Operate on either Standalone, Server Base or Combine Standalone + Server Base.

APPLICATION AREA

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.

Operation Mode

PM04x 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.

b) Server Mode: Send to Testech SMSMONV2 HMI Sotware
   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. Using GPRS has the added advantage that the Remote Monitor can be an online systems (that is continous update on the PC). Note that GPRS typicaly requires user to have subscription service to Telco unlike of the shelve PrePaid SIM Card.   

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 PM04x..

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.                               

GROUP CONFIGURATION AND ASSIGNMENT

Up to 6 Group of 5 Phone Each (that is total of 30 GSM Phone Number) can be setup on the RTU (via RS232C or Keypad)

Group can be set to Server Mode (requires SMSMONV2 HMI Software) or User Mode (diret SMS Message Alert to user Mobile Phone)

Group can be Enable or Disable.

Inputs assignment can be asigned 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 30 GSM Phone number can be created in the PM04x RTU, by assigning up to 5 Phone Max to Each group (max 6 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, Snap Pictre, 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).

DIGITAL INPUT CONFIGURATION AND ASSIGNMENT

Each Input can be individually setup to trigger SMS on Low, High, Alarm Limit Low or Alarm Limit High.

System Status can be check by sending a SMS message (?SQ) to check RTU Health Status.

System can be ARM, DisARM for maintenance.

ANALOG INPUT CONFIGURATION AND ASSIGNMENT (PM041)

Each Analog Input resolutions is 16bit instrumentation grade Aanalog To Dgiital Converter accepts unipolar (0-5V). 4-20mA can be measure by connecting a 1% 250ohm resistor to convert the input to 1-5V.

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 voltage calibrator. Each ADC has 5 points digital calibration for the best linearity. During calibration, the value read in are compare against against accept value.

PM041 uses FULL Digital calibration and there is no TrimPot or Potentiometer. Thefore the long term stability of ADC reading is very good.

RELAY OUTPUT

PM041 has 1 Relay Output able to handle up to 2A current. This relay can be user for example interface to external Light Pole, Siren, Reset External Equipment etc.

CAMERA

PM040 or PM041 canbe optionally factory installed with a digital camera onboard to allows user to snap picture (preview picture or Max VGAx640 pixel resolution). Picture taken can be send via GRPS back to SMSMONV2 HMI Software

PC Interface (RS232)

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 PM04x 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. Up to 100 event are invidually time stamed and store in the event log.

RS232C/RS485

The PM04x has a optional 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.

ETHERNET LAN

In Proccess of implementation, FULL TCPIP stack with Ethernet LAN 10BT, for Wired LAN remote Monitoring application and built in HTTP WebServer.
