BradCommunications
SNMP MS is a comprehensive suite of tools used to display and analyze
SNMP diagnostic data from Ethernet networks. SNMP tags can be
transmitted through a switch, such as a BradCommunications Direct-Link
Industrial Ethernet managed switch, to an HMI display where they can be
easily displayed through the use of the SNMP MS. Non-Ethernet experts
can quickly and easily view any problems including status of individual
ports, bandwidth utilization and network error rates. This
information decreases downtime, allows traffic use to be analyzed,
helps pinpoint bottlenecks, and lets users take corrective actions
including the redistribution of devices on the Ethernet network. This
system comes in Basic, Expert and Enterprise editions.
DeviceNet
Doctor is a passive device that continuously monitors a DeviceNet
network and stores the information as OPC status tags on an HMI display
residing on Ethernet. This device provides accurate measurements of
network parameters using high-speed sampling. By storing a baseline
measurement of a “good” network, it can predict imminent failures on
individual devices. Data can be stored to historian software for future
analysis.
