Which is faster....Bluehose vs. Analog?
Which is faster....Bluehose vs. Analog?
(OP)
We are trying to upgrade the monitoring of our new system. The Vendor supposedly has made it possible to retrieve all of the data via "bluehose". I notice many of the signals that we want are also wired out to analog outputs. It certainly looks like we can get more info from the bluehose. We have a screen in our control room that displays important infor.
I say supposedly because I don't understand how you extract the info from the bluehose. I'm not a programmer.

The 'screen' in your control room can not handle analog data (nor can anyone else's), the HMI panel can only handle digital data.
Presumably both your PLC and the HMI panel screen 'speak' DH or DH+ or some other digital protocol that runs over bluehose cable.

If you need faster, and assuming you have an AB PLC5 (by virtue of someone suggesting "Blue Hose"), you may want to consider upgrading your comm modules to Ethernet IP. But first determine what you really need. Assuming faster is better is often a great way to waste money...

BTW DH+ is RS-485, but DH+ can go up to 230 kbaud. Profibus-DP which is also RS-485 can go up to 12 mbaud.
