Modes
PROFIBUS-DP master board manufactured by molex has two motion modes; Master mode and Slave mode. However, do not select the Slave mode.
Master mode
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.
