Industrial Bus sensors (RS-485)

Industrial bus for connecting sensors over longer distances

Connect the sensors before powering up the unit.

Sensors can be daisy-chained, or connected to a virtual star using

the “S-Hub” unit.

Terminate the RS485 line with a 120 Ω to 470 Ω terminator. Some

sensors contain a built-in, jumper- or DIP-controlled terminator. See
the sensor manual.

Check or set the sensor address. Each sensor on the RS-485 bus must have an unique

address. The address (ID) is expressed as a letter (A..Z / a..z) or a number (65..122). The
numbers correspond to the ASCII codes of the letters, A=65, Z=90, a=97, z=122.
For details about address configuration, see the sensor manual.

If you change the sensor topology, the sensors must be auto-detected again.

(Web interface > Flash Setup > Sensor Setup > Autodetect Sensors)

Sensors are shipped with non-conflicting addresses whenever possible. The preconfigured address
is written on the label.

Note: A particular sensor is identified by its RS-485 address. Sensors with the same

address can be swapped without the need for a new detection.

• For details about connecting sensors, see the description of the interfaces.

• For more information about connecting sensors and wiring lengths, see the

detailed manual for the Poseidon line of products.

Common features of the Poseidon product line

Displayed readings

The Poseidon unit displays current readings from all connected sensors.

Dry contact inputs are scanned approximately every 200ms.

Values from all sensors on both buses (RS-485 and 1W bus) are read in a single loop that

repeats once per second; however, the actual time needed to read the sensors may vary
from 1 to 30 seconds

All values are in the “integer/10” format, range is ±999.9.

A value of 999.9 is out of range for all supported sensors and indicates that the sensor was

not found.

If you have disconnected or replaced a sensor, run sensor autodetection, or remove

the sensor from the list.

When the Poseidon unit is overloaded with network requests (as is sometimes the

case, for example, with our public online demo), -999.9 can sometimes appear even
though the sensor works properly. This is due to limited computing performance of the
unit. Try to reduce the load.

Units are assigned to values automatically according to the detected sensor type. Supported

units include:

Temperature: °C, °K, °F

(please note that Safe Range thresholds can be set in °C only)

Humidity: %RH

Voltage: V, current: A or mA

Other units: %, etc...

Input / sensor in alarm state

Alarm state can be set independently for every input (contact) / sensor.

For a sensor, “Alarm” occurs whenever the reading is outside of the specified Safe Range,

as long as alarm alerting is enabled for at least one notification method (SNMP / e-mail &
SMS).

Response to a sensor being disconnected

-999.9 is displayed

The value evaluates as an “Alarm” (reading out of the specified Safe Range). If alarm

alerting is enabled for the given sensor, e-mail or SNMP trap is sent.

• For more information about data formats, variable identification and the SDK,

see the detailed manual for Poseidon product line.

14 / 54

Sensor hysteresis

The Hysteresis setting defines a tolerance band for alarm alerts. This feature prevents multiple
alarm alerts if the reading oscillates around the specified threshold. See the graph for an
explanation.

Without a hysteresis of 5°C, the alarm raised at point 8 would end at point 9. With the hysteresis
function, the alarm continues until the temperature rises above the tolerance band (point 10), that is,
5°C + (-15°C) = -10°C.

Hysteresis = 5°C: The unit sends 3 e-mails (SMS)

Alarm at points 0..4, 8..10, 12 and beyond

No hysteresis (0°C): The unit sends 8 e-mails (SMS)

Alarm at points 0..1, 2..3, 8..9, 12..13, 14 and beyond

• For more information about data formats, variable identification and the SDK,

Detailed device description

Power connector

The usual DC plug – 2,5mm coaxial barrel
connector – is used to connect the power.
Negative terminal is connected to the outer body of the plug.

Ethernet

Ethernet network connects via the standard RJ45 jack next to the power
connector. Use a Twisted Pair (TP) patch cable to connect to a switch, or a
cross-over cable to connect directly to a PC.

The device has a 10 Mbps Ethernet interface => it only works in 10 Mbps or 10/100 Mbps networks.

Note: The device cannot be directly connected to a 100 Mbps-only network. If you need to

connect it to a 100 Mbps (or faster) network, use a 10/100 Mbps Ethernet switch.

MAC address

MAC address is a unique number identifying the device. It is printed on the label at the bottom side of
the unit. It consists of six hexadecimal number pairs, the first three pairs are always 00:0A:59.

With the MAC address, you can distinguish individual devices in the UDP setup utility when assigning
IP addresses.

Configuration with DIP switches

DIP switches control the following functions. If you
change the settings, it is recommended to reset the
device by disconnecting and reconnecting the power.

Factory default configuration is:
DIP1=Off, DIP2=Off, DIP3=Off, DIP4=Off.

DIP SWITCH configuration

+ DIP1 – RS-232 Setup

ON = RS-232 Setup mode (RS-232 mode only), OFF = Normal mode, network active

LOAD DEFAULTS: Toggle the switch 3 times within 5 seconds after powering up.

Port 3 DB9M - RS-232

The interface is intended for setting up the device (RS-232
Setup when DIP1=ON) and for updating the firmware.

The DTR and RTS outputs can be controlled from the Flash
setup interface, tied to an alarm state, or controlled over the
network.

Voltages corresponding to logic levels on these outputs:

RTS

0 (Off) = -10V (-12..-6V)

1 (On) = +10V (6..12V)

DTR

0 (Off) = 0V

1 (On) = +10V (6..12V)

States of outputs after device restart: RTS = Off (-10V), DTR = Off (0V).

Using the RTS and DTR outputs

Port 3 complies with the RS-232 specification. If needed, the P1250 RC converter (designed for
connecting two 12VDC rated relays to Poseidon 1250 over RS-232) can be used to connect two
external relays. The converter applies approximately 10V to the relay coil, making it possible to
control 9VDC or 12VDC rated relays.

P1250 RC (Relay Cable) - ordering No. 600 244

Relay coils connect directly to a small terminal block. Polarity is shown on

Port 1 (RJ11) 1-Wire bus / 1-Wire UNI

1W or 1-Wire bus is a bus invented by Dallas Semiconductor and
designed to connect several sensors over a short wiring. The bus
carries power and a single data wire; it is not suitable for long
distances or environments with EMC interference.

We recommend to keep the total wiring length under 10m, although
functionality has been achieved over tens to hundreds of meters in
experimental settings.

The manufacturer guarantees correct bus operation under the
following conditions:

Up to 10m total wiring length when using the star topology. (T-Box is used.)
Up to 30m total wiring length when using the daisy-chain topology.

(No T-Box is used, units are daisy-chained using two RJ11 jacks on the sensors)

For longer than specified wirings, error-free operation is not guaranteed and depends on the
cabling, topology and environment.

Maximum wiring length: 10m / 30m in total

Supported sensors: Temperature, humidity sensors (see the overview of available sensors)

Number of sensors on the bus: Up to 10 sensors

Power to sensors: 5V/50mA available at the RJ12 jack

Sensor power consumption: Power supplied over the bus is sufficient for all connected

sensors

Communication cable: 4-wire telephone cable (2-wire in special circumstances)

Alarm settings: Checking the reading against its Safe Range, configuration over WWW –

Poseidon Flash setup

Polling period: 800ms to 10s (depending on the number of connected sensors, 10s for 41

sensors)

Sensor address assignment: Automatic, each sensor has a unique address

Range of sensor IDs: Sensors use IDS from 257 to 65535

Sensor names: Sensors can be independently named using up to 12 characters, the name is

tied to the sensor ID

Disconnected sensor detection: Yes, disconnected sensors read as “-999.9”

Alarm if sensor is disconnected: If the sensor is set to alarm whenever its reading is outside

of the safe range, disconnection triggers the alarm

Remember: All 1W bus sensors have their unique serial numbers. These are stored with

sensor names during autodetection and expressed using the sensor IDs. If you
change the sensors on the bus, you must re-run Autodetection in the Flash
SETUP.

by the bus is sufficient for up to 3 external sensors, an S-Hub can
be added to power more sensors

Communication cable: UTP, in some cases 4-wire phone cable

Alarm settings: Checking the reading against its Safe Range,

configuration in Poseidon Flash setup

Polling period: 800 ms to 10 s (depending on the number of sensors, 10 seconds for 41

sensors)

Sensor address assignment: Manual, each sensor must have a unique address (see

sensor manual)

Range of sensor IDs: Sensors use IDs from 48 to 122, the address corresponds to the

ASCII code of 0..9, A..Z, a..z characters.

Disconnected sensor detection: Yes, disconnected sensors read as “-999.9”

Alarm if sensor is disconnected: If the sensor is set to alarm whenever its reading is

outside of the safe range, disconnection triggers the alarm

General RS-485 characteristics

Maximum wiring length 1000 m

Up to 32 devices on the bus (Poseidon unit + 31 sensors)

High resistance to noise in industrial environments

Daisy chain topology is necessary (as opposed to star topology)

Each device must have a unique address

Wire polarity must be respected

Line must be terminated at the beginning and at the end

Termination

The RS-485 bus must be terminated at its end. The following options are available:

Internal jumper on certain sensors (jumper named TERM or TERMINATOR) – for example

Temp-485 or HTemp-485

B-Cable adaptor with “LAST” configuration selected using the switches

External resistor to terminate the bus at the “last” sensor, if the sensor has no jumpers or

DIP switches (Temp-485-Pt100). Connect the resistor between the A and B terminals of the
last sensor.
The resistance of this resistor should be 120Ω, For short wirings, 470Ω can be used to
reduce the current consumption of the sensors.

Note: A disadvantage is that it is necessary to have a wiring topology with a single

beginning and a single terminated end, as opposed to the popular star topology with

a single interconnection point.

Special accessories for the RS-485 bus

B-Cable - RJ45 / 4-wire connection

The B-Cable module is an adapter that converts a RJ45 jack
connection to a block of 4 terminals A,B,+,–.

Some of the available RS-485 sensors already have a RJ45
jack; however, some only have 4 terminals labeled A,B,+,- .
Such sensors can be connected to the Poseidon 1250 unit or to
an S-Hub using either a TP cable (4 or 6 wires) or the B-Cable
module.

The 4-wire connection

length should not exceed
20cm.

Sensor position on the RS-

485 bus (MIDDLE / LAST)
is selected with jumpers;
see the picture for details.

Sensor RJ45 MIDDLE cable

RS-485 cable, 0.5m, RJ45/4 pins. Connects
4 terminals (A, B, +, - ) to a RJ45 modular jack
(uses 3 pairs).

This cable is used to connect all sensors
except for the last one in the chain.
Sensors connected with this table must not

terminate the RS-485 bus.

Sensor RJ45 LAST cable

RS-485 cable, 0.5m, RJ45/4 pins. Connects
4 terminals (A, B, +, - ) to a RJ45 modular
jack (2 pairs only).

This cable is used to connect the last sensor
in the chain.

The sensor connected with this cable MUST
TERMINATE the RS-485 bus in one of the
following ways:

External 120Ω resistor

Jumper or DIP switch at the sensor set to TERM=ON

S-Hub – 8x RJ45 TP hub
The S-Hub unit with one input and 8 output ports is used
to connect up to eight RS-485 sensors with TP cables.

Makes it possible to connect sensors in a star

topology (sensors must be connected using TP
cables)

Simpler and faster connection of sensors

Makes expanding an installation easier

Simplifies supplying power to the sensors – a

standard power adapter connects directly to the S-Hub unit

Note: It is possible to mix the star / daisy-chain topologies with S-Hub, see the

examples in the following chapter.

Industrial Bus (RS-485) wiring example

The bus leads via a 4-wire connection (two twisted pairs) from a Poseidon 1250 unit to two

daisy-chained sensors, Temp-485 and HTemp-485.

An S-Hub unit is daisy-chained via the RJ45 jack to the second HTemp-485 sensor using a

4-wire connection. The brown pair carries power, the blue pair is used for data.

Temp-485 and HTemp-485 sensors are connected to S-Hub connectors 1 through 3 using

6-wire connections (brown pair for power, blue pair leads the bus to the device, green pair
back from the device).

Connector 4 of the first S-Hub unit is used to connect a Spider converter with a patch cable.

The Spider unit is used to connect three Temp-1Wire 10m temperature sensors and one
door contact (the contact is connected to the blue pair of the RJ45).

Temp-485 and HTemp-485 sensors are connected to S-Hub connectors 1 through 3 using

6-wire connections (brown pair for power, blue pair leads the bus to the device, green pair
back from the device).

Connector 4 connects a Temp-485 sensor over a 4-wire connection (brown pair to power the

sensor, blue pair for the A/B signals of the bus).

The Temp-485 sensor is configured to terminate the bus using the TERM jumper.
