6.0 Using the C3-3 Display to View and Configure the Centurion Controller Settings The Murphy C3-3 Display module is a highly integrated operator interface specially programmed to complement and support Centurion controller. The primary purpose of C3-3 Display is to display operational and configuration parameters and provide access to modify the configuration parameters stored in the Centurion controller. 6.
HOME HOME Operating Status Screen Allows the user to get to the first line of the current screen, or if pressed again, to get to the default operating status screen. Set Up Screen Allows the user to get to the first line of the current screen Edit Screen No associated action. ESC/ACK ESC ACK Operating Status Screen Acknowledge the active message/alarm that is currently displayed in the Alarm Banner. Acknowledges all active messages and alarms displayed in the Active Alarm Screen.

6.1.2 Display Context The graphic LCD displays are organized around operating status screens and setup screens. The actual number of status screens will be related to the total number of end devices configured for the controller. In either screen set, ten (10) lines are visible at a time; with up and down arrow characters indicating more lines are available on the page. Also, for both screen sets, navigation between screens is accomplished by pressing the left or right arrow keys.
6.2 Operational Screens In addition to the set up screens reviewed in Section 7.3, the C3-3 Display offers a number of operational displays. On the Operating Status screens, the two bottom lines display the state, hours, mode and active timer status. This information is key to understanding the “status” of the controller. Mode refers to the Operating Mode of the controller and can be LOCAL or REMOTE.

7.2.3 Downloading Configurations Via MConfigPro Software The Centurion makes it easy for a user to download a configuration through the MConfigPro software. 1. From the Options menu of the MConfigPro software, choose the Options tab to identify the ports that the users PC can detect, and select the appropriate port that the user’s PC will use to communicate with the C3-3 Display or Centurion controller. Set the individual port parameters. 2.
7.2.6 Error Messages There may be occasion when an invalid configuration error might display because the configuration between the Centurion controller and its devices are out of synch--that is to say the checksums do not match. In fact, the invalid configuration screen will appear briefly after downloading configurations until comparisons are made. Field testers may decide to ignore the message, if the user knows that the changes are not critical.
7.3 Modbus Protocol The Centurion configurable controller was programmed with the Modbus protocol which is a system is based on a “master” and “slave” relationship. With Modbus protocol, the master and slave are able to continue to communicate with each other through defined messages over a variety of network types. The master initiates the queries or commands, and the slave responds to the query with a message or takes action based on the query.
8.0 Glossary Analog Input Terminals A18 to A29 are analog inputs on the C3-1 Centurion main I/O module. Accepts voltage signals within the range of (0 to 5) VDC or (4 to 20) mA and are compared to controller set points or events. Boot loader Means by which the Centurion controller communicates with C3-3 Display and MConfigPro to receive and transfer new or updated configurations and firmware; and ensure data and configuration synchronization.
9.0 Appendices 9.1 Back Panel LED Description There are a total of seven (7) LED indicators on the back panel, labeled as follows: (Port 1) TX – Turned on while Port 1 is transmitting data. RX – Turned on while Port 1 is receiving data. (Port 2) TX – Turned on while Port 2 is transmitting data. RX – Turned on while Port 2 is receiving data. USB LINK – Turns on while there is a USB connection to a computer.
