产品内容介绍
A-B 8510-AA22-B2模拟量伺服控制器
ControlLogix控制器–说明图36和图37中的数据结构使用32位字，可以在一条消息中最多可容纳32个参数。在响应消息中，设置了位15的参数编号表示相关参数值字段包含错误代码（响应数据中的参数编号将为负数）。
PowerFlex 750系列交流驱动器编程手册，出版物750-PM001列出了每个参数的数据类型。执行散射时读取REAL数据类型参数，响应中的DINT参数（目标数据）数组需要COP到REAL标记。驱动器处于固件升级模式。
选项模块存在EEPROM故障。
网络地址开关在通电后已更改。
检测到重复的IP地址故障。DHCP租约已过期。
网络地址开关设置为“888”
网络配置（IP地址、子网掩码、网关地址）无效。用户FPGA配置无效。
查看选项模块事件队列以确定这些条件中的哪些是目前然后，根据原因，采取适当的纠正措施。
•清除选项模块中的故障。
•循环驱动电源。
•如果循环电源不能解决问题，则选项模块参数
设置可能已损坏。重置默认值并重新配置选项单元
•如果重置默认值不能解决问题，请更新选项模块具有最新固件版本。
•将网络地址开关更改为“888”以外的值。纠正措施
关闭选项模块未通电。
选项模块未正确连接到网络。
选项模块尚未获取其网络配置（IP地址、子网掩码、网关地址）服务器
•将选件模块完全连接并接地至驱动器
将其插入驱动器端口，并将其两个外加螺钉拧紧至建议扭矩。
•将以太网电缆正确连接到以太网连接器。
•使用选项模块旋转开关设置唯一的IP地址，选项模块参数，或BOOTP或DHCP服务器。
•给驱动器通电。
红色闪烁I/O连接超时。•将控制器置于RUN模式，或向对等设备通电发送I/O。
•检查IGMP侦听/以太网交换机是否正常工作。
•检查网络流量。
稳定红色检测到重复的IP地址故障。DHCP租约已过期。配置选项模块以使用唯一的IP地址并循环电源。
绿色闪烁选项模块工作正常，但没有CIP连接（I/O或显式）。
•将控制器置于RUN模式，或向对等设备通电发送I/O。
•对控制器或对等设备进行编程，以识别和传输I/O，或与选项模块的消息连接。
•为控制器或I/O中的程序配置选项模块来自对等设备。
ControlLogix Controller – Explanation
The data structures in Figure 36 and Figure 37 use 32-bit words and can accommodate up to 32 parameters in a single message. In the Response Message, a parameter number with Bit 15 set indicates that the associated parameter value field contains an error code (parameter number in response data will be negative). The PowerFlex 750-Series AC Drives Programming Manual, publication 750-PM001, lists the data type for each parameter. When performing a Scattered Read of REAL data type parameters, the DINT parameter value in the Response (Destination Data) array will need to be COP to a REAL tag.The drive is in firmware upgrade mode. The option module has an EEPROM fault. The network address switches have been changed since powerup. A duplicate IP address fault has been detected. The DHCP lease has expired. The network address switches are set to “888.” The network configuration (IP address, subnet mask, gateway address) is invalid. The User FPGA configuration is invalid. View the option module event queue to determine which of these conditions is present. Then, depending on the cause, take the appropriate corrective action. • Clear faults in the option module. • Cycle power to the drive. • If cycling power does not correct the problem, the option module parameter settings may have been corrupted. Reset defaults and reconfigure the option module. • If resetting defaults does not correct the problem, update the option module with the latest firmware revision. • Change the network address switches to a value other than “888.”
Corrective Actions Off
The option module is not powered. The option module is not properly connected to the network. The option module has not acquired its network configuration (IP address, subnet mask, gateway address) from the BOOTP/DHCP server. • Securely connect and ground the option module to the drive by fully inserting it into the drive port and tightening its two captive screws to the recommended torque. • Correctly connect the Ethernet cable to the Ethernet connector. • Set a unique IP address with the option module rotary switches, option module parameters, or a BOOTP or DHCP server. • Apply power to the drive. Flashing Red The I/O connection has timed out. • Place the controller in RUN mode, or apply power to the peer device that will send I/O. • Check the IGMP Snooping/Ethernet Switches for correct operation. • Check the amount of traffic on the network. Steady Red A duplicate IP address fault has been detected. The DHCP lease has expired. Configure the option module to use a unique IP address and cycle power. Flashing Green The option module is operating normally, but does not have any CIP connections (I/O or explicit). • Place the controller in RUN mode, or apply power to the peer device that will send I/O. • Program the controller or peer device to recognize and transmit I/O, or make a message connection to the option module. • Configure the option module for the program in the controller or the I/O from the peer device.
