Page 4 Preface The Andover Controls Infinity CX Programmer’s Guide is a two vol- ume set. The volumes present the following: • Volume 1—Getting Started Programming • Volume 2—Advanced Programming/Access Control If you are using the control system for HVAC, you should proceed through this manual sequentially.
Page 5 Whether you use this system for HVAC or for access control, you should already have installed your hardware before you attempt to set up the Infinity CX system. If you do not know how to arrange your network to set up your hardware, refer to the EnergyNet and Infinet Configuration Guide.
Page 6 Chapter 21 in this volume. This volume also covers creating your own functions, setting up and using data files, and programming DCX 250, modems on Infinity CX and CMX controllers, expansion modules, and more. It also has a special chapter on debugging techniques.

Page 10 You may want to label your map so it reflects the actual layout of the controller system. Each Infinity CX controller on that map can have one or more input output units (IOUs). Each IOU has a number the con- troller identifies it by.

Page 12 We refer to all these sensors and transmitters as input and out- put points. Input and output points are Infinity’s way of interacting with the environment. An input point is constantly receiving information about, for instance, the temperature in a room. While that temperature remains within a set range (say 68 to 72), the controller takes no action.
Page 13 Finding Points on IOUs You might want to make copies of the drawings on the next few pages, one for each Infinity CX 9000 IOU and each Infinet controller on the network. The drawings show the input and output points and the nu- meric labels supplied at by Andover Controls.

Page 553 Chapter 15 Programming the DCX Screen Your Infinity CX 9000 controller may have a 4.9 × 4.2 inch liquid crystal display (LCD) screen in the upper right front door of the cabinet. This screen is the DCX 250. You may also have a DCX 250 located elsewhere in the building, connected to the control system via Infinet.

Page 558 Determining Location on the Screen To give the location of the button on the screen, you tell Infinity the position of the lower left corner of the button, then the upper right corner. How? Picture the screen covered by hundreds of tiny dots.
Page 559 DCX Screen Telling Infinity to Display the Control To display a button control (Control Style 1) in the approxi- mate center of the screen, you enter the information you have collected with the CONTROL keyword. The format for the CONTROL keyword is as follows:...
Page 560 Try altering the left, bottom, right, and top values to see how they change the shape and size of the button. This control style (1) and Control Style 2 must be a minimum (in line points) of 40 wide by 25 high. 15-8 Infinity Controller Programmer’s Guide Technical Manuals Online! - http://www.tech-man.com...
Page 561 For control styles 1 and 2, you cannot give a frame style (see end of Appendix C), because the frame is automatically included with the control. If you give a frame style, Infinity ignores it. Other Arguments for CONTROL Notice that the direction, bottom and top of scale, tickmarks,...
Page 562 The control is then horizontally centered within the space you have defined. If the control cannot display in the space you give, Infinity dis- ables the file; you can then find the error message in the File Configuration window.
Page 563 “cells” or “touch cells.” Figure 15-6 (on the next page) shows where the cells are on the screen. Infinity can sense when you have touched one of these cells. You must position the control so that it can use these cells.
Page 564 The rule applies as long as you want the operator to have the option of setting the control. If you set that argument to FALSE, the arrows do not appear. 15-12 Infinity Controller Programmer’s Guide Technical Manuals Online! - http://www.tech-man.com...
Page 565 For any button or switch control (Control Styles 1, 2, 3, 4, 5) you Assume ON/OFF do not have to set a top and bottom of scale. Infinity automatical- ly sets them to ON and OFF for a digital point or to the two values of a digital attribute, such as ENABLED and DISABLED for STATE.
Page 566 DCX Screen If you do not give a top and bottom of scale, Infinity assumes ON and OFF or other digital values. For Control Styles 8, 9, and 10, you must give a top and bottom of scale unless you assign it to a digital point or attribute.
Page 567 The point the knob controls is on the FLOOR1 Infinity CX and the ROOM2 Infinet controller. You want the knob to be in frame style 3 and to title the knob with the name of the point, AIRFLOW.
Page 568 DCX Screen This style control is always one size. When you give the left, Infinity Automatically bottom, top, and right, Infinity automatically centers the con- Sizes Knob trol in the area you designate, as long as the center of the knob is at least 30 line points away from any edge of the screen.

Page 575 The 60 is the bottom of scale, the 90 the top. Figure 15-14. Display of Value Bar with Raised Arrow Buttons (Control Style 9) Setpt Room 2 72.5 Infinity Controller Programmer’s Guide 15-23 Technical Manuals Online! - http://www.tech-man.com...
Page 576 The 60 is the number of steps (one for every 0.5 degree between 60 and 90). If you do not include a number of steps, Infinity as- sumes 1 step, the number of steps for a digital control. But one step is not useful in this situation, because the one step would go from the bottom of scale to the top and vice versa.
Page 577 DCX Screen When you alter the area for a this control, Infinity sizes its height and width fit the area. Figure 15-16 shows how the slider control appears in the DCX 250 screen. Compare this to the appearance of the sample Control Style 12 in Appendix C.
