3 Networking 3.1 Communication protocols Both boards, the large and the small board, can utilize various communication protocols: 3.1.1 U2U (unit to unit) communications These are 2 so called Master Communications. The master communication allows the communication from board to board, as well as from board to the system display.

a) Global Bus Protocol (via Ethernet) b) Hirobus Master

There are parameters in the 3 Digits Display as well as in the large Coldfire display to preset the communication type. The Global Bus Protocol is the main protocol for iCOM Boards and iCOM Displays; Hirobus is the Protocol used by Hiromatic E and Microface E. In mixed installations one iCOM Board can be set to be the Converter between these two protocols, to make it possible to communicate between iCOM components and Microface E and Hiromatic E. See chapter 3.2.3 on page 25. 3.1.2 Internal devices communications These are 2 so called Slave Communications. The slave communication allows the board to communicate with its local devices, such as sensors, 3 Digits Display, extension boards for humidifier, navigator etc.

a) CAN Bus b) Hirobus Slave

CAN Bus and Hirobus Slave are always available in parallel, independent of the U2U communication method. 3.1.3 Monitoring Communications Both iCOM Boards provide a Hironet connection (RS485), with the same data-points as the Microface Control System. iCOM Boards identify themselves as being a Microface, therefore all Hirolink types, which are compatible to a Microface are compatible to an iCOM Board too. The iCOM Coldfire displays do not provide a monitoring connection.

ENGLISH


3.2 Unit to Unit Communication: Master Bus 3.2.1 Unit to Unit Communication: Global Bus Protocol Up to 16 iCOM Boards and 16 iCOM Displays can be connected into a private (no connection to the outside world) Ethernet network. iCOM Boards: The IP Address, the Netmask address, the Gateway address, the U2U Address and the U2U group have to be checked / set according chapter 4.1.7, The 3 Digits Display Communication Parameters on page 37, using the 3 Digits Display or an iCOM Display. iCOM Displays: The IP Address, the Netmask address, the Gateway address, the U2U Address and the U2U group have to be checked / set according table System/Network Setup on page 53. The settings can be done directly using the iCOM Display. 3.2.1.1 Connection via Crossed Ethernet Cable Two devices (2 iCOM Boards or 1 iCOM Board + 1 iCOM Display) can be connected using a crossed Ethernet cable, see Figure 23 GBP using a crossed Ethernet cable (max cable length is 50 meters). The display can be powered through CAN or through an external power supply. Note: the units are shipped out of the factory using the crossed cable connection between board and iCOM Display. If a connection via switch has to be done, this cable has to be removed and replaced with a straight-through Ethernet cable.

Groups function All units, which are interconnected inside the same LAN, will communicate to each other, if they have the same IP settings (example: 192.168.1.x). This will create problems when multiple rooms have to be connected to the same LAN, and the IP Addresses are inside the same range. There are 2 possibilities to split the rooms between each other: Physical disconnection, using 2 switches The groups function: each iCOM Board / iCOM Display has, in addition to the IP settings, also a

group number (default = 1). To split the rooms it is only necessary to set the group parameter on units which belong to room #2 to 2. Units of different groups will not communicate to each other even if connected into the same LAN the group function is like to separate the components physically. Note: the IP Addresses of all connected devices need to be unique no double numbers of IP Addresses

are allowed the U2U Addresses start with 1 within each group, in the same way as the two groups would be

physically disconnected.

3.2.2 Unit to Unit Communication: Hirobus Master Only Microfaces and Hiromatic can be connected together using the Hirobus Master. iCOM products CANNOT communicate using Hirobus Master, for mixed network see next chapter. 3.2.3 Unit to Unit Communication: mixed Hirobus and GBP (Ethernet) This type of U2U network can be established to combine iCOM Boards, iCOM Displays, Microfaces E and Hiromatics E into one common U2U network. Up to 16 control boards (mixed between iCOM Boards and Microfaces) and 16 displays (mixed between iCOM Displays and Hiromatics) can be interconnected through this GBP / Hirobus Bus-system. This Bus-system will be GBP (Ethernet) for all iCOM parts and Hirobus Master for Microfaces and Hiromatics. In the middle of these 2 Buses an iCOM control Board will play the role of a converter: its U2U setting must be set to "# [means Converter] using the 3 Digits Display or using an iCOM Display; all other iCOM components have to be set to %; all Microfaces and Hiromatics communicate through Hirobus (this is the default, non-changeable U2U protocol for such devices). See 4.1.7, The 3 Digits Display Communication Parameters on page 37. The Converter Board (besides its normal role to control the air-conditioner) communicates both in GPB and Hirobus, and translates the GBP information into Hirobus, and vice-versa. Note 1: ONLY 1 board inside a network can be set as Converter (Con); a network can consist of ONE Hirobus communication part, of ONE GBP communication part, and the Converter in the middle. Note 2: Microface and Hiromatic need to have specific Eproms with the indication LX at the end of the version number. See chapter 2.6, Spare Parts List on page 21. Note 3: The addresses of the boards can be selected as requested, important is to have a consecutive numbering, w/o holes - but there is no restriction which unit has which number depending on the selected U2U communication method. Microface E and iCOM Boards have to be addressed as described in the previous two chapters. Note 4: Hiromatics E will take the U2U Address automatically, starting from 33. iCOM Displays (which need a manual address setting) shall be numbered starting from 64 downwards, to avoid conflicts with Hiromatics. Note 5: Restrictions in cable-length remain the same as described for each protocol type in the previous two chapters (Hirobus cable total length: 300 meters, GBP Ethernet cable: max. 50 meters) 3.2.3.1 Step by step procedure for addressing the units in mixed networks

The order of the following table is according the menu-layout of the LCD. Parameter Name Description User Set ( RETURN TEMP. The temperature of the air entering the air conditioning unit.

Depending on how the unit is configured (devices and sensors installed), this temperature is measured by a Humitemp / THB or by a PTC / NTC sensor installed inside the unit in the return air flow path. For sensor installation please refer to the electrical diagrams of the unit. This temperature is used by iCOM, together with Room Temperature Setpoint, Temp. Proportional Band and Temp. Integration Factor to decide the cooling / heating status of the unit.

RETURN HUMIDITY The humidity of the air entering the air conditioning unit. The humidity is measured by a Humitemp / THB installed inside the unit in the return air flow path. For sensor installation please refer to the electrical diagrams of the unit. This humidity is used by iCOM, together with Room Humidity Setpoint, Humidity Proportional Band and Humidity Integration Factor to decide the humidification/dehumidification status of the unit.

( SUPPLY TEMP. It is the temperature of the air delivery of the unit. Available only when the corresponding sensor is installed. This value could influence the control, if Supply Limit is set.

( OUTDOOR TEMP. The temperature of the environment outside the room. It is used, together with the Return Air Temperature, to decide the Freecooling status of the unit. If multiple units are connected via LAN each unit will work with the average of the values read by all sensors. The value displayed here is this average.

( GLYCOL TEMP. The temperature of the refrigerant mixture (water or glycol and water) entering the unit. In Freecooling or Dual Fluid units, depending on the value set in DT Room-Glycol, it is only displayed or used to decide the Freecooling Status of the unit. In Freecooling units it also drives the analogue output for the Dry-Cooler. Each unit uses its own sensor for control.

" HUM COMPENSATION If enabled, the control respects the psychometric relation between temperature and humidity. Reading the actual temperature the relative humidity Setpoint will be recalculated.

&+% SUPPLY LIMIT A low limit for the Supply Air Temperature. The air conditioning unit will try to always keep the Supply Air Temperature greater than the value set in this parameter. If set to a value different from NO a NTC sensor must be installed inside the unit (or near it) in the supply air flow path. To decide its cooling status, iCOM uses the lower between a) the deviation of Return Air Temperature from Temperature Setpoint and b) the deviation of Supply Air Temperature from Supply Air Setpoint. Note: Supply Limit is capable to reduce the opening of dampers or valves, but will never stop a compressor. (Exception: the 2nd compressor in a twin compressor unit will not start if the supply temperature is already too low, but it will not be stopped if it becomes too low once started).

T-PROPORTIONAL BAND T-INTEGRATION FACTOR

Normally best results will be reached if the 'AUTOSET' is enabled. The Proportional Band is divided in two equal parts, one part for cooling, and one part for heating (hysteresis). Inside this hysteresis there are the different components (compressors, heaters), which share the width of the hysteresis. If Teamwork Mode 1 is selected, the P-Band belongs to the whole system. NOTE: Too small P-Band will cause the bad control quality (hunting). Integration Factor: If set to any value, the PI control is enabled. The integration factor doubles the actual, real deviation from the Setpoint within the selected time. This will force cooling/heating to add more steps to reach the Setpoint. To be used if P-Band must be wide because of bigger number of units connected, and working in Teamwork 1.

(COOLING 2): Signal increases to 10V within the compressor 2 hysteresis. && (SUPERSAVER): Output for Setpoint- shifting of Superchillers / Matrix units. (ALARMBOARD): Signal for Alarm board * (METRIC ROOM): Drive signal for Hotgas reheating in 'Constant-like' units. NOTE: Compressor will not stop on Setpoint, but 25% of p-band lower, with a delay of 20 minutes. "# (I-Variex): Signal for Condenser Fans speed control & (D-Scroll): Signal for Digital Scroll compressor management. NOTE: it is enough to set one of the available analog outputs as D-Scroll to active the digital scroll compressor management; in this case the related output is automatically used to manage the condenser fan speed as for I-Variex function; the digital scroll compressor capacity is done by the digital output 12 (P35 1/5). The I-Variex and D-Scroll functions becomes independent as soon as one output is set as D-Scroll and another one is set as I-Variex; in this case the digital scroll compressor capacity is managed by the related analog output set as D-Scroll and not by the digital output. ": Like the cooling output, but inverted: 100% at the setpoint, 0% at full cooling.

" LOW AIRFLOW AT Use 'AUTOSET AIRFLOW' to set. Depending on the value assigned to this parameter, iCOM will generate warning or alarm when the voltage generated by airflow sensor is lower than the threshold set. If a differential pressure switch is used, & (SWI) has to be set.

& AUTOSET AIRFLOW Stop the unit first. Set parameter to 'YES'. The unit will start the fan for 30 seconds, and then wait 30 seconds with fan off. After that the value will be set. If a warning appears, there was no reaction from the airflow device.

" AIRFLOW VALUE Read only analogue value (percentage) that informs about the airflow speed inside the unit. This value can be taken into account when setting the Low Airflow At parameter.

FAN FAILURE Depending on the value assigned to this parameter, iCOM will stop humidity control and heating only when set to % (Warning) or will completely stop the Unit when set to % (Alarm), when the airflow value is lower than the threshold setting.

% LOW.PRES.AL.DELAY The time delay (in minutes) after a start of the compressor(s) in which the occurrence of a low pressure alarm is ignored. After this time the low pressure alarm is delayed of approximately 10 seconds.

" COMPRESSOR DELAY The compressor is activated after the delay set; this function is used on those units equipped with interceptor water valve.

value set in this parameter. If set to a value different from NO a NTC sensor must be installed inside the unit (or near it) in the supply air flow path. To decide its cooling status, iCOM uses the lower between a) the deviation of Return Air Temperature from Temperature Setpoint and b) the deviation of Supply Air Temperature from Supply Air Setpoint. Note: Supply Limit is capable to reduce the opening of dampers or valves, but will never stop a compressor. (Exception: the 2nd compressor in a twin compressor unit will not start if the supply temperature is already too low, but it will not be stopped if it becomes too low once started).
