Biesse Rover 346 Retrofit

Are you sure?,A Mesa 7i66 is rated at more than twice the current of your old boxes (2.5A vs 700mA)

You're right, 7i66 would do the job.

I didn't pay attention to this card, and it would have been easier to start from here...

I think I'll go that way, replacing CNI modules by 7i66 cards.

For more IO there is the 7i64 too. (The 7I64 provides 24 isolated 48VDC 2.5A output drivers and 24 x 24V inputs)

Serial control might be fun, but the Mesa card UART is 8-bit. (There is n-bit SPI, though)

Are the serial IO cards p260? I might have what you are looking for. Let me know. Thanks.

Hi pmcstoneinc!
I have some p260 cards and a chinese usb/rs485. I would like to use those cards but I have no driver or communication protocol. Could you share your solution?

Thanks

You can use those modules and solder wires onto the relays and not use the rs485 comm stuff. The advantage is they have snubber circuits on them already and some of the solenoids on these machines have alot of kickback voltage spikes. I froze my 7i77 board like this and needed a restart to recover from it.

I also have access to a spectrum analyzer, and decided not to go down that route as it would be too long a delay, and besides my machine is a 1995 and they started the rs485 relay/input modules in 1996 or 1997. It sure would make it easier for retrofitting these machines if it were done...... Retrofitting would be a breeze with these modules.

Does your machine have tool changer and how many spindles? 3?

Let me know if you need help, I just finished a Rover 346 with mesa cards.

Get a 7i74 and put remote 7i84's and/or 7i70/7i71 cards. You would just have to rn cat 5/6 cables from control panel to the locations of the modules.

just a thought.
