产品详细资料
LAN接口状态位监测以太网接口本身的运行状况,例如LAN接口OK位。通道状态位监视通道的运行状况。每个Modbus通道都有一个专用的状态位。有关状态位及其操作的详细信息,请参阅2.6节,监测以太网接口状态位。10.5.1.2 COMMREQ功能块的FT输出如果COMMREQ函数块本身存在编程错误、COMMREQ SYSID参数中指定的机架和插槽未配置为包含以太网接口,或者命令块中指定的数据块长度超出范围,则设置该输出。该输出也可能表明,在以太网接口有时间处理一些未决COMMREQ函数之前,梯形图程序中不能再启动COMMREQ功能。如果设置了FT输出,则CPU不会将命令块传输到以太网接口。在这种情况下,其他状态指示器不会为此COMMREQ更新。FT输出在出现以下错误时传递功率:▪ 指定的机架/插槽无效。此机架/插槽上的模块无法接收COMMREQ。▪ 无效的任务ID。▪ 无效的数据块长度(零或大于128)。▪ 同时激活的COMMREQ过多(PLC CPU或以太网接口过载)。
The LAN interface Status bits monitor the health of the Ethernet interface itself, such as the LAN interface OK bit. The Channel Status bits monitor the health of a channel. Each Modbus channel has a dedicated status bit. For details of the status bits and their operation, refer to Section 12.6, Monitoring the Ethernet Interface Status Bits. 10.5.1.2 FT Output of the COMMREQ Function Block This output is set if there is a programming error in the COMMREQ Function Block itself, if the rack and slot specified in the COMMREQ SYSID parameter is not configured to contain an Ethernet interface, or if the data block length specified in the Command Block is out of range. This output also may indicate that no more COMMREQ functions can be initiated in the ladder program until the Ethernet interface has time to process some of the pending COMMREQ functions. If the FT Output is set, the CPU does not transfer the Command Block to the Ethernet interface. In this case, the other status indicators are not updated for this COMMREQ. The FT Output passes power upon the following errors: ▪ Invalid rack/slot specified. The module at this rack/slot is unable to receive a COMMREQ. ▪ Invalid Task ID. ▪ Invalid Data Block length (zero or greater than 128). ▪ Too many simultaneous active COMMREQs (overloading either the PLC CPU or the Ethernet interface).
