IS220PPRFH1B GE发那科主网关 I/O 模块

IS220PPRFH1B 特点：

PROFIBUS RS-485 接口由 COM-C 模块通过 DE-9 D-sub 插座连接器提供。它用作 PROFIBUS DP 主站，最多支持 125 个从站，具有 244 字节的输入和输出，每个从站的传输速率从 9.6 KBaud 到 12 MBaud。

PPRF 支持以下冗余选项：单个 I/O 包的单个 I/O 以太网连接(无冗余)；一个 I/O 包，带有两个用于 I/O 的以太网连接；带有两个端口的热备份以太网连接；

其他 IO 包共享双 I/O 以太网连接设计。但是，在热备份系统中使用了两个 PPRF，其中一个是主动的，通过 PROFIBUS 与从设备连接，另一个是被动的，处于待机模式，准备在主动主故障的情况下接管。

IS220PPRFH1B Features:

The PROFIBUS RS-485 interface is provided by the COM-C module via the DE-9 D-sub socket connector. It functions as a PROFIBUS DP master, supporting up to 125 slave stations with 244 bytes of input and output, each slave with a transfer rate from 9.6 KBaud to 12 MBaud.

PPRF supports the following redundancy options: a single I/O Ethernet connection for a single I/O packet (without redundancy); One I/O packet with two Ethernet connections for I/O; Hot backup Ethernet connection with two ports;

Other IO packages share a dual I/O Ethernet connection design. However, two PPRFS are used in a hot backup system, one of which is active, connected to the slave device via PROFIBUS, and the other is passive, in standby mode, ready to take over in case of active master failure.
