CONTROLLER ATTRIBUTE LISTING - COIL DATA
The tables in this section provide a listing of the 2050R boolean (discrete)
attributes which are addressed as coils. The description column identifies
the TRUE state of each attribute. The binary values are:
• TRUE = 1
• FALSE = 0
The tables list the attributes in order by Modbus coil number. The letters
below each number indicate whether the attribute is readable and writeable,
read only or write only:
• R W Readable and Writeable
• R _ Read only
• _ W Write only ( Write only applies to command type
attributes. They can be read but the
value returned is always 0.)
