Page 7: Chapter 1. Description
Siemens® and CTI. The 2500-RIO-B RS485 Remote Base Controller (RBC) allows a 2500 Series® I/O base to function as a remote base. The 2500-RIO-B is intended to be a replacement for the Siemens® 505-6851-A RBC. It provides the following functions: ... -
Page 8: Communication Ports
Appendix A. 1.3. Dual-Media and Hardware Redundancy Installations A pair of 2500-RIO-B RBC’s may be installed in a 2500-R11-A or 505-6511 redundant base to provide dual media as well as hardware redundancy. In a redundant configuration, two 2500-RIO-B units are installed in the base and separate cable runs are used to provide redundancy in both the hardware and communications cabling between the CPU and the remote base. -

Before proceeding, you must determine what address you will assign to the RBC. Remote Base addresses range from 1 to 15. In CTI 2500 Series® and Simatic® 505® systems, address 0 is reserved for the local base where the CPU is installed. Note that each Remote Base on the Remote I/O channel must have a unique address. -

I/O base. CAUTION: The components on the 2500-RIO-B module printed circuit card can be damaged by static electricity discharge. To prevent this damage, the module is shipped in a special anti-static bag. Static control precautions should be followed when removing the module from the bag and when handling the printed circuit card during configuration. -

Page 23: Laying Cables Outside Of Control Cabinets
If this cannot be avoided, additional protective measures should be taken, such as laying the cables in a steel pipe or rugged metal duct. The pipe or duct should then be grounded at regular intervals and protected against corrosion. CTI 2500-RIO-B Installation and Operation Guide V1.4... -
Page 24: Appendix B. I/O "Safe State" Operation
APPENDIX B. I/O “SAFE STATE” OPERATION The 2500-RIO-B Remote Base Controller is designed to place the I/O on its base into a “safe state” on the occurrence of various kinds of system failures involving the PLC processor and communications cabling. The safe state for the I/O depends on the setting of the FREEZE jumper (see Section 2.4). -
