Equipments (Devices) > SSW900

The following variables contained in teh GLOBAL_SYSTEM group of the variables table, have the fixed tag. The tag of system markers were divided into groups and subgroups, wher:do:

Grupos:

•	SSW: reading and writing variables of the SSW900 soft-starter.

Subgroups:

•	STS: reading variable (status);

•	CMD: writing variable (command).
