C.6 RS-485/RF I/O Channel Converter

The RS-485/RF (Coaxial) I/O Channel Converter, PPX:505–6860, allows you

to use coaxial cables in a Series 505 system, thereby extending the

maximum cable distance to 4 km. The converter connects a Series 505

RS-485 remote I/O interface to an RF remote I/O interface, and makes it

possible to go from a Series 505 local base either to a Series 500 remote base

that has RF media or to a dual media remote base.

For more information about using dual media with Series 505 remote bases,

refer to the SIMATIC 505 Redundant I/O Systems User Manual,

PPX:505–8125–x.

Your RBC must have firmware Rel. 3.0 or later if you use either the dual

media option or PCS 3.0 or later.

The RS-485/RF I/O channel converter is compatible with the following

CPUs:

• 545–1104 and 545–1106 CPUs

• 555–1103, 555–1104, 555–1105, and 5550–1106 CPUs

• 575–2104, 575–2105, and 575–2106 CPUs with installed PPX:575–2126

annex card.

NOTE: The RS-485/RF I/O channel converter is compatible only with RBCs

using the Series 505 remote I/O channel and Series 505/Series 500 remote

I/O, such as the PPX:505–6850–A and PPX:500–2114–A RF, dual-media-

compatible RBCs. The converter is not compatible with the 505

PROFIBUS-DP RBC or other products that use the PROFIBUS-DP I/O

channel.
