GE HE693PBS106 Communication interface module

The Profibus Slave User Manual describes the operation, configuration, and physical characteristics of the PROFIBUS Slave device. The Horner Electric HE693PBS106 provides the GE Fanuc PLC with a flexible communications interface to PROFIBUS networks for Decentralized Peripherals (DP). The HE693PBS106 operates as PROFIBUS DP modules only. They do not support the other types of Profibus (FMS, PA). The PROFIBUS utilizes a Master-Slave type of communication with the HE693PBS106 functioning as the slave device. Decentralized Peripherals (The Slave) include but are not limited to: input/output devices, drives, valves, and measuring transmitters. DP’s are mainly used to connect programmable controllers to the above devices via a high speed serial link. Baud rates of up to 12 MBd can be obtained through PROFIBUS. Up to 32 devices (masters or slaves) can be connected in one segment without using repeaters, or up to 64 devices can be connected using repeaters. Master devices are used to determine the data communication on the bus. One master can service several slaves. Several Masters can participate on the bus simultaneously, but a slave can only receive outputs from one master. The slave devices are peripheral devices that include input/output devices, valves, and drives. Slaves do not have bus access rights and can only acknowledge received messages or send messages to the master when requested to do so. Any master can read data from the Slaves. All connected Slaves have the same priority.
