CHAPTER 1. DESCRIPTION
1.1. Introduction
The CTI 2500-RIO-B RS485 Remote Base Controller is
a member of Control Technology's family of I/O
modules compatible with programmable controllers
from 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:
Compatible with CTI 2500 Series® and
Simatic® 505® CPUs.
Can be used in currently-available CTI and
Siemens® 4, 8, 11, and 16-slot bases
Supports communication speeds 1Mbits/sec and
maximum cable distance of 1000 meters
LED display which shows error and status codes
Front panel thumbwheel switch for setting the
station address
On-board RS232 port which can be used for
PLC programming and configuration.
The 2500-RIO-B resides in 2500 Series® base. It
installs in the second slot from the left, adjacent to the
power supply module. When used in a 2500-R11-A
Redundant Base, two 2500-RIO-B units can be installed
in the third and fourth slots from the left, adjacent to the
second power supply.
Do not install this module into a normal I/O slot, as damage can occur.
NOTE:
Immediate IO and Interrupt IO are not supported by the RS-485 Remote IO Network System.
