PROFIBUS / PROFIsafe - Commissioning 6.7.2 iParameters (F_iPar) Application-dependent device characteristics are defined with the iParameters. A CRC calculation is necessary for safe transmission of the iParameters, see chapter "iParameters" on page 159. The iParameters supported by the measuring system are listed below. Byte order = Big Endian Byte Parameter Type Description Page X+0 X+2 X+4 X+6 Integration time Safe Integration time Unsafe Window increments Idleness tolerance Preset X+7 Direction Bit 6.7.2.1 Integration time Safe Unsigned16 Unsigned16 Unsigned16 Unsigned8 Default = 2 Range: 1-10 Default = 20 Range: 1-100 Default = 1000 Range: 50-4000 Default = 1 Range: 1-5 0: Decreasing counting direction 1: Increasing counting direction [default] This parameter is used to calculate the safe speed, which is output via the cyclical data of the PROFIsafe module. High integration times enable high-resolution measurements at low speeds. Low integration times show speed changes more quickly and are suitable for high speeds and high dynamics. The time basis is predefined to 50 ms. 50…500 ms can thus be set using the value range of 1…10. Standard value = 100 ms. 6.7.2.2 Integration time Unsafe This parameter is used to calculate the unsafe speed, which is output via the process data of the PROFIBUS module. High integration times enable high-resolution measurements at low speeds. Low integration times show speed changes more quickly and are suitable for high speeds and high dynamics. The time basis is predefined to 5 ms. 5…500 ms can thus be set using the value range of 1…100. Standard value = 100 ms. 6.7.2.3 Window increments This parameter defines the maximum permissible position deviation in increments of the master / slave scanning units integrated into the measuring system. The permissible tolerance window is basically dependent on the maximum speed occurring in the system and must first be determined by the system operator. Higher speeds require a larger tolerance window. The value range extends from 50…4000 increments. Standard value = 1000 increments. 6.7.2.4 Idleness tolerance Preset This parameter defines the maximum permissible speed in increments per Integration time Safe for performance of the preset function. The permissible speed is dependent on the bus behavior and the system speed, and must be determined by the system operator first. The value range extends from 1 increment per Integration time Safe to 5 increments per Integration time Safe. Standard value = 1 increment per standard value Integration time Safe. 157 157 157 157 158 Printed in the Federal Republic of Germany © TR-Electronic GmbH 2010, All Rights Reserved 05/25/2011 TR - ECE - BA - DGB - 0079 - 03 Page 157 of 207
PROFIBUS / PROFIsafe - Commissioning 6.7.2.5 Direction This parameter defines the current counting direction of the position value looking at the flange connection, turning the shaft clockwise. Forward = Counting direction increasing Backward = Counting direction decreasing Standard value = Forward. © TR-Electronic GmbH 2010, All Rights Reserved Printed in the Federal Republic of Germany Page 158 of 207 TR - ECE - BA - DGB - 0079 - 03 05/25/2011
