7 Repeater modules (RS-485)
The standard RS-485 PROFIBUS repeater modules can be a 1 or 2
channel type. Suitable for 12 Mbps with screw terminals,
additional DB9 connector, onboard termination, diagnostic LEDs
and redundancy feature.
The advanced 12 Mbps core of the repeater module is identical as
the ProfiHub and repeater B1; it can be cascaded unlimitedly and
has increased RS-485 strength. It does not have the frustrating
short-circuit bug and the bus communication is constantly
monitored for glitches which are digitally filtered out. Every
channel has on-board switchable termination and is able to drive
31 devices.
The repeater channels are directly connected with the ProfiTrace
OE core in the 1B/1C Head Station. Busmonitor data is directly available in the web server.
10 Repeater modules can be inserted in the backplane. This is independent of the amount of
channels on the repeater modules.
This chapter does not apply to the characteristics of the RS-485-IS Barrier module. It has been listed
for comparison purposes only. For a detailed description of the RS-485-IS Barrier module, refer to
chapter 8.
