Eaton MTL PAC8000 8507-BI-DP BIM and 8701-CA-BI Carrier PROFIBUS DP Bus Interface Module and Carrier

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.

8507-BI-DP Bus Interface Module

For details on the installation and operation of the BIM, refer to the PAC8000 I/O

- PROFIBUS DP BIM Instruction Manual, INM8507.

Features

 support for up to 24 I/O modules

 redundant operation

 extended diagnostics for module and channel status

 PROFIBUS network speeds of up to 12 Mbaud

 non-volatile memory for configuration

 configurable via PROFIBUS host

 HART Pass-through support to monitor/configure HART devices

 Configuration/Reset of IP address

Parameterization

The 8507-BI-DP supports parameterization from the PROFIBUS master.

The configuration is created in a PROFIBUS configurator using details provided in

a GSD file. This method is fast and enables a configuration to be built based upon

“logical” modules which represent the physical modules. Modules are added one

at a time to the configuration.

The configuration is passed from the PROFIBUS master to the BIM at the start of

communication. If the system is stopped and re-started, or if the node goes through

a cold start cycle, the configuration file is retransmitted to the BIM.

Standard and Extended Diagnostics

The PROFIBUS BIM supports Standard and Extended Diagnostics. While the Standard

Diagnostics provide standard PROFIBUS status information, the Extended Diagnostics

provide detailed information relating to the status of the BIM, the health of the modules

and the status of I/O channels. Depending on the I/O module type, events such as high

and low alarm, open circuit and line fault are detected.

Extended Diagnostic messages are generated on detection of any anomalies in I/O

modules. Use of the diagnostic capability requires suitable support in the host application.

For hosts unable to use diagnostic data in the control algorithm, it is possible to map the

diagnostic data into the input dataframe.
