FUNCTIONAL DESCRIPTION OF IS220PPRFH1A Rev D:

The IS220PPRFH1A Rev D is a PROFIBUS Master Gateway (PPRF) I/O Module designed and manufactured by General Electric for the Distributed Mark VIe turbine control systems. The PROFIBUS Master Gateway (PPRF) pack is a PROFIBUS DPV0, Class 1 master that maps I/O from PROFIBUS slave devices to Mark* VIe controllers on the I/O Ethernet. The module contains a processor board common to all Mark VIe distributed I/O modules and an acquisition carrier board fitted with a COM-C PROFIBUS communication module supplied by Hilscher GmbH. The COM-C module provides a PROFIBUS RS-485 interface through a DE-9 D-sub receptacle connector. It serves as a PROFIBUS DP master supporting transmission rates from 9.6 KBaud to 12 MBaud and up to 125 slaves with 244 bytes of inputs and outputs per slave. The PPRF supports the following redundancy options:

• Single I/O pack with single I/O Ethernet connection (no redundancy)
• Single I/O pack with dual I/O Ethernet connections
• Hot-backup I/O pack with dual I/O Ethernet connections

The dual I/O Ethernet connection configuration is common to other IO packs. However, in the hot-backup, two PPRFs are employed, one operating as the active PROFIBUS master communicating with slave devices, and the other operating in a passive, stand-by mode, ready to become the active master in the event of an active master failure.

COMPATIBILITY:

The PROFIBUS Master Gateway Terminal board (SPIDG1A) is used to mount the PPRF and to supply an electronic ID. Its only connection is the interface to the PPRF itself, as the PROFIBUS connection is made to the DE-9 D-sub receptacle connector exposed on the side of the PPRF. Visual diagnostics are provided through indicator LEDs on the PPRF. An infrared port provides local diagnostic serial communication.

INSTALLATION:

• Directly plug the PPRF into the terminal board connector. For hot-backup configurations, repeat steps 1 and 2 with a second SPID and PPRF.
• Mechanically secure the packs using the threaded inserts adjacent to the Ethernet ports. The inserts connect to a mounting bracket specific to the terminal board type. The bracket should be adjusted so there is no right-angle force applied to the DC-37 pin connector between the pack and the terminal board. This adjustment is required once during the life of the product.
• Plug in one or two Ethernet cables depending on the system configuration. The pack operates over either port. If dual connections are used, standard practice is to hook ENET1 to the network associated with the R controller; however, the PPRF is not sensitive to Ethernet connections and will negotiate proper operation over either port.
• Connect and secure the PROFIBUS cable into the DE-9 D-sub receptacle connector. As per PROFIBUS requirements, the PROFIBUS must be terminated on either end.
• Apply power to the connector on the side of the pack. It is not necessary to insert the connector with power removed from the cable. The PPRF has inherent soft- start capability that controls current inrush on power application.

OPERATION:

The processor board connects to an acquisition board specific to the I/O pack function. Upon application of input power, the soft-start circuit ramps up the voltage available on the processor board. The local power supplies are sequenced on, and the processor reset is removed. The processor completes self-test routines and then loads application code specific to the I/O pack type from flash memory. The application code reads board ID information to ensure the correct matching of the application code, the acquisition board, and the terminal board. With a good match, the processor attempts to establish Ethernet communications, starting with a request of a network address. The address request uses the industry standard dynamic host configuration protocol (DHCP) and the unique identification read from the terminal board. After Ethernet initialization, the processor programs the on-board logic, runs the application, and enables the acquisition board to begin operation.

• High-speed processor with RAM and flash memory
• Two fully independent 10/100 Ethernet ports with connectors
• Hardware watchdog timer and reset circuit
• Internal I/O pack temperature sensor
• Infrared serial communications port
• Status-indication LEDs
• Electronic ID and the ability to read IDs on other boards
• Substantial programmable logic supporting the acquisition board
• Input power connector with soft start/current limiter
• Local power supplies, including sequencing and monitoring

PROFIBUS DP MASTER GATEWAY PROTOCOL BRIDGE

The PPRF's COM-C module, built on a PROFIBUS core based on Siemens ASPC2 technology, contains firmware that implements the PROFIBUS DP (Decentralized Periphery) functionality. Though the COM-C module is DPV1 capable, the PPRF only provides the basic DPV0 functionality, which includes configuring slave devices, cyclically exchanging I/O data with them, and obtaining PROFIBUS diagnostics. Memory is released as part of the PPRF necessary (for instance, when the PPRF firmware is released with an updated COM-C firmware).

FREQUENTLY ASKED QUESTIONS:

What is the IS220PPRFH1A Rev D?

It is a General Electric (GE) PROFIBUS Master Gateway (PPRF) I/O Module designed for Mark VIe Distributed control systems. It functions as a PROFIBUS DPV0 Class 1 master, enabling communication between PROFIBUS slave devices and Mark VIe controllers over the I/O Ethernet network.

What communication interface is used for PROFIBUS connectivity?

The module uses an integrated Hilscher COM-C communication module with a DE-9 (DB9) D-sub RS-485 connector to provide PROFIBUS DP master communication.

What PROFIBUS transmission speeds are supported?

It supports auto-negotiated PROFIBUS communication speeds ranging from 9.6 KBaud to 12 MBaud, ensuring compatibility with a wide range of PROFIBUS DP devices.

How much process data can be exchanged with each PROFIBUS slave device?

The module supports up to 244 bytes of input data and 244 bytes of output data per PROFIBUS slave, enabling efficient cyclic data exchange between the controller and field devices.

How is communication established with the Mark VIe control system?

After power-up and self-diagnostics, the module requests an IP address using DHCP, establishes communication through its dual 10/100BaseTX Ethernet (IONet) ports, loads the application firmware, and begins exchanging I/O data with the controller.

How does the hot-backup redundancy mode work?

In a hot-backup configuration, one gateway operates as the active PROFIBUS master while the second remains in standby mode. If the active unit fails, the standby unit automatically takes over, ensuring continuous communication with PROFIBUS slave devices.
