ComBricks PROFIBUS DP Monitoring Kit

The ComBricks PROFIBUS DP Monitoring kit is ideal for use behind existing 3rd party DP/PA couplers to provide 24/7 monitoring of your PROFIBUS DP network. With the ProfiTrace OE built into the ComBricks Head Station, this is an extremely powerful pro-active tool for remote monitoring over Ethernet. The kit does not require any changes to your PLC Master program, and it does not have a PROFIBUS address. It just “sniffs” the activity on your network and lets you monitor it remotely over the network.

This basic monitoring kit gives you the PROFIBUS live list, statistics and email/SNMP event notification. In addition, there is one relay on the Head Station that can be used to turn on a light tower, or a back-up system, etc. in response to network events such as station lost, syncs, etc. If more relays are needed, just snap in a 4 channel relay module!

The ComBricks DP monitoring kit can be installed mid-span on any segment in your network that has room for an additional bus load (in PROFIBUS DP each segment can have 32 bus loads). The kit can also be installed at the end of a segment and act as an Active Terminator! Active terminators are advised at the end of segments so the PROFIBUS DP Connector of the last device can be removed without losing termination. Note that PROFIBUS Terminators require power that comes from the device; so when the cable is removed from the last device to do service or maintenance, the termination is lost.

Snap in additional DP modules and monitor up to 4 networks from a single ComBricks system. There are simple dip switches on each module to assign it one of the four networks. The four networks can all be running at different speeds, for example 500 Kbps and 1.5 Mbps, and can even be running different protocols (MPI or PROFIBUS DP)!
