FAQ Question?What is the significance of the “Series F” and “FW 11” on this 1747-L532 processor?Answer: The “Series F” denotes a specific hardware revision, which can be important for compatibility with certain I/O modules or chassis. “FW 11” refers to the OS firmware version 11. This is critical as programs created with newer software versions might not be compatible, and specific communication features or instruction sets are tied to the firmware level. Question?Can this SLC 5/03 CPU communicate over EtherNet/IP?Answer: No, not natively. The 1747-L532 processor comes with built-in DH-485 and RS-232 serial ports. To connect it to an EtherNet/IP network, you would need an external gateway module, such as a 1761-NET-ENI, which converts the serial communication to EtherNet/IP. Question?What type of battery does the 1747-L532 use for memory backup, and when should it be replaced?Answer: The 1747-L532 uses a 3V lithium battery, part number 1747-BA. The “BATT” LED on the front will illuminate when the battery voltage is low. It is crucial to replace the battery while the processor is powered on to prevent the loss of the user program stored in the RAM. It is recommended to replace it every 1-2 years as part of a preventative maintenance schedule.
