SUPERtrol II Flow Computer305.8 RS-232 Serial Port OperationThe RS-232 serial port can be used for programming (using the Setup Disk) or forcommunicating to printers and computers in the Operating Mode (Run Mode). Enhanceduses include remote metering by modem.5.8.1 PC Communications:The Setup Disk also allows the user to query the unit for operating status such as FlowRate, Flow Total, Temperature, Pressure, Alarm Setpoints, etc.In this mode of operation the RS232 port is assumed connected to acomputer. The SUPERtrol II will act as a slave and answer requests from the PC. Seethe Universal Protocol Users Manual for a complete listing of the commandsset supported. A DDE/OPC Server is also available for use in exchanginginformation with DDE Clients such as Spread Sheets, Database Programs, andHMI software.5.8.2 Operation of RS-232 Serial Port with Printers:Transaction PrintingFor transaction printing, the user defines the items to be included in the printed document(see section 6.13 COMMUNICATION, Print List). The transaction document can beinitiated by pressing the PRINT key.Data LoggingThe user can select when (time of day) or how often (print interval) the data log is to bemade (see section 6.13 COMMUNICATION, Print Initiate). Information will be stored tothe datalogger and optionally output to the RS-232 port.System Setup and Maintenance ReportThe system setup and maintenance report lists all of the instrument setup parameters andusage for the current instrument configuration. The audit trail information and a statusreport is also printed. This report is initiated in the Service and Analysis Group (seesection 6.15 SERVICE & ANALYSIS, Print System Setup).5.8.3 Operation of RS-232 Serial Port with ModemsIn this mode of operation the RS232 port is assumed to be connected to a MPP2400N orsimilar telephone modem. The SUPERtrol II is responsible for communicating to a remotecomputer through the modem to perform such actions as:Answer incoming calls, process requests for information or action items or data log contentsor change setup parameters, call out daily readings to designed phone number, call outto designated phone number in the case of a designated exception or malfunction in theunit, terminating telephone calls if a connection is lost.5.9 RS-485 Serial Port OperationThe RS-485 serial port is intended to permit operation of the flow computer in a RS-485network. Access is limited to reading process variables, totalizers, error logs and toexecuting action routines such as clearing totalizers, alarms, and changing setpoints.5.10 Pause Computations PromptThe user will be prompted with a "Pause Computations" message when making significantsetup changes to the instrument. Pausing computations is necessary to make anysignificant changes. With computations paused, all outputs assume a safe state equalto that of an unpowered unit. Computations resume when exiting the setup menu.RS-232 Serial PortOperationPC CommunicationsRS-232 Serial PortOperation of RS-232 SerialPort with PrintersOperation of RS-232 SerialPort with ModemsRS-485 Serial PortOperationPause ComputationsPrompt |
