Moiton Mode
PROFIBUS-DP master board has two motion modes; Master mode and Slave mode.
However, do not select the Slave mode.
Master Mode
There are two types of PROFIBUS DP master: DPM1 and DPM2. DPM1 (DP Master
Class 1) gathers and controls all stations in one PROFIBUS DP network. DPM2 (DP
master Class 2) operates network configurations, network maintenance, and diagnosis.
PROFIBUS DP master can control up to 126 stations (max. 128 bytes) in one network.
PLC is typically configured as a master and controls all devices in factory automation
system, but EPSON RC+ is also capable of being a master.
PROFIBUS DP network configuration is specified by the configuration management
software. This software is normally provided by a master device manufacturer. The
configuration management software determines parameters for each slave device via an
Electronic Data Sheet (GSD).
The connection type is token passing procedure and master-slave communication. The
token passing procedure is applied to the PROFIBUS DP network with more than two
master devices to transfer network control between masters. The master-slave
communication is applied to the communication between the master device with network
control and its slave devices.
Available baud rates are 9.6 kbps, 19.2 kbps, 93.75 kbps, 187.5 kbps, 500 kbps, 1500 kbps,
3 Mbps, 6 Mbps, and 12 Mbps.
For the instruction of configuration, refer to the section Master Mode.
