Add a Profibus DP Slave PCI Expansion Module
With the Profibus protocol the data is exchanged according to the master-slave principle. Only the master can initialize communication. The slaves respond to requests from masters. Several masters can coexist on the same bus. In this case, the slave I/O can be read by all the masters. However, a single master has write access to the outputs. The number of data items exchanged is defined during the configuration.
For the Profibus Master, the GSD file of the TM5 Profibus DP PCI module is available on www.schneider-electric.com.
There are 2 types of exchange services supported by this module:
oacyclic data exchanges with Profibus DPV1 function
Add a Profibus DP Slave PCI Expansion Module
Add a Profibus DP slave PCI expansion module to your project, as described in the Add a PCI Expansion Module chapter, by selecting the TM5PCDPS module.
NOTE: Adding Profibus increases the associated task cycle time by several milliseconds and the starting time by several seconds.
