Could someone help me with a procedure to change out a 32 bit SLC 5/05 to a 64 bit SLC 5/05 processor ? I am new to the process. The manual is confusing at first glance with so many different options for configuration. The processor is connected on ethernet. I figure, I upload the exisiting program to my laptop, power down the chassis, replace the processor, power up the new processor, set-up the channel 1 configuration I.P. address, subnet, gateway, establish communication and upload the program. Am I correct here or am I totally off base. If someone could give me a procedure I'd really appreciate it. Thanks alot and your forum is great and very informative. Cheers
