8521-HC-MT hybrid controller MTL

8521-HC-MT hybrid controller MTL

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.

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.

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.
