NETWORK REDUNDANT SYSTEM

The dual network system is only available using two (2) interface modules (with option /W). In case that a single interface module is mounted, RUN and ERR indicator LED turn off. Before turn on the power, be sure to mount two interface modules.
The modules must be mounted on a 36.5 mm width base (model: R6x-BS8B). Please, be sure to set always one of the two (2) interface modules’ SW8 as main, and the other one as sub. If the both modules are set as main or both as sub, none of them is operable. When the main network module is in main-operation mode, the sub network module is in sub-operation mode.
The main-operating module is able to transmit input data and to set output data. The sub-operating module is able to input data. However, since the main-operating module has the priority, the sub-operating module is not able to set output data.
In case of communication error, failure or detachment in the main network module, the sub network module takes over the main-operation. When the failed main network module is replaced or its transmission is recovered, its operation mode is selectable with DIP SW.

TRANSMISSION DATA DESCRIPTIONS

The DIP SW located at the side of the module switches the unit’s data allocation mode.
In the Data Allocation Mode 1, one (1) word is assigned per module. The second channel of analog I/O modules cannot be used.
In the Data Allocation Mode 2, two (2) words are assigned per module regardless of whether the second word area is required or not, even for discrete I/O modules that require one (1) word.
A maximum of 32 I/O modules can be mounted per node.
Each Status data is available when the Ready is “1” (the internal bus in normal condition). While the Ready is “0,” all of the Status data is “0” (the internal bus in abnormal condition).
