Chapter 1 Redundancy System Overview
Figure 12 - Duplex and Simplex Connections
The example in
shows six connections; one for each entry in the
configuration.
The digital module connections use change-of state-triggers, and the adapter
and analog module connections use cyclic triggers.
RPI
The RPI you set specifies the maximum amount of time between data updates.
The 1715 modules support an RPI range of 60…750 ms.
Connection and Data Format
The adapter and I/O modules each support one data connection for input/
output data. Listen Only connections are not supported.
