8507-BI-DP  PROFIBUS DP Bus Interface Module and Carrier

The 8507-BI-DP Bus Interface Module (BIM) provides the communications link between the PAC8000
series I/O modules and a PROFIBUS-DP host. High-speed acquisition of data from the modules and LAN
operation speeds of up to 12 Mbaud allow the host to respond rapidly to changes in process conditions.
The BIM gathers data from the I/O modules and makes it available to the host upon request. It is a slave to
the PROFIBUS master. As well as cyclic data exchange, which is required for reading input and writing
output data, the BIM supports PROFIBUS Extended Diagnostics for status information.
The BIM(s) must be used with an 8701-CA-BI Redundant BIM Carrier, described on page 4.
Redundant BIMs can be used for critical applications. Each BIM in the redundant pair operates in parallel,
continually checking status to enable the backup BIM to monitor the health of the primary BIM.
