GE IS220PPRFH1B Mark VIe I/O Module

Description

The GE IS220PPRFH1B Mark VIe input/output module is a PROFIBUS gateway I/O module developed by GE under the Mark VIe series. The following is a detailed analysis of the module:

1、 Product Overview
Model: IS220PPRFH1B
Manufacturer: GE (General Electric)
Series: Mark VIe
Type: PROFIBUS main gateway I/O module
2、 Main functions
The IS220PPRFH1B module is a PROFIBUS DPV0 Class 1 master device, whose main function is to map the Mark VIe controller on the I/O Ethernet to the I/O from PROFIBUS slave devices. This module communicates with slave devices through the PROFIBUS DP (Distributed Peripheral Device) protocol to exchange and control data.

3、 Technical specifications
PROFIBUS connection:
Interface: DE-9 D-sub RS-485 interface
Number of supported slaves: 125 slaves, each capable of processing 255 bytes of input and output.
Transmission rate: from 9.6 KBaud to 12 MBaud.
I/O throughput:
Half Boolean and half analog, with a total of 500 inputs and 500 outputs.
Frame rate: 40 ms (this is a requirement, not a hard limit).
Power requirements:
Power supply rated range: 27.4-28.6 V DC.
Input voltage nominal: 28Vdc.
Environmental adaptability:
Environmental temperature level: -20 to+55 ° C (-4 to+131 ° F).
Certification: may include ATEX Zone 2, IIC group certification, etc. (specific certification information may vary by product batch and region).
4、 Module structure
The IS220PPRFH1B module includes a processor board shared by all Mark VIe distributed I/O modules and an acquisition carrier board equipped with a COM-C PROFIBUS communication module provided by Hilscher GmbH. The processor board and the acquisition carrier board are connected in a specific way to achieve data acquisition and processing.

5、 Operation and self inspection
When input power is applied, the soft start circuit will increase the available voltage on the processor board.
The processor is reset and turned off, and the local power is turned on in sequence.
After completing the self-test routine, the processor loads application code specific to the I/O pack or module type from flash memory.
The application code reads the board ID information to verify whether the application code, acquisition board, and terminal board are correctly matched.
6、 Application scenarios
The IS220PPRFH1B module is commonly used in industrial automation systems that require PROFIBUS communication, especially in control systems for equipment such as gas turbines and wind turbines. It can achieve seamless connection with various slave devices, improving the overall performance and reliability of the system.
