CONTROLLER ATTRIBUTE LISTING - REGISTER DATA
CONTROLLER ATTRIBUTE LISTING - REGISTER DATA
The tables in this section provide a listing of the controller’s numeric attributes
which are addressed as registers. The tables divide the attributes into related
groups such as tuning, alarms, etc. A group of numeric attributes may have
associated boolean (discrete) attributes which are addressed as coils. The
boolean attributes are listed in the next section.
The following tables list the attributes in order by Modbus register number.
The letters below each number indicate whether the attribute is readable and
writeable or read only:
• R W Readable and Writeable
• R _ Read only
