Wiring of the PROFIBUS DP Network

This chapter describes how to connect the LTMR controller to an RS 485 PROFIBUS DP network with a SUB-D 9 or an open-style connector.

WARNING
LOSS OF CONTROL The designer of any control scheme must consider the potential failure modes of control paths and, for critical functions, provide a means to achieve an acceptable state during and after a path interruption. Separate or redundant control paths must be provided for critical control functions. System control paths may include communication links. Consideration must be given to the implications of anticipated transmission delays or interruptions of the link. Observe all accident prevention regulations and local safety guidelines.* Each implementation of an LTMR controller must be individually and thoroughly tested for proper operation before being placed into service. Failure to follow these instructions can result in death, serious injury, or equipment damage.
