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)
(Set_Slave_Address)
DPV0 Master/Scanner Class-1 for optimized exchange of input/output data with the slaves
(Data_Exchange).
DP-V0 Master Class-2 for:
DP-V1 Master Class-1 & -2:
Yes (able to share the bus with other DP masters connected on the network)
Yes, enables the master to switch into error if no data has been exchanged during this period
(Bus Fault)
Connect up to 126 slaves
Yes (i.e. user gets the data up to 122 bytes of a slave from one and the same DP cycle)
Direct access to variable types (bit, byte, word, double word)
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-V0 Slave passive (no management of Profibus token)
Configurable from 0 to 244 bytes
Configurable from 0 to 244 bytes
Configurable from 0 to 126 by software configuration
Provided on the CD-Rom
