•
PROFIBUS
®
(29576)
– Non-powered two-wire (RS485) network, with up to 126 nodes, transferring a
maximum of 244 data bytes per node per cycle.
•
ETHERNET/IP (29873)
– Dynamic Host Configuration Protocol (DHCP) is used for address requests.
– The data is transmitted continuously from this module.
– The IP address may be made static by downloading the IP Configuration
Tool Software.
ETHERNET/IP can be easily confused as a simple combination of EtherNet and
the Internet Protocol. Instead, it is an Industrial Application Layer Protocol used
for communication between industrial control systems and their components.
– Such components include Programmable Automation Controller, Logic
Controller, or an I/O System.
The “IP” in EtherNet/IP is not an abbreviation for “Internet Protocol”, but instead, it
stands for “Industrial Protocol”.
