APPLICATION AREA
Computer Data Center: Monitoring Computer, UPS, PC Server, Water
Leak, FM200, Temperature/Humidity.
SCADA System (Water Level, Flood Monitoring, Water Quality (PH,
DO, Turbidity, Temp), VOC, TOC and other kind of Sensor Measurement
Weather Stations (Rain Gauge), Slope Movement.
Remote Event Alarm Notification. (UPS, Cold Room, Refrigeration,
Electrical, Breaker, Solar Panel, Security Panel, Fire Alarm Panel, Lift
Monitoring).
Remote System Reset via Wireless Means. The Relay output
contact can be used to remotely reset your system or activate your remote
system external trigger.
FLEXIBLE ASSIGNMENT OF IO TO GROUPS
Group of Phone/Email can be created such as each group can be enable/disable
as well as assigned to specific IOs that will trigger the alert.
SMS Alert MONITORING MODE
PM052 support dual operating mode:
a) Direct SMS Message Send to User Handphone.
When Alarm Event occurs, Message are compose and then send
directly to user handphone. The number of failed Send SMS can be set to
automatically retry sending after a user specified interval. Each User can be
alert via SMS . Each Person can be assign to Group, and each group can
be assign to combination of inputs that will trigger an alert.
b) Server Mode: Send to Testech TSCADA HMI
When Alarm Event occurs, Message are compose and compressed and
then send to Testech HMI Software running at the customer central monitoring PC
equipped with a SMS/GPRS Modem and Broadband IP connection. Testech support BOTH
Dynamic IP and Static IP.
This means that with our RTU you are assure of the best in both world of
operating in standalone mode, Server Mode, and BOTH SIMULTANEOUS User+Server
Mode by creating different Phone/IP group on the PM052.
The important implication is that our RTU is scalable, allowing customer to
gradually scaled up the unit of deployment from standalone base to server base.
SMS QUERIES
User can send SMS (which has to be validated for a existing phone number in
the PM052) can be send to querrie or activate the IO Control, as well as
checking the system status including Telco signal strength, status of GPRS
Connection, turn ON/ Turn off the relays etc.
GROUP CONFIGURATION AND ASSIGNMENT
Up to 8 Group of 10 Phone Each (that is total of 80 GSM Phone Number) can be
setup on the RTU (via USB Serial or Keypad)
Group can be set to Server Mode (requires TSCADA Software) or User
Mode (diret SMS Message Alert to user Mobile Phone)
Group can be Enable or Disable.
Inputs assignment can be assigned to each Group. For example if the
RTU are connected to mechanical equipments, HVAC and electrical equipment
etc and there are different team of maintenance responsible for each
category of equipments, you can then alert ONLY the team that are
responsible for the particular input that requires service attention when a
alarm is send out via SMS
Each group and each individual phone can be individually enable and
disable. Inputs can be assigned to different group.
PHONE CONFIGURATION AND ASSIGNMENT
Total of 80 GSM Phone number can be created in the PM052 RTU, by
assigning up to 10 Phone Max to Each group (max 8 Groups).
Each Phone can be assign two different privilege mode
Supervisor Phone: Supervisor Phone can configure the unit and send
control command to the unit (Turn Alarm ON/OFF, switch RTU to Online GPRS
Mode, Switch RTU to OffLine SMS Mode, Turn Relay On,
Change Phone Number, Enable/Disable Phone, Enable/DIsable Group)
User Phone: User Phone are only allow to receive alarm message via SMS or
Poll the System (for example to check the input status again, or health
check).
INPUT CONNECTORS.
Input Connector usng high quality 3mm connectors for fast removable screw
connects. LED indication shows the status of the Latch Relay ON/OFF status.
DIGITAL INPUT CONFIGURATION AND ASSIGNMENT
Each Input can be individually setup to trigger SMS/EMAIL on Low, High, Alarm
Limit Low or Alarm Limit High.
System and IO Status can be check by sending a SMS message to check RTU
Health Status
System can be ARM, DISARM for maintenance.
ANALOG INPUT CONFIGURATION AND ASSIGNMENT (PM051)
Each Analog Input resolutions is 16bit instrumentation grade Aanalog To
Dgiital Converter accepts directly 4-20mA Input.
Each Analog Input can trigger an alert due to High Limit, Low Limits or
both.
Hysterysis allows user to change the band of changes that that it allows
allowance as the alarm cross the boundary of each Alarm Limits to capture
for Analog sensor that hover around the limits.
Analog Alarm can be assign to individual group.
Each Channel can be individually configure for zero and span,
engineering scaling.
Engineering Scaling: The Low Reading and Full Scale Reading can be scaled
to user Engieering Units up to 4 digitals + 1 decimal Place (-9.999 to
+999.9)
Low Alarm and Hysterisis: Low Alarm can be set with hysterisis (that is
if input falls below the Low Alarm trip point), SMS wll be send and the
Alarm will only be clear if input reovers to Low Alarm trip point +
hysterisis.
High Alarm and Hysterisis: High Alarm can be set with hysterisis (that is
if input rises above the High Alarm trip point), SMS wll be send and the
Alarm will only be clear if input reovers to Low Alarm trip point +
hysterisis.
ANALOG ADC CALIBRATION
The ADC can be calibrated by the user by using a Process calibrator. Each
ADC has 5 points digital calibration for the best linearity. During
calibration, the value read in are compare against against accept value.
PM052 uses FULL Digital calibration and there is no TrimPot or
Potentiometer. Thefore the long term stability of ADC reading is very good.
RELAY OUTPUT
PM052 has 4 Relay Output able to handle up to 2.5A current @ 24V. Each Relay
Output are protected by resettable fuse that will not require user to
replace fuse. This relay can
be user for example interface to external Light Pole, Siren, Reset External
Equipment etc. Optionally Input can be assign to relay to activate the relay
for example to activate siren or light pole.
The Relay are Latching Type (it will retain its ON/OFF condition even
when power off)
These Relays are easily Map to Digital, Analog, Power, EdgeDetect, IP
Ping Results using the websetup and user can program the logical expresssion
to turn on/off the Specific Relays (for example IF D1 OR D2 OR A1 is ALARM
condition THEN turn Relay#1 ON).
Likewise relayout Output can be manually Turn ON/Off by user via Web interface
or SMS, for example to turn on machines, aircon, lights etc.
USB Interface
Console interface using any Serial Terminal Software such as Windows
HyperTerminal for interactive login, system setup,
maintenance check, and configure of Input Description, Alarm Trigger, Group,
Phone Number.
Changes made can be save into PM05x interval Non Volatile Memory to
permanently store the setup.
EVENT LOGGING
All Event (System Login, System Reset, IO Event, Send SMS Operations etc)
are logged and save in battery backup memory. By Default, up to 100 event are invidually
time stamed and store in the event log in the internal non volatile Flash
Memories, and using the addtional built in 32MByte Non Volatile Flash
Memories, unlimited event log is possible.
RS232C And RS485
The PM052 has a External RS232C to allow interface to external
peripheral and equipment such as datalogger, please talk to us for any
custom interfacing including RS232C/RS485. For example we can interface to
GPS/Datalogger/Swipe Card Reader etc.
INTERFACE TO TEMPERATURE AND HUMIDITY SENSOR
The PM052 directly interface to a digital temperature/RH Thermohygrometer.
No analog channel is required.
Temperature: -20 to +85°C +/- 0.5°C, 0.0625°C resolution.
Humidity: 0 - 100% RH +/- 0.6%RH, 0.04% RH resolution
Built in Hydrophobic Filter Protects Sensor Against Dust, Dirt, Moisture,
and Contaminants
Sensor are individually calibrated in a NIST-Traceable Chamber
MicroSD Interface
Optionally MicroSD Interface allows removable datalog storage media in order to
upload data to PC. Support FAT16 up to 2GB MicroSD Media
EXPANDABLE IOs
Additional IO can be expanded and connect to the PM05x to support up to
16 external IO Modules (that is up to 16 x 16 digital inputs = 256 digital
inputs). Digital INput are optoisolated. Combination of Opto Isolated
Digital In, Digiout Out, Analog Input are supported.
OPTIONAL SCADA (WINDOWS/WEBSERVER/IP CAMERA)
The WebBase or Windows Base developed by Testech Electronics
has allows many units of PM052 to be monitor from one central server using
enterprise level SQL server. User Phones/Email are store on the Server, and
the unit monitor and logs all the RTU on 24/7 basis.
Specific sustom HMI has been developed for Data Monitoring, Water
Qualities, Flood level Monitoring, Turbdity sensors, Volatile Organic
Compound, Weather Stations etc. Each parameter of the SCADA IOs can be
modify to suit user sensors.
SCADA support DVR and IP Camera for real time streaming videos integrated
into the SCADA remote Monitoring.
