About this Guide This guide describes how to configure the Serial Status (Serial Status Protocol) Data Collection Application (DCA). Purpose of this Guide This document describes the purpose and use of each of the configuration parameters of the Serial Status DCA. This document makes no attempt to explain how the configuration process operates, it is limited to describing the format and content of the DCA configuration only.
Serial Status DCA Configuration Guide GE Energy Services A166-0CG-1.
Overview The Serial Status DCA software is installed in GE Energy Services WESDAC equipment to provide an interface to Sub-Remote Units (SRUs) using the Serial Status communication protocol. Product Perspective The Serial Status DCA software is custom software installed in the GE Energy Services Remote Terminal Unit (RTU) to act as a data concentrator for one or more SRUs using the Serial Status communication protocol.

Chapter 1: Configuring Tables The Serial Status DCA configuration contains all of the data structures necessary to configure a RTU to poll devices using the Serial Status protocol. 1.1 Serial Status DCA Configuration Tables The purpose of each configuration table is described below. TABLE NAME DESCRIPTION A166APPL The Main Application configuration table is used to define global settings for the entire Serial Status application.
Serial Status DCA Configuration Guide GE Energy Services error, terminate or continue with its run-time function. 5. Check for error messages. Log into the WESMAINT maintenance interface, select the System Functions item from the Main Menu, and then select the Error Log item from the System Functions Menu. If any error messages are displayed, correct the problem as described in Appendix A:, and repeat steps 3 through 5.
Chapter 2: Configuring the Main Application Table (A166APPL) The Main Application configuration table is used to define global settings for the entire Serial Status DCA. These parameters pertain to all channels and SRUs connected within the system. The Main Application configuration must contain a single record. Name DCA Index Range Description Index into the System The indexed System Point Database table record must contain the Point Database WESDAC database point counts for this application.

Chapter 3: Configuring the Port Table (A166PORT): The Port table contains the relevant configuration information for communication port setup. Each record in the Port table defines the communication parameters for a single communication port. Name Range Description Communication Port Any valid communication port (hardware dependent) This parameter contains the ASCII descriptor for the communication port to use. For example, for the D20 valid communication ports are “COM1" through “COM7".
Serial Status DCA Configuration Guide GE Energy Services The following port parameters are fixed and can not be changed by user. • Baud rate is set at 9600 baud • All modem control signals are disabled. A166-0CG-1.
Chapter 4: Configuring Win for the Serial Status DCA This chapter describes how to configure the WIN application to work with the Serial Status DCA. The WIN application allocates the WESDAC data points for all applications. In order to work properly the Serial Status DCA must have its own record within the WIN application's System Point Database. This record is referenced by the DCA Offset specified in the Main Application configuration table.

Appendix A:Messages Logged by the Serial Status DCA This appendix contains a description of all error messages posted to the WESMAINT Error Log by the Serial Status DCA. This appendix also provides an explanation of all output return codes returned by the Serial Status DCA. During startup, the Serial Status DCA checks its configuration tables for invalid entries. If no configuration errors are encountered the DCA attempts to spawn a number of processes during start-up.
Serial Status DCA Configuration Guide GE Energy Services F002: Unable to locate WESDAC_ table Cause • The DCA was unable to locate one of the required WESDAC data base tables. Remedy: • Ensure the WESDAC_ table exists in the WIN application and is comprised of at least one record. Refer to the chapter on configuring WIN for more information on configuring WESDAC points. F003: Insufficient WESDAC_ points, req’d Cause • There are not enough WESDAC data points allocated to the Serial Status DCA.
Serial Status DCA Configuration Guide GE Energy Services F006: Error creating event exchange, status= Cause • The system was unable to create a message exchange for the event process. This message exchange is vital to the operation of the entire application. Remedy: • Contact the Customer Service Department and report this error. F007: Unable to spawn event process Cause • The system was unable to start the event process. The event process is vital to the operation of the entire application.
Serial Status DCA Configuration Guide GE Energy Services Remedy: • Ensure the CFG_DCA table in the WIN application is configured with a record containing the WESDAC points to be allocated for the Serial Status DCA. • A.2 Ensure the DCA Index configured in A166APPL points to the correct record in the WIN CFG_DCA table. Non-Fatal Error Messages These messages indicate the application has encountered a non-fatal configuration error or a nonfatal stage of process initialization failed.
Serial Status DCA Configuration Guide GE Energy Services E004: Unable to spawn scan process, rec Cause • The system encountered an error while trying to spawn one of the scan processes. Effect: • One of the scan processes will not be started. As a result, the Serial Status DCA will be unable to communicate over the communication port configured in record of A166PORT. Remedy: • Contact the Customer Service Department and report this error.
Serial Status DCA Configuration Guide GE Energy Services E012: unable to set timers, status = Cause • The system was unable to set the communication timers for the specified communication port. Effect: • The Serial Status DCA will be unable to communicate over the port, . Remedy: • Note the return status, , and contact the Customer Service Department to report this error.
Serial Status DCA Configuration Guide A.3 GE Energy Services Warning Messages Warning messages indicate recoverable run-time errors, either within the application or through one of the software interfaces. The application will attempt to handle these errors without suspending or jeopardizing the integrity of the system. If a warning message occurs repeatedly, contact the Customer Service Department to report the error.
Serial Status DCA Configuration Guide GE Energy Services I101:A166PORT rec , Resp Timeout < , defaulting Cause • The Response Timeout configured in one of the port records is too small Effect: • The Response Timeout in record of A166PORT will default to a typical value (1000 character times). Remedy: • ·Refer to the chapter entitled Configuring the Port Table and ensure a valid Response Timeout is configured in record of A166PORT.
