Description
ABB MPRCO86444-005 Industrial Ethernet
Ethernet for MPRCO 86444-005 is a local area network. The early standard was IEEE 802.3, using CSMA/CD for the data link layer, 10Mb/s speed Physical layer has:
(1) 10 Base 5 thick coaxial cable, RG-8, a section up to 500m long.
(2) 10 Base 2 thin coaxial cable, RG-58, one section up to 185m.
(3) 10 Base T twisted pair cable, UTP or STP, a section of up to 100m.
MPRCO86444-005 is compatible with IEEE802.3, so logically the commercial network and industrial network can be regarded as one Ethernet, and users can flexibly assemble their own network components according to the site conditions. However, from the harshness of the industrial environment and anti-interference requirements, the designer wants to use the Ethernet chips and media that can be found on the market, taking into account the following special requirements of the industrial site: first of all, high temperature, humidity, vibration.
