Smoke Posted December 12, 2006 Report Posted December 12, 2006 I have some 351 CPU with Rev. 7.01 I need to expand the memory. Can I upgrade the Rev. to 9.01 and if so will I have the memory expansion option.
Steve Bailey Posted December 13, 2006 Report Posted December 13, 2006 The CPU351 has firmware in flash, so you can upgrade to the highest level available. Remember that the highest available revision level for the CPU351 is not the same as for the 36x and 37x CPUs. I believe the CPU351 has always had 240K memory. Are you confusing the version of the CPU351 firmware with the revision level of Logicmaster software necessary to take advantage of it?
Smoke Posted December 13, 2006 Author Report Posted December 13, 2006 You are correct Steve I was confusing the firmware with the revision level of Logicmaster software. The current LogicMaster software rev I an using is 9.05. but when I connect to the 351 CPU It is 7.01. If I make a logic change is the PLC will the rev change to 9.05 and can I increase the registers.
