Chapter A–B 1 Overview Chapter Objectives This chapter is an overview of Powermonitor Software system components and capabilities. Detailed information regarding system requirements can be found in Chapter 2. Introduction Powermonitor Software is a software package designed to remotely display the data measured by the Powermonitor. The Powermonitor Software is capable of configuring and controlling all aspects of remote devices.
Chapter 1 Overview The Powermonitor Software data files format allows the user to apply standard database application programs such as LotusTM or others to produce system reports such as: a. load trending b. trouble analysis c. cost analysis d. cost allocation e. demand scheduling f. performance analysis and reporting g. shadow billing h. engine/generator efficiency studies Powermonitor Display Module The Powermonitor provides electrical monitoring and control functions in a wide variety of applications.
Chapter 1 Overview Communication Links Many forms of communication can be used to transfer power data on a local data bus to the computer running the Powermonitor Software. The local data buses presently used by the Catalog Number 1400–DCU communications card are either the electrical standards RS–232C or RS–485 and Allen–Bradley Remote I/O link for PLCR (programmable logic controllers) processors.
Chapter 1 Overview Data Acquisition Features A Powermonitor has on–board Snapshot logging capability which allows each device to store instantaneous measured values (ex. Volts, Amps, kW, kVAR, etc.) at user–defined intervals ranging from 1 second to 400 days. A computer running the Powermonitor Software can up load and display Snapshot Logs, and save an entire log to a disk file for analysis at a later date.
Chapter A–B 2 System Requirements Computer Requirements The Powermonitor Software software package is designed to run on a Personal Computer AT, 286, 386, or a true IBM compatible. The computer must have a minimum 256K of RAM, an 80 column monochrome or color monitor, and either a 5–1/4” (360KB or 1.2MB) or 3–1/2” (720KB or 1.44MB) floppy disk drive. A hard disk drive is optional. The computer must also have a communications interface capable of supporting the required number of sites.
Chapter 2 System Requirements RS–232C vs RS–485 Communications The Powermonitor Software can communicate to all Powermonitors in the system either via the RS–232C electrical standard or via the RS–485 standard. The type of communication hardware required at each site is dependant on which of these electrical standards is used by the Powermonitors located at that site.
Chapter A–B 3 Installation Chapter Objectives This chapter discusses the installation of the Powermonitor Software. The installation procedure is divided into two phases. The first phase covers installation of the hardware used to implement the Powermonitor Software communications system between the computer running the Powermonitor Software and the Powermonitors. The second phase covers installation of the Powermonitor Software software on the computer.
Chapter 3 Installation Connection To A Single Powermonitor Via RS–232C This section provides the information necessary to connect the computer to a single Powermonitor via an RS–232C communications link. To install an RS–232C communications link, both the computer running the Powermonitor Software and the Powermonitor must be configured for RS–232C communications.
Chapter 3 Installation Figure 3.1 Connection to a Single Powermonitor via RS–232C Bulletin 1400 Powermonitor Important: Note cable pin–out numbers RS–232C Port TXD 1 (Case Ground) 3 2 7 RXD SG SHIELD (2) (3) (5) 25 Pin (9 Pin) IBM PC (DTE) RS232C Cable NOTES: 1. RS–232C Cables: 25 pin DB25 or 9 pin DB9, plug (male) or socket (female) depending on mating connector at computer serial port, 50 feet maximum length. 2.
Chapter 3 Installation ! ! ATTENTION: Never connect an RS–232C equipped device to the DATA+ or DATA– lines of an RS–485 equipped communication system. Doing so will damage the RS–485 driver circuits of every device within the site. ATTENTION: Converters such as the Catalog Number 1400–CC converter must always be used between devices that use RS232C/RS–485 communications standards.
Chapter 3 Installation Connection To Single Powermonitor Sites Via The Telephone Network This section provides the information necessary to implement a telephone modem link between the computer and sites with only single remote Powermonitors. Important: The multi–device remote site configuration outlined on page 3–8 should be used if more than one Powermonitor is to be installed at the remote site in the future, or if a single device at a remote site is located more than 50 feet from the telephone modem.
Chapter 3 Installation ! ATTENTION: Before connecting any communications cables, confirm that the Powermonitor is configured for RS–232C communications and the computer port has been configured for RS–232C operation. Refer to Publication 1400–800, ‘‘Bulletin 1400 Powermonitor Installation and Operation Manual,” to determine correct configuration of the port. The remote site requires a RS–232C cable between the modem and the serial port of the Powermonitor.
Chapter 3 Installation Modem Configuration Information Modems used with computers running the Powermonitor Software must be fully Hayes compatible. If the modems are configured via their communications ports, the Powermonitor Software will configure them automatically using a set of default commands. These commands assume that a standard Hayes modem is being used. If you are using a modem which requires a unique command set to configure it, refer to Appendix B for instructions on creating a special MODEM.
Chapter 3 Installation Modem Configuration Information Continued You will need to check the modem’s user’s guide for the codes applicable to, and appropriate for your modem. Connection To Multiple Powermonitor Sites Via The Telephone Network Modem sites having more than one device are similar to sites with one device except that a Catalog Number 1400–CC RS–232C to RS–485 converter must be used and the Powermonitor communications card must be configured for RS–485 communications.
Chapter 3 Installation ! ATTENTION: Special high level isolation is required between units when the possibility of high ground potential differences exist. This may occur when separate grounds are used, or when communicating to a unit off of the power ground matt. Failure to do so can lead to personal injury or death, property damage, or economic loss. Important: For each site, total RS–485 cable length (Maximum 4,000–ft.
