Re: [foxboro] Mac Address


Thanx For prompt reply.

                            But still more detail can I get such that 6C in
Mac address means FoxBoro Module ,  6CC0 in Mac address means FT Module ,
08xxxxx means 50/51 series module , 02xxxxx means PW station like that.

MAC addresses are the fundamental addressing mechanism in any Ethernet
based
LAN.

Each Ethernet chip manufacturer is given a range of MAC addresses that they
may build into their E'net chips.

MAC addresses are unique. In the entire world, no two chips are to have the
same MAC address.


In the I/A Series, we override the MAC of our FT stations so that each
station has the same address. SysDef ensures that no two stations in the
same control system have the same MAC address.

Since the MAC addresses are the same both members of an FT pair get the
same
messages from other stations. This is required for FT to work.

Hope this helps.
