Posted 24 Dec 2018 (edited) Dear Sir, Could you show me step by step to write a program to a memory cassette ( eg C200HW-ME08K). I tried many times but failed. Thank you very much. Edited 24 Dec 2018 by khoi Share this post Link to post Share on other sites
Posted 24 Dec 2018 It is an electrically erasable PROM - the program is written to battery backed RAM and then can be written to the EEPROM for backup purposes only. Read the manual. Share this post Link to post Share on other sites

Read the manual. Dear BobB, Sorry for my bad English. I want to back up an existing program to this EEPROM. Followings are my steps: 1. Turn off the Memory Protect switch of the EEPROM. 2.Open the program, switch off DIP2 of the PLC. 3. Power on the PLC, choose the Stop/Program mode. 4.Force SR270.00 to ON (value =1). 5. Download the program to PLC. 6. Power off the PLC. You can see the attached file ( written in Vietnamese) to get more info. Thank you very much.
