Appendix A. CRBasic Programming Instructions The Timeout argument is entered in units of hundredths (0.01) of seconds. If 0 is used, then the default timeout, defined by the time of the best route, is used. Use PakBusGraph Hop Metrics to calculate this time (see datalogger support software (p. 89) ). Because these communication instructions wait for a response or timeout before the program moves on to the next instruction, they can be used in a SlowSequence scan. A slow sequence will not interfere with the execution of other program code. Optionally, the ComPort parameter can be entered preceded by a dash, such as -ComME, which will cause the instruction not to wait for a response or timeout. This will make the instruction execute faster; however, any data that it retrieves, and the result code, will be posted only after the communication is complete. AcceptDataRecords Sets up a CR6 to accept and store records from a remote PakBus datalogger. Syntax AcceptDataRecords(PakBusAddr, TableNo, DestTableName) Broadcast Sends a broadcast message to a PakBus network. Syntax Broadcast(ComPort, Message) ClockReport Sends the datalogger clock value to a remote datalogger in the PakBus network. Syntax ClockReport(ComPort, RouterAddr, PakBusAddr) DataGram Initializes a SerialServer / DataGram / PakBus application in the datalogger when a program is compiled. Syntax DataGram(ComPort, BaudRate, PakBusAddr, DestAppID, SrcAppID) DialSequence / EndDialSequence Defines the code necessary to route packets to a PakBus device. Syntax DialSequence(PakBusAddr) DialSuccess = DialModem(ComPort, DialString, ResponseString) EndDialSequence(DialSuccess) EncryptExempt Defines one or more PakBus addresses to which the datalogger will not send encrypted PakBus messages, even though PakBus encryption is enabled. 562
