IQ23x Data Sheet Functionality The IQ Controller’s functionality can be divided into three sections, strategy, firmware, and hardware. Strategy The strategy processes inputs according to a set of instructions and then outputs signals which can be used to control plant. Configuration: The IQ23x uses the standard IQ configuration mode which enables configuration by way of the network, or the supervisor port. SET can be used to create a strategy data file (.IQ2) which can then be downloaded to the controller and subsequently uploaded for backup purposes if connected to the controller directly, by way of the network or by way of a modem. A strategy data file from an IQ1xx controller (.IQF) can be downloaded to an IQ23x and will require modification as explained in the compatibility section Modules: The strategy consists of a number of individual functional blocks known as configuration modules. These blocks can be linked in various combinations to enable plant to be controlled in accordance with the building’s requirements. The table lists the different types of configuration modules and the number of each type available with IQ23x.

The IQ23x contains the normal IQ2 features as described in IQ Configuration Manual Addendum: Engineers Journal (J), I/O Summary (i/o) Loader Issue (R(c),’c’ lower case), Serial Number (R(s), ‘s’ lower case), Supply Frequency Option, Enhanced Logging, Module position, and Strategy Cleardown. Differences between the modules covered in the manuals and the IQ23x’s modules are covered below. Address Module It has two additional items described below: default PIN disable: This increases the controller security by disabling the default PIN. It is accessed using the character “d”, setting d=1 will disable the default PIN. It may be enabled by setting d=0 (as long as a valid PIN is used). This change requires a PIN with level 99. If the default PIN is disabled and the PIN settings are unknown (e.g PINs forgotten or after battery replacement), the unit can be restored by clearing the strategy using the address/baud rate switch zero reset and then downloading the strategy. Firmware Communications: When operating as part of a Building Management System, the IQ23x will be connected to other devices by way of the Trend Network. This means that information within the IQ23x can be accessed using one of the Trend supervisor programs, or passed to other Trend IQ controllers using inter‐controller communications, enabling the sharing of information across the whole system. When connected to the network the controller can use up to 2 different addresses. One address is for the controller itself, the second is optional, and is for the supervisor port (locally connected supervisor). The controller’s address is set by a switch, and the supervisor port address is set up in the strategy configuration (address module). Hardware Unit: The IQ23x is supplied in a metal enclosure. It has 4 mounting points which are on the same centres as the IQ111+ and IQ131+; they are also the same as those provided by the IQ111 or IQ131 using the mounting bars. Its footprint is smaller than IQ111 or IQ131, and the same as the IQ111 or IQ131 with their mounting bars, but it is 13 mm deeper Connectors: Two part connectors are used throughout to facilitate wiring. An earth flange is provided for screen termination with a special M3 earth stud close to the network connection, and there are cleats for cable restraint. Power: 230 Vac 50/60 Hz. Note that this unit must be earthed (grounded) via the Earth terminal of the IEC connector. Fusing: The controller has no replaceable fuses; protection is provided by means of a self-resetting thermally protected transformer. Indicators: LED indicators for receive and transmit network current flow (RX, TX) and network OK ( ), also for all I/O channels, power ( ), and fail ( ). See specification section for details. Network: The network terminals facilitate connection of 4 wire cables. The standard Trend node features are included (TX, RX, and network OK, , indicators, bypass relay, and network alarm generation). There is also the facility for connection of a supervisor or network display panel to the network by way of the controller without the need for an additional node controller. Internal Node: A node controller card may be fitted inside the unit either as a pre-fitted option, or post-fitted using the appropriate cables. There is a two pin polarised plug to supply 24 Vdc to the node and a four pin polarised plug which provides a network connection. There is a set of two pairs of pins adjacent to the network plug which are normally shorted by two links; these must be removed when the node is connected. For an integral node controller to operate the external network must be connected, or the external network terminals must be linked (TX to RX). sUperv port addr: This operates as described in the IQ Configuration manual addendum with the additional feature that if the address is set to 120, the supervisor port will be disabled. This gives increased security. The port can be enabled by setting the address to another value by configuration or text comms over the network. Byte 506, Bit 1 This bit now has the fixed function of ‘IQ1 series simulation of universal input action’ (see Compatibility section, Firmware). 2 IQ23x Series Controllers Data Sheet TA200538 Issue 2, 18-Jan-2012
Data Sheet IQ23x Hardware (continued) A node is post-fitted using KIT/NODE/IQ23x. This provides mounting plates, pillars, screws, and cables to enable connection of the current nodes (TMN, CNC2, PNC2, INC2, LINC, and XN28); the node card is ordered separately. There is a 25 way D type knockout on the upper panel for RS232 connection to the node, and a circular knockout for 14.25 mm grommet for internetwork, PSTN, ISDN, or Lon cables. The two links on each input channel must be correctly positioned to set up the type of input required. 6 loop powered , 8 loop powered 1 View on top of board mounting plate network connector J2 J47 J48 supply connector network links R+T+T-R- externally powered , N 1N externally powered Address/Baud rate switch: The address on the Lan is set by poles 1 to 7 in range 1, 4 to 9, 11 to 119 and must be unique on the Lan. The baud rate is set by poles 8 to 10 in the range 1k2, 4k8, 9k6, 19k2 and must match the other nodes on the Lan. The 4k8 baud rate is selected by setting all three poles to zero. The address/baud rate switch may also be used to perform a strategy cleardown; this is done by setting all the address/baud rate poles to zero before power up (see Installation Instructions, TG200539 sheet 3 and IQ Configuration Manual Addendum). For this reason the address should normally be set non-zero. Analogue Voltage Outputs 8 (IQ231: channels 1 to 8; IQ233: channels 1 to 12) Link Headers A range of link headers is available to enable the input channels to accept a wider range of inputs: LKE/5V: Provides 5V, 20 mA supply 13 ! N Battery Backup: Details about the strategy configuration, time and date, and logged data are stored in RAM. A plug‐in lithium cell provides power to maintain the data in the event of power failure, or the controller being switched off. & 24 Vdc Auxiliary Supply: The IQ23x has a 24 Vdc auxiliary 500 mA supply protected by a self-resetting passive thermal device. It is available from two terminals on the back of the unit for relay modules, interfaces etc. and is completely separate from other supplies.
