8507-BI-DP BIM and 8701-CA-BI Carrier

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 tothe 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.
