Operator’s Workstation User’s Manual 6-1 Chapter 6 Displaying Drawings Introduction This chapter explains how to display the dynamic drawings that represent the networks, PC groups, and systems in your facility. This section explains how to: • display drawings Note: Micrografx Designer and Draw software are not supported at Metasys Release 11.00 or later. © November 1, 2001 Johnson Controls, Inc.

Figure 6-1 shows a System summary with an air handling unit as a textual list of objects. Figure 6-2 shows a system drawing of the same system with graphical symbols representing the objects.

Analog Output and Binary Input and Output objects update whenever there is a change-of-state. Critical Alarm messages appear over the drawings, immediately informing operators of alarms. Operator Workstation User’s Manual 6-3 Handles All Windows applications use up or consume Windows handles. Every application uses handles, and 8,192 handles are available, including: Windows operating system, Metasys software, and Metasys graphics. The number of handles that each application uses is dependent on the contents of the application. For example, an average graphic uses around 500 Windows handles, although it may be more or less dependent on the complexity of the drawing. A graphic with a lot of objects uses more handles than a graphic with just a few objects. Do not open several complex graphics that use a large number of objects at one time. If you use up all of the available handles, Windows operating system generates a General Protection Fault and you must reboot the system. 6-4 Operator Workstation User’s Manual Detailed Procedures Displaying Drawings To display drawings: 1. On the View menu, click Show as Drawing. 2. Select the desired system. 3. On the GoTo menu, click Selected Item. The system appears as a drawing, displaying the current values and states of all bound objects. Note: If the drawing has not been modified, and only the default symbols and default graphic binding settings are in effect, it appears complete.
