Guys, this is more of a theory question that Im trying to learn here. Any info or experiences would be great.
Have what is called a GEHO pump. This pump is controlled by Siemens S5 PLC. Comms is one way, out of the S5 to a Yokogawa DCS. The data is transmitted out of the S5 in RS232, it then gets converted to RS485 by an Adam 4520 converter module, then the RS485 cable goes into the DCS.
Is RS232 and RS485 actual comms protcols like Ehternet, DH+, Profibus?
If so, are they a non generic brand, like an industry standard type of thing?
How do I go about learning how a RS485 protocol works and why? Can any one post some good notes or a link to a good website?
Im very black box when it comes to networks, use them but not sure of the underlying stuff.
Cheers
