AZ1975 Posted September 23, 2011 Report Share Posted September 23, 2011 Hello, What PLC do you recommend for a Dairy Farm, about 200 I/O, few analogs, and maybe external HMI . Thanks, AZ1975 Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted September 26, 2011 MVP 2023 Report Share Posted September 26, 2011 A V570 is a good choice for a system this size, as it offers a local 5.7" color touchscreen and has a built-in CANbus port which you will probably need for the number of I/O you have. You can also look at the V1040 or the V1210 if you want a larger screen. You can use the second COM port to set it up as a Modbus slave for an external HMI. Joe T.

Damian Posted September 26, 2011 Report Share Posted September 26, 2011 I echo Joes suggestions. In addtion, having been involved with the same, I recommend sealing everything very well in enclosures. I would go Nema4X or IP equivalent on everything. The fumes from the cows can get very corrosive to electronics. Quote Link to comment Share on other sites More sharing options...
Cara Bereck Levy Posted September 26, 2011 Report Share Posted September 26, 2011 I would go Nema4X or IP equivalent on everything. The fumes from the cows can get very corrosive to electronics. Good suggestion. As a former dairymaid, I can attest to the generally corrosive elements of cow fumes Quote Link to comment Share on other sites More sharing options...
AZ1975 Posted September 26, 2011 Author Report Share Posted September 26, 2011 Thank you all for your tips. For sure the I/O will be placed inside an existing board. What about the PLC/PANEL ? I would like to place it "cut-out" at the same board as I/O. What do you think? thanks Quote Link to comment Share on other sites More sharing options...

MVP 2023 Joe Tauser Posted September 27, 2011 MVP 2023 Report Share Posted September 27, 2011 Oh.. Cara... be careful what you post about your past on the forum. This just screams for one of my photo-shopping projects . AZ - the front of the V570 will be fine in a corrosive environment as long as you use the gasket. I'd be more worried about getting cow poop all over the touchscreen. If this may be a problem, then you want to look at the V560 which has both a touchscreen and a full keypad with function keys. You build your screens so that the most of the common operations such as screen changing and data entry are tied to the function buttons. Joe T.
