4. ax of declaration of transmission channel working according to the DataPAF protocol is given below logical name DataPAF COMn where COMn number of the serial port to which the DataPAF energy counter is connected Each defined channel may have its own section the name of which is a logical name of the channel It contains parameters for the given channel Some channels may have a common serial port Also the given port COMn may have its own section named DataPAF n It defines parameters of the serial port 1 3 Driver Configuration The default values of serial interfaces are retrieved from the section DataPAF if section exists This section 15 used to configure all the channels for the DataPAF protocol which are declared in this system NUMBER number serial Number number Meaning determines an identification number of the DataPAF counter Input of incorrect number makes the communication impossible Default value 1234 Parameter number counter number baud number bps number Meaning determines transmission speed Default value 4800 Parameter number transmission speed in Bd ASKOM Gliwice August 2005 3 DataPAF Driver of DataPAF Energy Counter Protocol 51 4 diagnostics number Meaning declaring this position with value 14 will cause outputting the diagnostic information connected with time synchronization to the log file Default value 0 Parameter numbe
5. k alarm Code number Meaning Default value the parameter determines the number of an alarm generated by the driver in case of loss and re establishing of connection with the station The value of 1 default causes that alarms are not generated In a situation of a connection loss a number specifying the cause of connection loss is transferred together with the alarm code 0 complete lack of any answer from the station timeout 2 line errors frame parity overrun errors 3 checksum errors 4 other errors This number determines the end status of the last attempt of connection establishing lack v energy error number Meaning Default value determines situations when the status of the XEN variable value assumes an error value and it is the sum of the following values 1 error when a short decay of voltage 2 error when a long decay of voltage 4 error when a pause in input line of the impulse counter 0 August 2005 ASKOM Gliwice asix4 4 DataPAF Driver of DataPAF Energy Counter Protocol mult number Meaning defines a value of all input multipliers Input multipliers are used for calculating the energy on the basis of the impulse number If this parameter is given then the driver will not read values of multipliers from the energy counter If beside the parameter mult parameters determining values of multipliers for individual channe
6. ls multn are also used then the parameter mult must be placed before all parameters multn Default value lack Parameter number the multiplier 15 a floating point number number Meaning defines an input multiplier value for a channel with the number n 1 31 Input multipliers are used for calculating the energy on the basis of the impulse number If this parameter is given then the driver will not read values of multipliers from the energy counter If the parameter mult is also given then it must be placed before all parameters multn Default value lack Parameter number the multiplier is a floating point number EXAMPLE datapaf definition of multiplier for all channels mult 2 7 definition of multiplier for channel 6 mult6 3 3 1 4 Driver Parameterization Examples EXAMPLE ASMEN KOMIN 2 DataPAF 2 DataPAF 2 baud 19200 Numer 4800 In the above example the station named KOMIN 2 connected to the port COM2 is defined The transmission speed of 19200 bps will be used ASKOM Gliwice August 2005 7 DataPAF Driver of DataPAF Energy Counter Protocol 51 4 In case of time synchronization of asix station with the time of a chosen counter definition of this time should be placed in the ini section for the given counter For this purpose the parameter system sync to which the value of allowed difference of times in seconds is assigned EXAMPLE
7. r 14 v parity parity parameter Meaning determines parity Default value N Parameter parity parameter allowed value n no parity bit o odd parity check e even parity check m mark 5 Space v stop bits number Meaning determines a number of stop bits Default value 1 Parameter number allowed values are 1 and 2 word number word length number Meaning determines word length Default value 8 Parameter number allowed values are from the range of 5 to 8 tine out number timeout number Meaning waiting time for the DataPAF answer Default value 1000 Parameter number in miliseconds v repetitions number Meaning number of repetitions of communication operations ended with an error Default value 3 4 August 2005 Gliwice asix4 DataPAF Driver of DataPAF Energy Counter Protocol Parameter number number of repetitions v max Time Difference number Meaning determines the maximal difference between the asix system time and the DataPAF counter time after which warnings will be generated in Control Panel The station time can be read with an interval defined by the parameter time Check Default value 60 Parameter number number in seconds time Check number Meaning interval with which the current time of the counter 15 read Default value 180 Parameter number number in seconds v system sync numbe
8. r Meaning maximal difference between the asix system time and the DataPAF counter time after which a system time synchronization with the counter time will occur If the parameter value is 0 then the system time 15 not synchronized with the counter time Default value 0 Parameter number number in seconds v period Check number Meaning interval with which the change of current calculation period of the counter is checked Default value 180 Parameter number number in seconds max history number Meaning determines a time period from the current moment backwards for which historical data saved in station memory will be read Default value 35 Parameter number number in days Gliwice August 2005 5 DataPAF Driver of DataPAF Energy Counter Protocol v history Buffer Removal number Meaning Default value Parameter number the parameter determines a time period after which buffers containing historical data read for needs of an archiving module are removed 120 the time is given in minutes v CRC1I6 YES NO Meaning Default value determines if the CRC16 validity check has to be used in the communication with the counter If NO is given then the sum of sequent bytes will be calculated YES v log file name Meaning Default value the parameter determines the name of file to which additional diagnostic information will be written lac
