SYSTEM DESCRIPTIONS

■ GENERAL
The R5H Series Remote I/O consists of a power supply module, network interface module(s), I/O module(s) and a backplane (base). An extender base for an additional power supply module is available.
• Power Supply Module
Converts AC or DC power inputs for use in the network modules, I/O modules and for exciting discrete I/O.
• Communication Module
Converts data between the open network fieldbus (DeviceNet, etc.) and the internal communication bus, functioning as a Gateway between two buses.
• I/O Module
The model R5H-RS is a high accuracy 4-wire RTD input module. Performs A/D conversion of field analog inputs; D/A conversion of data received through the internal bus into analog/discrete outputs.
Temperature input is converted into signed binary data which equals 100 times its engineering unit value (°C). e.g. 25.53°C
is converted to 2553.
• Base
Backplane with communications and power supply buses.
An extender base is available for an additional power supply module for dual redundancy.
The R5-BS04, -BS08 and -BS16 can mount two network modules for dual redundant communication. Single mode is also usable.
The R5-BS05 and -BS09 can mount only one network module for single communication mode only.
■ SINGLE COMMUNICATION MODE
When the single communication mode is employed, the input modules send out via the internal bus analog inputs to the network module. The network module outputs the data to the field bus.
■ DUAL COMMUNICATION MODE
A dual redundant communication system can be easily achieved by employing two network modules and using dual communication type I/O modules (model suffix code "W").
Each I/O module is equipped with two independent communication ports, which are connected to the separate network modules.
Input modules continuously respond to request-to-send from the both lines. This secures two independent communications.
■ HOT INSERTION/REMOVAL OF I/O MODULES
Each I/O and network module has an independent CPU. Data is renewed by serial communications between modules. Therefore no momentary lapse or bumping of analog output occurs when switching communication buses in the dual communication mode.
Furthermore, removing or replacing modules does not affect other modules on the same backplane. It is possible to replace them without removing the power supply. However, replacing multiple modules at once may greatly change line voltage levels. We recommend that you replace them one by one.
PROFIBUS Standard requires that all outputs be turned off when turning the power supply on. Therefore remove the power before replacing the PROFIBUS modules.
