-==== Multiple groups ====
-  * When the system has two or more separate Modbus lines, they should be configured as separate groups.
-  * Each group has a single master and one or more slaves.
-  * Groups can't talk to each other, but they share the same bandwidth.
-  * Two masters may start transmitting at the same time causing collisions.
-  * To reduce number of missed messages, keep the traffic low.
