Dynamix Relay; Module Object - Allen-Bradley 1444-TSCX02-02RB User Manual

Dynamix Relay 

Module Object

For multiplexed measurements it is possible that the available Tacho Times do
not always provide full coverage for the sample data. This situation can occur
when low frequency / slow speed measurements, where fewer than 16 samples
per revolution and the full extent of the circular sample buffers is used. This
can lead to errors in the speed measurement.
Individual mode is also implemented, where each channel is allocated to its
own individual time slot. As individual mode provides little operational
advantage over paired mode, the latter is recommended for all multiplexing
applications.
The Relay Module Object (class code 0x39C) configures the relay outputs of
the associated relay expansion modules (1...3 units per host, each serving four
mechanical relays).
The object defines the setup for the Relay Output expansion modules and the
interaction of these expansion modules with the main module. The same host
module can accommodate up to three Relay Output modules. There is an
object instance per module.
When one or more Relay modules are included in a system, not only must the
configuration aspects of this object be addressed, but the presence of each
module must also be flagged by appropriate setting of the Module Control
Object, class attribute 16 (Configured Auxiliary Modules).
