Page 7: Chapter 1. Description
I/O modules compatible with programmable controllers from Siemens® and CTI. The 2500C-RBC-RS485 RS485 Remote Base Controller (RBC) allows a 2500 Series® Compact I/O base to function as a remote base. It provides the following functions: Compatible with CTI 2500 Series® and Simatic®... -
Page 8: Serial Port
1.2.1 Serial Port The RS232 port is provided to interface to PLC programming and configuration tools such as TISOFT . A standard 9-pin PC-compatible RS232 serial cable is used to connect to the programming device or modem. The port pinout is provided in Section 2.6 of this manual. 1.2.2 I/O Port The I/O Port connects the 2500C-RBC-RS485 to a SIMATIC®... -

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 2.1.3... -

Page 12: Configuring The Module
Configuring the Module There are three steps to configuring the module and making it fully operational: 1. Setting the RS232 Port baud rate 2. Setting the Remote Base Controller address 3. Setting the output state on communication loss (Freeze Jumper) Figure 2. -
Page 13: Setting The Output State On Communication Loss
2.5.2 Setting the Output State on Communication Loss When I/O channel communication to a remote base is lost, the state of the discrete outputs is determined Figure 5. 2500C-RBC- by the selection made on the 2500C-RBC-RS485 jumper JP4 (Off/Freeze). RS485 Freeze Jumper Selection Jumper shows the location of the jumper on the 2500C-RBC-RS485. -
Page 14: Setting The Remote Controller Base Station Address
I/O station identification. A maximum of 15 remote bases can be connected to the CTI 2500 Series® CPU or Siemens® 545/555/575 CPU. NOTE: When connecting the 2500C-RBC-RS485 to a CTI 2500 Series® CPU or Siemens® 545/555/575 CPU, only addresses between 1 and 15 are valid. Each installed 2500C-RBC- RS485 must have a unique station number. -
Page 15: Connecting To The Rs232 Port
Connecting the Remote I/O Cable The I/O Port connects the 2500C-RBC-RS485 to a SIMATIC® 505 compatible RS485 Remote I/O channel. This enables the remote CTI 2500 Series® or Simatic® 505® CPU to control the I/O modules in the base where the RBC is located. -

A. 5. Cable Routing and Layout Guidelines Cables containing the following should be routed Bus signals, e.g. Remote I/O Data signals for PCs, programming devices, printers etc. Screened analog inputs Unscreened DC voltages (<= 60V) in the same cable loom or cable duct Screened process signals (<= 25 V) Unscreened AC voltages (<= 25V) Coaxial cables for monitors... - Page 23 Appendix B. The 2500C-RBC-RS485 Remote Base Controller is designed to place the I/O on its base into ilures involving the PLC processor and communications cabling. The safe state for the I/O depends on the setting of the FREEZE jumper (see 2.5.2 Setting the Output State on Communication Loss). The following situations will cause the outputs go to the safe state: 1.
