SMS/EMAIL/GPRS/IP ALERT AND MONITORING MODE
PM020 support dual operating mode :
a) Direct Alert 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.
When SMS Acknowledgement is turn on, the user will need to acknowledge SMS or else up to 5 level of SMS will be send at user set intervals. If the SMS are not acknowledge after the maximum duration of acknowledgement windows, the SMS will be escalate to the Escalation group.
b) Server Mode: Send to Testech TSCADA CMS 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 and Broadband IP connection. Testech support BOTH Dynamic IP and Static IP.IP Camera can be added to Testech TSCADA SQL Server.
In logging mode or interface to Metering devices, the PM020 regularly read or poll data and send to server using either compressed PDU format SMS, or using GPRS for larger payload packet.
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 PM020
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 COMMAND FOR REMOTE SETUP
User can send SMS (which has to be validated for a existing phone number in the PM020) 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 Digital Output etc.
SMS Command supports includes allowing remote authorised Handphone to configure, setup, add/edit/enable/disable/delete handphone numbers etc.
GROUP CONFIGURATION AND ASSIGNMENT
Up to 2 Group of 10 Phone Each (that is total of 20 GSM Phone Number) can be setup on the RTU (via RS232C or Keypad)
Group can be set to Server Mode (requires TSCADA HMI 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 20 GSM Phone number can be created in the PM020 RTU, by assigning up to 10 Phone Max to Each group (max 2 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).
Input Connector usng high quality 3.8mm Pluggable Industrial Terminal connectors for fast removable screw connects.
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 (PM020)
Each Analog Input resolutions is 12bit instrumentation grade Aanalog To Digital Converter accepts unipolar (4-20mA/0-5VDC switchable).
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 2 points digital calibration for the best linearity. During calibration, the value read in are compare against against accept value.
PM020 uses FULL Digital calibration and there is no TrimPot or Potentiometer. Therefore the long term stability of ADC reading is very good.
PM020 has High Current 2 Transistor output for driving External Digital Load such as relay, buzzer, siren, PLC etc. The digital output Configuration allows the output to be driven base on input conditon or SMS. Output can have a user set pulse timming.
USB Windows Interface
The PM020 is unique in the sense that it has a built in USB HID (Human Interface Device) that is supported by all version of windows since windows XP, Vista, Windows7. This allows fast communication interface to PC and supported by a free windows configuration software that allows even novice users to be able to setup the RTU with ease.
Changes made can be save into PM20 interval Non Volatile Memory to permanently store the setup.
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 individually time stamed and store in the event log in the internal non volatile Flash Memories, and using the addtional built in 2MByte Non Volatile Flash Memories, unlimited event log is possible.
RS232C / RS485
The PM020 has a External RS232C (factory installed option to change to RS485) to allow interface to external Metering Devices, Sensors, PCs., Please talk to us for any custom interfacing including ModBus Protocol, Hart Communcation protocol.
OPTIONAL SCADA (WINDOWS/WEBSERVER/IP CAMERA)
The WebBase or Windows Base are SCADA developed by Testech Electronics has allows many units of PM020 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 custom HMI has been developed for Data Monitoring, Water Qualities, Flood level Monitoring, Weather Stations, Turbidity sensors, Volatile Organic Compound, RainGauge etc. Each parameter of the SCADA IOs can be modify to suit user sensors.
TSCADA support DVR and IP Camera for real time streaming videos integrated into the SCADA remote Monitoring.
