The specifications of the PROFIBUS-DP Master function differ depending on the CNC model and the series of CONTROL SOFTWARE.
In PROFIBUS-DP communication, two types of nodes are involved: a master station (also referred to as a DP-Master) and a slave station (also referred to as a DP-Slave). DI/DO data is exchanged between a DP-Master and DP-Slave according to a data exchange request from the DP-Master. The DP-Master function is referred to as the PROFIBUS-DP Master (class1) function (simply referred to as the master function). The DP-Slave function is referred to as the PROFIBUS-DP Slave function (simply referred to as the slave function).
Two classes of DP-Masters are used in PROFIBUS-DP communication: class1 and class2. A DP-Master (class1) is a DP-Master that communicates with DP-Slaves. A DP-Master (class2) is a DP-Master that serves as the management station within a PROFIBUS-DP system and communicates with the DP-Master (class1).
The master function of FANUC CNCs supports only the DP-Master (class1) function, so that the FANUC DP-Master cannot be used as a DP-Master (class2).
To use the master function, bus parameters and slave parameters must be set, and addresses must be assigned. The bus parameters are referenced by the network, and the slave parameters are set for each slave. In address assignment, PMC addresses used by the DP-Master to transfer DI/DO signals to and from each DP-Slave are set.
NOTE: PROFIBUS-DP cannot be used with DeviceNet.
