Note: Poseidon model 1140 was replaced by model Poseidon 2250.

The Poseidon model 1140 is designed for watching temperature, humidity and other sensors (up to 42). You can watch each sensor's critical values. In case the sensor goes out of the Safe Range, Poseidon notifies the operator by sending a SNMP trap (UDP paket). Typical applications for Poseidon are supervising stocks or warehouses, 19" racks, or cable collectors. Poseidon Measures Temperature (up to 42 sensors which can be distant up to 1,000 meters from the device, temperature range -55 °C .. +640 °C) Humidity (up to 25 sensors, up to 1,000 meter distance) Digital input/contact (sensors of smoke, vibration, motion, submersion, declination, opening/closing door, air flow etc.) General input (0..10V, 4..20mA – using external converters to RS-485)   The device is controlled from a graphical interface - try the online version: http://80.250.21.84.

Basic features of the 1140 model

• You can access up to 42 sensors over Ethernet (Internet), using protocols such as SNMP, XML, WEB, Modbus/TCP and more..
• You can connect up to 42 sensors to one Poseidon unit, you don't need to upgrade the unit to connect additional sensors.
• Many sensors available, cheap simple sensors form home use, or complex industrial sensors with 0,15 °C accuracy and range from -50 to +640 °C.
  • Sensors can be distant up to 1.000 meters (RS-485) from the Poseidon itself
  
• The device can be remotely configured over graphical www interface
• Security can be ensured by access passwords or predefined IP address range.
  Any device's configuration change can be denied with a DIP switch.
   
• A standard SNMP device, sophisticated MIB supporting joint requests
• As soon as any value is out of range, the device sends a UDP SNMP Trap
• You can connect standard industrial sensors (Pt100, thermoelement, current loop 4..20 mA, voltage 0..10V)
• FirmWare can be updated over WWW or RS-232, latest version can be downloaded from our website.
  
• For our OEM partners it’s possible to change the design of HTML pages as well as the contact lists etc (you have to order more then 50 pcs).
• If you need measured values logging, ask us about the Poseidon2, which stores the measured values into its internal 512kB Flash memory.

• Environment monitoring in intelligent buildings
• Air-condition devices supervising
• Storage premises monitoring
• Telecommunication devices (transmitters, PBX)

Poseidon 1140 system topology

SW for reading out the measured values

The measured data can be accessed over TCP/IP and UDP/IP using these protocols:

	The values and sensor's states are displayed on a WWW page, which reloads every 5 seconds. From the main page, there is a link to the Flash setup, FW update, etc...
	The values and sensor's states are in an .XML file (values.xml) available for any application. More information about XML.
	SNMP is a protocol for supervising telecomunication devices, network infrastruktures and other technologies. Poseidon can be fully controlled using SNMP (v1, some parts from v2) - more information.
	If any value exceeds the "Safe range", the sensor will go to an alarm state and it sends a SNMP trap to a predefined IP address - more information.
	Modbus/TCP is an industrial standard for sensors and visualisation and SCADA systems. All the sensor's values are accessible over Modbus/TCP - more information.

You can find more detailed description obout these interfaces and Poseidon software here: Poseidon – communication interfaces .

HW interfaces for sensors of the Poseidon device

K You can connect the sensors to several buses at once, using a wide variety of sensors, from simple home thermometers up to proffesional industrial sensors. You can find more information in the sensor's overview.

• Digital inputs
  3 inputs for door contact, relay outputs of any other binary sensor.
• RS-232
  1 sensor up to 20 meters distant, the interface is used mainly for device setup.
• 1-Wire
  Interface for connectiong up to ten simple sensors distant up to 15 meters from the device.
• RS-485
  You can connect the desired sensors to the RS-485 bus, which can be up to 1000 meters long. If you use proper converters, you can connect current loop sensors (4..20 mA), or platinum sensors like Pt100, Pt500, Pt1000 (2,3 or 4 wire connection).
  You can connect up to 31 sensors to one RS-485 line.

FAQ & Support

Q: Can Poseidon model 1140 store the measured sensor's values in memory?
A: No, the 1140 model only interfaces the measured data to the Ethernet network. The Poseidon model 2250 can log the measured values to a circular buffer for approx. 40 000 values in the flash memory, together with a real time synchronized over NTP.

Q: Which software should I use?
A:  Poseidon uses common protocols, this means that you can use any software, which supports for example XML, or SNMP. To make this easier, read the device's datasheet, or refer to this page: Poseidon – communication interfaces .

Q: Are there, or will there be any other sensors available?
A: Yes, we are working on more sensors, now we have a current loop convertor for 4-20 mA, 0..10V.

Q: Is there any other free software which can read and log the Poseidon data?
A:  We are working on integrating Poseidon support into some common softwares, for example used in food industry. At the end of Summer 2005 a PN Eye software will be released. This SW will read and log the values from the Poseidon and inform the operator of alarms using email, or GSM/SMS..

Q: I see that you can connect up to 40 sensors to the Poseidon, but how can I distinguish one from another?
A:  Each sensor has a unique number. If it is a 1-wire sensor, it's the last two bytes from its serial number, for RS-485 it's the bus address. This value (Sensor ID) is accessible over WWW, XML, ModBus/TCP and SNMP. If you change a 1-wire sensor for another, you need to run the autodetection again, or you will not be available to read this new sensor.

Q: What is the exact count of each type of sensors, that you can connect to Poseidon?
A: The number of sensord is limited by their type and by the type of the bus, which they are connected to. Generally, there are these limitations:
    - 10x 1-Wire sensor
    - 25x HTemp-485 sensor
    - 31x Temp-485 sensor
In one time, there can work max 42 of these sensors simultaneously.

Q: How do you secure the communication?
A: You can predefine allowed IP address range in the flash setup, the SNMP and HTTP parts can be password protected.
You can also use DIP3 to enable a mode, in which the user can work with the device, but cannot perform any configuration.

Q: The RS-485 sensors may require termination, does that mean, that I have to put a terminator after each sensor?
A: NO, you can surely find a more detailed description in any RS-485 datasheet, but simply you need to enable termination only on the last sensor of the bus.

Q: Can we use our own 1-wire sensors with the Poseidon?
A: Yes, if you use a DS18b20 or DS1822 based sensors.

Q: Can you use the Poseidon to turn on/off a PC?
A: Yes, you can use SNMP to control 2 output pins on Port2, where you can connect a relay for example.
