Posted 21 Oct 2022 I have a 1747-L30B SLC Brick and it is set to load from EEPROM on boot S:5/8, Error S:1/10, and Run S:1/12. I need to make changes to the program and then store it to EEPROM via "Comms>EEPROM>Store to EEPROM." When I attempt to store the program with changes, it displays the message "Insufficient Memory Module Size." I assumed the EEPROM memory was maxed out, but I also uploaded the existing program currently stored to EEPROM, made no changes, and attempted storing it back to EEPROM and received the same message. Any advice? Share this post Link to post Share on other sites
Posted 21 Oct 2022 Maybe the error is bogus, but something else. Is there a read-only or read-write physical jumper? Share this post Link to post Share on other sites
Posted 25 Oct 2022 If there is a jumper, I haven't located it. I looked over the 1747-L30 Installation and Operation Manual and did not see any reference to a jumper for read-write functions. Share this post Link to post Share on other sites
Posted 25 Oct 2022 Have you checked into this technote? https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/15983/loc/en_US Firmware Versions and EEPROM Versions seem to be tricky. Some eeproms will read to load but not store. 1 person likes this Share this post Link to post Share on other sites
