IS220PPRFH1A GE Mark VIe, Profibus PPRF Pack

Description:

IS220PPRFH1A is a PROFIBUS Master Gateway pack developed by GE. The PROFIBUS Master Gateway (PPRF) pack is a PROFIBUS DPV0, Class 1 master that maps I/O from PROFIBUS slave devices to I/O Ethernet Mark VIe controllers. The module includes a processor board shared by all Mark VIe distributed I/O modules and an acquisition carrier board outfitted with a Hilscher GmbH COM-C PROFIBUS communication module.

A PROFIBUS RS-485 interface is provided by the COM-C module via a DE-9 D-sub receptacle connector. It functions as a PROFIBUS DP master, with transmission rates ranging from 9.6 KBaud to 12 MBaud and up to 125 slaves, each with 244 bytes of inputs and outputs.
Other IO packs use the same dual I/O Ethernet connection configuration. In the hot-backup mode, however, two PPRFs are used, one as the active PROFIBUS master communicating with slave devices and the other in a passive, stand-by mode, ready to become the active master in the event of an active master failure.
The following redundancy options are supported by the PPRF:
-One I/O pack with one Ethernet connection (no redundancy)
-Dual I/O Ethernet connections on a single I/O pack
-Dual I/O Ethernet connections on the hot-backup I/O pack

The PROFIBUS Master Gateway Terminal board (SPIDG1A) is used to install the PPRF and provide an electronic ID. Its only connection is to the PPRF, as the PROFIBUS connection is made to the DE-9 D-sub receptacle connector exposed on the PPRF's side. On the PPRF, indicator LEDs provide visual diagnostics.
The number of I/O packs used in a signal path is referred to as the control mode:
-Simplex employs a single I/O pack and one or two network connections.
-Hot backup employs two I/O packs, each with two network connections.
