A standard RS 485 PROFIBUS repeater module for 12 Mbps with diagnostic LEDs and a redundancy feature
The Anybus 2 Channel Repeater is a standard RS 485 PROFIBUS repeater module for 12 Mbps with diagnostic LEDs and a redundancy feature. Bus connection is utilised by screw terminals and additional DB9 connectors.
The repeater channels are directly connected with the ProfiTrace OE core in the 1B/1C Head Station. Bus monitor data is directly available on the web server.
The advanced 12 Mbps core of the repeater module can be cascaded unlimitedly and has increased RS 485 strength. The data traffic is constantly monitored for glitches which are digitally filtered out. Every channel has onboard switchable termination and is able to drive 31 devices.

| Cascading units |
With standard bus parameters: At baudrate Normal mode[units] 9.6 kbps 7 19.2 kbps 7 45.45 kbps 42 93.75 kbps 7 187.5 kbps 7 500 kbps 17 1.5 Mbps 23 3 Mbps 19 6 Mbps 16 12 Mbps 15 Formula to calculate a number of cascading units with adjusted Tslot : Cascading units = (Tslot – maxTsdr) / (2 × Tdata_delay_time) Tdata_delay_time is described in protocol specifications on the previous page. Example 1.5 Mbps, normal mode: Cascading units = (300-150) / (2×3.2) = 23 |
