarms” will be added instead of the list of active alarms.
Note
If SMS sending is disabled through the external switch, then
HI504901
sends only the message: “SMS disabled; Rem
msg: <NUMBER OF REMAINING MESSAGES>”.
Note
The information about SIM charge and expiration date are
not saved in the SIM card, but are managed by the network
operator; the instrument can not get directly the information.
To prevent the discharge of the SIM card, the user has to
configure manually (according with the credit stored on the
SIM card) the maximum number of SMSs that can be sent
(see “Interface configuration” section).
Note
Every time an SMS is submitted, the <NUMBER OF REMAIN-
ING MESSAGES> is updated and it will always indicate the
remaining number of messages that can be sent by the in-
strument. When this number is going to reach zero, the mes-
sage “Maximum number of SMSs reached. Please check the
HI504901 SIM charge level; Rem msg: <NUMBER OF RE-
MAINING MESSAGES>” will be sent by the instrument to
the programmed cellular phone number(s). This particular
situation is managed as an error occurrence and a confir-
mation is waited. When this happens, no more messages will
be sent by the interface until the error is disactivated.
list of all active alarms with the previously described format (see
section “Alarms for HI8001 and HI8002 controllers”).
Information SMSs for HI700, HI710, HI23 and HI24 meters
For these meters the <INFORMATION SPECIFIC TO THE
INSTRUMENT> field reports the following information:
• “EC: #### uS or mS”: EC reading, available only when
the meter is in control or idle mode; the measure unit, uS
or mS, depends on the scale used by the instrument; if the
reading is out of meter range, then this indication will be
“EC:---- uS or mS”;
• “Temperature: ##.#C”: temperature reading; if the meter
is not in control or idle mode, the controller answers with
the last acquired reading when it was in control or idle
mode; if the reading is out of meter range, then this indica-
tion will be “Temperature:----C”;
• “TDS: #### ppm or ppt”: TDS reading, available only
for
HI710
and
HI24
devices in control or idle mode; the
measure unit, ppm or ppt, depends on the scale used by
the instrument; if the reading is out of meter range, then
this indication will be “TDS:---- ppm or ppt”;
• “Alarm on”: if an alarm is active on current device.
Note
If the meter is in control or idle mode, no information is avail-
able for EC and TDS values, and indication as that for read-
ing out of range will be given in the alarm SMS.
Information SMSs for HI504 and HI504910 meters
For these meters the <INFORMATION SPECIFIC TO THE
INSTRUMENT> field reports the following information:
• “ORP: #### mV”: ORP reading, available only if the meter
is set as ORP controller; if the reading is out of meter range
(±2000 mV), then this indication will be “ORP: ---- mV”;
• “pH: ##.##”: pH reading, available only if the meter is set
as pH controller; if the reading is out of meter range (-2.00 to
16.00 pH), then this indication will be “pH: ----- ”;
• “Temperature: ###.#C”: temperature reading, available
only if the meter is set as pH controller; if the reading is out
of meter range (-30.0 to 130.0°C), then this indication will
be “Temperature:-----C”;
• “HOLD”: hold indication, if the controller is in hold mode;
• List of all active alarms as previously described (see “Alarms
for HI504 meters” section).
