Scheduling and the LAS

The 1788-CN2FFR/1788-EN2FFR linking device generates the LAS schedule,

which determines when each function block executes and transmits data. Newly

added field devices are automatically added to the schedule, and removed from

the schedule when removed from the live list.

Figure 7 - Master Configuration Dialog Box

The Download Schedule function is only needed when the 1788-CN2FFR/

1788-EN2FFR linking device has been replaced.

Redundant Master Setup

You can configure a second 1788-CN2FFR/1788-EN2FFR linking device to act

as a backup. You can choose from various architectures (see Appendix D

). The

figure shows an example of MultiMaster architecture, A bus only, with a shared

termination.

IMPORTANT

When connecting to running linking devices, you must follow the procedures

in MultiMaster Connecting Procedures

on page 46 to avoid losing the

connection to certain devices.

IMPORTANT

You must not have any other back-up LAS devices. Be sure that the field devices

have been configured with the class set to basic. See Field Device Class

page 42.

IMPORTANT

Test and verify that the specific field devices that are connected to the

MultiMaster operate correctly when one of the linking devices fails.
