A-B 1756-L72 可编程自动化控制器

Allen-Bradley 1756-L72是ControlLogix系列可编程自动化控制器(PAC)。它有一个4 MB的用户内存用于数据和逻辑，还有0.98 MB的I/O内存。控制器配有一个1 GB的SD卡，1784-SD1，可以将它用作可选的非易失性存储器。如果存储空间不够用，还可以通过1784-SD2卡将其升级到2 GB。建议将SD卡安装到控制器上，并且只使用Rockwell Automation出售的sd卡，因为这些sd卡已经过充分测试，可与控制器配合使用。使用其他SD卡会带来数据丢失或损坏的风险。SD卡主要用于存储故障发生时自动写入的诊断数据。罗克韦尔自动化使用这些数据进行故障排除。

Allen-Bradley 1756-L72属于***的ControlLogix产品类别。该部件号代表ControlLogix控制器，具有4Mb用户内存和0.98 MB预分配I/O内存容量。1756-L7x控制器引入了多项升级。对于非易失性存储器，该控制器使用安全数字(SD)卡。默认情况下，该控制器配有1GB非易失性内存。此非易失性存储器的替换模块是1756-SD1和1756-SD2。此外，该控制器不使用电池。代替RS232通信端口，这种控制器具有USB通信端口，其功能类似于RS232，但是更稳定，并且不需要昂贵的通信电缆。如果需要，可以使用闪存实用工具升级或降级控制器的集成内存。

Allen Bradley 1756-L72 is a ControlLogix series programmable automation controller (PAC). It has 4 MB of user memory for data and logic, as well as 0.98 MB of I/O memory. The controller is equipped with a 1 GB SD card, 1784-SD1, which can be used as an optional non-volatile memory. If the storage space is not enough, you can also upgrade it to 2 GB using a 1784-SD2 card. It is recommended to install SD cards on the controller and only use SD cards sold by Rockwell Automation, as these SD cards have been fully tested and can be used in conjunction with the controller. The use of other SD cards poses a risk of data loss or damage. SD cards are mainly used to store diagnostic data that is automatically written when a fault occurs. Rockwell Automation uses this data for troubleshooting.

Allen Bradley 1756-L72 belongs to the latest ControlLogix product category. This part number represents the ControlLogix controller, which has 4Mb of user memory and 0.98 MB of pre allocated I/O memory capacity. The 1756-L7x controller has introduced multiple upgrades. For non volatile memory, this controller uses a Secure Digital (SD) card. By default, this controller comes with 1GB of non volatile memory. The replacement modules for this non-volatile memory are 1756-SD1 and 1756-SD2. In addition, the controller does not use batteries. Instead of RS232 communication port, this controller has a USB communication port, which functions similar to RS232 but is more stable and does not require expensive communication cables. If necessary, the integrated memory of the controller can be upgraded or downgraded using the flash utility.
