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

Date: Dec 24, 2024Views:

　　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.

　　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.

　　Important Product Information for this Release

　　This release resolves the incompatibility between the 8507-BI-DP bus interface module and the 8123-PI-QU/8223-PI-IS pulse input modules. The 8507-BI-DP module’s firmware is updated to support these two modules; there is no change in hardware.

　　Functional Compatibility

　　Unsupported Modules

　　The 8507 PROFIBUS DP BIM does not support the 8129-IO-DC, 8132-AI-UN, 8133-HI-TX, 8140-DI-AC and 8142-DO-DC modules.

　　8127-DI-SE sequence of events functionality not supported

　　The 8127-DI-SE module can be used with the 8507 PROFIBUS DP BIM. However the BIM does not support the Sequence Of Events functionality.

　　64-slot address bus module carriers are not supported

　　The 8507 PROFIBUS DP BIM only supports 32-slot address bus module carriers. The 8709-CA-08 and 8729-CA-08 module carriers are not supported.

　　Module diagnostics do not work with Delta V

　　Delta V PROFIBUS masters do not report a module removal fault when a module is removed from the 8507-BI-DP’s backplane. In this situation, all of the module’s channel diagnostics report a bad channel status, which is the only indication provided that the module is not present.

　　The standalone I/O Configuration software does not support 8507-BI-DP for IO module configuration

　　The standalone I/O Configuration software does not support the 8507- BI-DP. The 8507-BI-DP can be configured only through the GSD file using a PROFIBUS master. The 8507-BI-DP cannot be configured on a per-channel basis.

　　Compatibility with GEF01 Rev. C and earlier

　　When using module GE02 Rev. B with earlier versions of modules in redundant configuration, earlier version modules start-up faster compared to GE02 Rev. B version. As a result, earlier version modules will always be master after start-up.

　　It is recommended that both BIMs in a redundant configuration have revision GE02 Rev. B or higher firmware.

　　Support of HART Pass-through over Ethernet

　　The support for HART Pass-through over Ethernet is implemented as part of this release.

　　The new firmware version 1.23 corrects this issue.

　　The GSD file offers incorrect configuration options for Analog Input modules

　　The 8507-BI-DP GSD file incorrectly provides the options of open circuit and short circuit detection for analog input modules 8101, 8103, 8119 and 8201.

　　The default configuration setting (“off”) for “O/C detection” and “S/C detection” parameters should not be changed when configuring these modules with the GSD file.

　　For 8123/8223 PI module, some of the configuration options given in 8507-BIDP GSD file are not applicable.

　　For the Digital Output parameter of 8123/8223 PI module, only the options Not Used and Counter Preset Reached are applicable. Other configuration options should not be used while configuring the Digital Output parameter from the GSD file.

　　8507 PROFIBUS DP BIM configuration

　　Configuration of the PROFIBUS network address is done via rotary switches on the carrier. Configuration is delivered to the PROFIBUS DP BIM over the PROFIBUS network from a PROFIBUS master (parameterization). A GSD file for the PROFIBUS BIM and supported modules is available for creating a configuration in a PROFIBUS configuration package. The GSD file can be downloaded from the support website. The PROFIBUS DP BIM cannot be configured using the standalone Workbench IO Configuration software.

　　PROFIBUS network speeds

　　The 8507 PROFIBUS DP BIM supports all speeds up to 12MBps

　　Replacing an 8502 PROFIBUS DP BIM with an 8507 PROFIBUS DP BIM

　　The following differences should be considered when replacing an 8502 PROFIBUS BIM with an 8507 PROFIBUS BIM.

　　The 8701-CA-BI carrier must be used with the 8507 PROFIBUS BIM. The carriers for the 8502 PROFIBUS BIM are not compatible with the 8507 PROFIBUS BIM.

　　The parameterization data has changed slightly for the 8507 PROFIBUS BIM. A new GSD file is required to be used with PROFIBUS configuration software.

　　The LEDs on the face of the 8507 PROFIBUS BIM have changed. See INM8507 for a description of the LEDs on the 8507 PROFIBUS BIM

　　The bits in the status word are significantly different between the 8502 and 8507 PROFIBUS BIMs. See INM8507 for a description of the status word on the 8507 PROFIBUS BIM.

　　Bit 0 in the control word “Scan BIM” is not required to be sent to the 8507 PROFIBUS BIM. This bit is unused in the 8507.

　　Bit 5 in the control word “15 bit analog data format” is not supported in the 8507 PROFIBUS BIM.

　　Scaling of Temperature Input Data (including mV & ohms) is different in the 8507 PROFIBUS DP BIM. See INM8507 for a description of the operation.

　　Parameterization over a PROFIBUS network does not allow independent channel configuration. All channels must be configured the same. An 8502 PROFIBUS DP BIM could be configured using the IO Configurator software. The IO Configurator software cannot be used with the 8507 PROFIBUS DP BIM.

　　Up to 24 modules supported

　　The 8507 PROFIBUS DP BIM supports a maximum of 24 modules.

　　PROFIBUS DPV1 not supported

　　The 8507 PROFIBUS DP BIM does not support PROFIBUS DPV1.

　　HART data acquisition is not supported

　　The 8507 PROFIBUS DP BIM does not support HART data acquisition. HART data acquisition should not be used when configuring HART modules with the GSD file.

　　Latching on Digital Input module does not clear

　　The 8507 PROFIBUS DP BIM does not support latching for Digital Input modules. This functionality should not be enabled when configuring a Digital Input module with the GSD file.

　　8507 PROFIBUS BIM and IO Module power-on states

　　When the BIM powers-on, the IO modules respond to IO data received over PROFIBUS, if the PROFIBUS network is in “Operate” mode and the master is actively sending IO data to the BIM when it powers-on. If the PROFIBUS network is disconnected or in “Clear” mode when the BIM powers-on, the BIM enters failsafe mode. The BIM remains in Failsafe mode until the “Exit Failsafe Mode” control bit (Control Word Bit 15) changes state from a zero to a one. Subsequently, the IO modules respond to any IO data received over PROFIBUS.

　　8507-BI-DP transmits status word in bigendian format and reads control word in big-endian format.

　　The 8507 transmits the most significant byte of the status word first and the least significant byte last. While reading the control word, the 8507 treats the first byte of the control word as the most significant byte. The second byte is the least significant byte.

　　In the 8101 analog input module, fail state settings are ignored for deactivated channels.

　　The 8507-BI-DP ignores the configured “Failstate” setting in the GSD file for channels that are configured as inactive. All inactive channels are forced to “hold last state”.

　　Digital input data format for eight-input Digital modules

　　When an eight-input Digital module is configured for counter operation, PROFIBUS presents the digital inputs as word data. The most significant byte contains the states of inputs 1–8 and the least significant byte contains all 0s

　　This behavior applies to the following modules:

　　8109-DI-DC

　　8110-DI-DC

　　8111-DI-AC

　　8112-DI-AC

　　8113-DI-AC

　　8114-DI-AC

　　8220-DI-IS(8-input configuration)

　　ncrease in start-up time after power cycle and firmware update

　　The start-up time of 8507 Profibus BIM is approximately 15 seconds for firmware versions 1.23 (boot code 2.00) and higher.

　　Invalid firmware update When invalid firmware is downloaded, the module’s fault LED will

　　When invalid firmware is downloaded, the module’s fault LED will blink for a period of 60 seconds. After the timeout of 60 seconds the module is reset and remains in firmware upgrade mode.

　　To recover the module, download a valid firmware version.
