Roth Posted December 4, 2007 Report Posted December 4, 2007 We have an A1S-S1 CPU and an 8K EPROM. We need to carry out a mod to the PLC code. How can we download to PLC memory and also to the EPROM to ensure that the new code operates even after power loss. We are using GX dereloper Ver 8 to modify the code.
Gambit Posted December 5, 2007 Report Posted December 5, 2007 Check if you have the EPROM or EEPROM. If it's a EEPROM you can just upload, download & verify from GX DEV as you would do normally. If It's an EPROM you will need a A6WA-28P The EPROM is called A1SNMCA-8KP The EEPROM is called A1SNMCA-8KE
