1.2 Communication interfaces

• Digital data link RS485 2 wire

Protocoles Modbus-JbusFormat of the data: integer and double integerExclusive transmission format: 1 start bit, 8 parityless data bits,1 stop bitSlave number between 1 and 255Baud rate between 1200 and 19200 BaudsOptional time delay before the response of 75ms.

Table of the Modbus addresses and the used functions: see annexe page 9

The digital data link is of the type «slave» in standard or «master» if option «M».In slave mode the MODBUS writing is possible with the option Y.

A set of 10 µswitches «SW201» on one side of the housing allows to select the end of line resistors (RT) and polarization resistors (RP) depending on the installation. (The end of line resistors allow to reduce the parasitic reflec-tions generated in a long line with high speed. They are not necessary if the environment is free from disturbances and the distance < 1000 m.)

1.3 Functions

¦ Interface for the distribution of the power supply to the TPIs’s

The TPIs M allows to distribute the power supply (24Vdc 30%) on the 2 supply terminals of the connection footings of the TPIs’s of the network.The max. current drawn by the network must be < 3.5A.A circuit breaker or an exernal fuse adapted to the drawn current is recommen-ded (to be placed between the used auxiliary power supply and the TPIs M).

The maximum number of TPIs’s inside the network managed by the TPIs M is limited to 50.

¦ Supervisor and concentrator of measures for TPIs’s

The TPIs M is the «master» of a local network made up of maximum 50 TPIs’s (always slave).The response time of the screening is 1 ms per measure.The measures and the «inputs / outputs» of the network can be accessed via the digital data link (RS485 / MODBUS).

¦ 1 isolated logic input

Ø Available functions:

This logic input can be associated with any TPIs of the network.

Type Active Inactive Max.voltage

Max. drawn current

Standard:potential free con-tact, or transistor

< 200Ω >1kΩ 8V 8mA

Option:T24: 24V ±30% If > 16V Si < 2V 32V 1.1mA

Option:T5: 5V TTL If > 2V Si < 0,8V 6V 1.2mA

Ø Electrical features:

• Operating mode:1 operating mode possible only for the logic input:

Mode level: the activation of the logic input sends a status «1» on the concerned measure, the de-activation sends a status «0».

¦ 1 relay output of the type «potential free contact»

This contact of the type «NO» of 6A/250Vac or 24Vdc on resistive load can be associated with any TPIs of the network.

Max. response time of the contact ......... 10ms + [1ms x number of used measures of the network]

Ø Relays control = direct control

• Choice of the coil status if associated logic input «active».

Ø Relays control = setpoint

• Choice of the status of the LED associated with the relay:The status of the LED is the image of the alarm status:LED lit = on alarmLED off = off alarm

• Hysteresis of the alarm:Programmable from 0 to 100% of the setpoint value.The hysteresis is activated on switching to the status «off alarm».

p5

• Mode setpoint:1 setpoint configurable over the whole input range

• Mode window:2 setpoints configurable over the whole input range

• Type of safety:

HIGH:The coil of the relay is powered if:measure > setpoint (in mode setpoint)measure < setpoint 1 or measure > setpoint 2 (in mode window)

LOW:The coil of the relay is powered if:measure < setpoint (in mode setpoint)setpoint 1 < measure < setpoint 2 (in mode window)

• Time delay on the alarm:The relay time delay can be set from 0 to 25 seconds, in 0.1s. increments.It is active both on switching and switching off.

• Recording of the alarm:Allows to record the alarm after a setpoint has been passed. When the measure reverts below the alarm setpoint, the relay remains ON and the LED blinks to warn the user that the setpoint has been passed (reset to 0 by programming).

• Weight and width of the pulse programmable if piloted by an integrating converter TPIs 61 or TPIs 261.

• Self-diagnosis

• Sensor break

3. CONFIGURATION OF A LOCAL NETWORK OF TPIs’s

First start by launching the configuration software SlimSet.The purpose is to define your network using the software.

1) First connect the TPIs M to the PC.

Click on «communication with the devices» and then on «add the connected device to the architecture». Then give its position in the architecture.Now click on «communication through the master» and then «add or remove some devices».

The software will then take up all the instruments present on the bus and read their configuration one by one.

For each instrument detected, the SlimSet will request its position on the ar-chitecture. This position can be determined by a specific blinking of the green led of the concerned instrument (morse code blinking: twice on, once off). This position will be saved inside the TPIs M configuration and restored at each configuration reading.

3) Then programme each of the instruments, as well as the links between ins-truments:for each of the outputs of the output modules (TPIs 4R, TPIs 2A/4A ...) you must define the converter associated with this output, as well as the measure associated with this output.

4) Then programme on the TPIs M the measures to be braught back(collected measures).

The network must always be validated after adding / removing an instrument and after the modification of all the links between instruments.

5) Then connect yourself on the TPIs M and click on «communication with the devices» and on «communication through the master» and then on «send the configuration to all devices».

6) Then connect yourself on the TPIs M and click on «validate network».This will record the configuration of the bus in order to point out any error (loss of a module for example).

The TPIs M can manage up to 100 different measures, with a processing time of 1 ms per measure. In this case the response time of the network will be 100ms.

7) Measure of the TPIs M:

The TPIs M proposes a measure which is the general diagnosis of the network and 50 internal registers, accessible in writing (option Y).

The orange led «Master» of the TPIs M blinks very fast to indicate a correct communication, it blinks less fast (0.1s / 0.1.s) to indicate a communication error and it stays fixed if there is no communication with the TPIs’s.

5. ANNEXE 2: CALCULATIONS (OPTION C)

With the option C you can have on the TPIs M 10 calculation formulas, pro-grammable in a dynamic way, using operators, pre-defined functions, collected measures, external registers of the TPIs M and 16 programmable constants. You can create groups of measures in order to perform operations directly on the whole group.These 10 results can be directly associated with all the instruments of the network.

Example of formula:if ((Measure 1 ≥ constant 0) AND (Measure 4 = True)) then (True)

Constant 0 = 525°Measure 1 = Measure of the temperature of a furnaceMeasure 4 = logic input

If the temperature of the furnace is ≥ 525° and if the logic input is active then the result of the formula is true.
