8.5.3 Loop Setup Menu
This page displays and controls options affecting the current loop.
The 'Doubling Enable' allows loop speed doubling to be enabled (ON) or disabled (OFF). If enabled, the
master station automatically doubles the loop baud rate if it finds that the loop is complete. This improves the
scan time. In a few cases it may be necessary to disable this feature if it causes a high error rate on the loop.
Commands available:
- Step round the loop baud rate options. Choices are 110, 300, 600, 1200, and
- Change the highest field unit address on the loop. The master station polls all
field units up to this highest address. The scan time is minimised if polling is
restricted to only those field units which may be present.
- Toggle between doubling enabled and disabled.
- Return to previous menu
