PLC逻辑程序应在短暂延迟后重试COMMREQ。如果这种情况持续存在,则应修改逻辑应用程序,以降低其向以太网接口发送COMMREQ的速率。非关键CPU软件事件CPU试图发送邮件消息的速度快于以太网接口检索到的速度;消息被丢弃。这可能会导致随后的“背板通信与控制器故障;请求丢失”故障。监控以太网接口状态位以太网接口状态比特占用单个内存块,这是在配置以太网接口时指定的。以太网接口在每次控制器扫描时更新CPU中的状态位。当某些错误发生时,这些位可用于防止COMMREQ函数的启动,或在已建立的信道上发出问题信号。该块的前16位是LAN接口状态(LIS)位。接下来的64位是通道状态位(每个通道2个)。如果LAN接口OK位(位16)未设置,则其他状态位无效。1端口1A全双工端口1全双工端口全双工端口LAN1保留在此处,以与其他CPE兼容。2端口1A 100 Mbps端口1 100 Mbps以高支持速度运行的端口以高支持速率运行的端口LAN1保留在此处以与其他CPE兼容。
The PLC logic program should retry the COMMREQ after a short delay. If the condition persists, the logic application should be revised to reduce the rate at which it sends COMMREQs to the Ethernet interface. Non-critical CPU software event The CPU is attempting to send mail messages faster than they can be retrieved by the Ethernet interface; the messages are discarded. This can result in subsequent “Backplane communications with controller fault; lost request” faults.Monitoring the Ethernet Interface Status Bits The Ethernet Interface status bits occupy a single block of memory, which is specified when the Ethernet Interface is configured. The Ethernet Interface updates the status bits in the CPU once each controller scan. These bits can be used to prevent initiation of a COMMREQ function when certain errors occur or to signal a problem on an established channel. The first 16 bits of the block are the LAN Interface Status (LIS) bits. The next 64 bits are Channel Status bits (2 for each channel). If the LAN Interface OK bit (bit 16) is not set, the other status bits are invalid.1 Port 1A full-duplex Port 1 full-duplex Port full-duplex Port full-duplex LAN1 stays here for compatibility with other CPEs. 2 Port 1A 100 Mbps Port 1 100 Mbps Port operating at highest supported speed Port operating at highest supported speed LAN1 stays here for compatibility with other CPEs.
