Only a Daisy-Chained Data Bus Topology is Acceptable
Use a daisy-chained Modbus RTU data bus topology only. No other data bus topology is
allowed.
Only linear, daisy-chained devices provide predictable data bus impedances
required for reliable data bus operation.
Only a daisy-chained data bus topology should be specified during the planning
stages of a project and implemented in the installation phase of the project.
