FUNCTIONAL DESCRIPTION:

IC693PBM200 is a Profibus DP Master Module manufactured and designed by GE Mark II Series as part of the GE Speedtronic Gas Turbine Control Systems. The Master module enables an IC693 PLC to communicate I/O data over a PROFIBUS DP network. Key features include support for Sync and Freeze modes, along with LED indicators for PROFIBUS-compliant COM and SYS functions. Firmware updates can be performed via the service port. The module accommodates all standard data rates and manages up to 125 DP slaves, supporting 244 bytes of input and output per slave. Configuration requires ME Logic Developer PLC programming software, version 3.0 or later. When transitioning from the HE693PBM101 PROFIBUS Master Module, users should note certain considerations. It has a default slave status area of 128 points—double the 64-point allocation of the HE693PBM101. Adjustments may be necessary to align the slave status area size with the previous module's configuration. This module allows an IC693 PLC to send and receive I/O data from a PROFIBUS DP network. The feature set includes:

• Support for all standard data rates (9600 – 12M)
• Support for up to 125 DP slaves
• Support for 244 bytes of input and 244 bytes of output for each slave
• Support for Sync and Freeze modes
• PROFIBUS-compliant COM and SYS LED indicators
• Firmware update via service port on module

OPERATIONS:

• The default slave status area for the Module is 128 points, whereas the HE693PBM101 uses 64 points. Users may need to adjust the slave status area size to align with the previous module’s configuration.

• The IC693PBM200 enters Clear Mode when the PLC is not scanning its I/O, a behavior not present in the HE693PBM101.

• In the HE693PBM101, slave status bits are arranged based on their configuration order, while in the Module, they are organized by bus address.

• For diagnostic data handling, the HE693PBM101 uses separate bits and data areas for each slave. In contrast, the Module uses a word of optional input data to notify the application program of diagnostic data availability. This data is retrieved via a COMM_REQ function block, eliminating the need for the Diagnostic Flag area, Diag_Data Slave Addr area, and Diag Data area used in the HE693PBM101.

• The HE693PBM101 includes a single Module Revision input word, whereas the IC693PBM200 combines this with a new Slave Diag ID input word into an optional 2-word input area. To mimic the behavior of the HE693PBM101, users may choose to disable fault reporting in the Module.

FREQUENTLY ASKED QUESTIONS:

What is the PROFIBUS DP Master Module used for?

The PROFIBUS DP Master Module is designed to facilitate communication between an IC693 PLC and a PROFIBUS DP network. It enables the PLC to exchange I/O data with up to 125 DP slaves, supporting standard data rates. It operates in Sync and Freeze modes and includes LED indicators for monitoring the COM and SYS signals. The module allows users to update firmware via a service port and can handle 244 bytes of input and output per slave.

What software is required to configure the PROFIBUS DP Master Module?

To configure the PROFIBUS DP Master Module, users need to utilize the ME Logic Developer PLC programming software, version 3.0 or later. This software is essential for setting up the module, managing its configurations, and ensuring that the PLC communicates properly with the PROFIBUS DP network.

How does diagnostic data retrieval differ between the Master Module and the HE693PBM101?

The diagnostic data retrieval process is different between the two modules. The HE693PBM101 uses separate bits and data areas for each slave to detect and retrieve diagnostic data. In the IC693PBM200, a word of optional input data informs the application program of diagnostic data availability from a slave. The actual data is then retrieved using a COMM_REQ function block, eliminating the need for the Diagnostic Flag area, Diag_Data Slave Addr area, and Diag Data area that was used by the HE693PBM101.
