增强功能本节介绍此版本
固件中提供的增强功能。•改进了动态内存分配HEAP管理器，以消除由于网络负载过重或广播网络消息突发导致的潜在缓冲区溢出。•向EtherNet/IP UDP服务器添加了重试检测。•将最大服务数据大小从160字节增加到256字节，从而提高了数据缓冲容量。•添加了检测、忽略和正确排序丢失的I/O数据包的逻辑，当这些数据包被接收到时，这些数据包会出现故障。主题页增强功能1纠正异常2确定固件版本2固件闪烁4限制7兼容版本7自动化支持8产品满意度返回8自动化出版物20COME-RN003A-EN-P-2012年5月2 20-COMM-E EtherNet/IP适配器固件版本4.002纠正异常本节描述了此版本中纠正的异常固件。•当到驱动器的DPI连接出现问题时，EtherNet/IP UDP服务器出现异常。这导致RSLinx®在查看设备属性屏幕时显示设备的错误信息。确定固件版本本节描述了确定20-COMM-E EtherNet/IP适配器固件版本的步骤。

Enhancements This section describes this version
Enhancements provided in firmware. • The dynamic memory allocation HEAP manager has been improved to eliminate potential buffer overflow caused by heavy network load or broadcast network message burst. • Added retry detection to the EtherNet/IP UDP server. • Increase the maximum service data size from 160 bytes to 256 bytes, thereby increasing the data buffer capacity. • Added logic to detect, ignore, and correctly sort lost I/O packets. When these packets are received, they will fail.
