5 / 6 page Protocol Specifications All BradCommunications™ Direct-Link™ networks interface cards for Profibus-DP support following protocols: DP-V0 Master/Scanner Class-1 & -2 and Slave modes simultaneously DP-V0 Slave passive mode only DP-V1 Master Class-1 & -2 (for PCU card) DP Master features DPV0 Master/Scanner Class-1 for optimized exchange of input/output data with the slaves (Data_Exchange). DP-V0 Master Class-2 for: Slave diagnostics Reading inputs/outputs of a slave Reading configuration data Changing the slave address. Access Modes DP-V1 Master Class-1 & -2: Read Data Block Class 1 Write Data Block Class 1 Read Data Block Class 2 Write Data Block Class 2 Abort Data Block Comm Class 2 Multi-master mode Yes (able to share the bus with other DP masters connected on the network) Watchdog control Yes, enables the master to switch into error if no data has been exchanged during this period (Bus Fault) Input/Output Data Memory of I/O data image: o PC/104: up to 2Kbytes o PCI-Universal: up to 8Kbytes o PCI Express: up to 8Kbytes o CompactPCI: up to 4Kbytes Manage up to 244 data bytes per slave Automatic organization of I/O data in the DPRAM memory Max. DP Slave Connect up to 126 slaves Data consistency Yes (i.e. user gets the data up to 122 bytes of a slave from one and the same DP cycle) Data format Direct access to variable types (bit, byte, word, double word) Local DP slave Run simultaneously with Master modes. Offers data exchange with another master on the network. The size of the input and output data is user-definable, and all exchange combinations are possible (from 0 to 244 bytes). The slave can ensure data consistency up to 122 bytes. (see DP-Slave features below for details). DP Slave passive features Access Mode DP-V0 Slave passive (no management of Profibus token) Input memory size Configurable from 0 to 244 bytes Output memory size Configurable from 0 to 244 bytes Slave address Configurable from 0 to 126 by software configuration GSD files Provided on the CD-Rom Data Format Configurable Intel or Motorola Address Assignment Master (Set_Slave_Address) Not supported Extended Diagnostic Not supported Direct-Link™ Profibus-DP |
