6.9 Signal Tag Register Map
Summary
Signal tags are connected to output pins of function blocks, representing analog or digital parameters, and
are read-only parameters. Digital Signal tags are also represented in floating point, 0.0 for OFF or logic 0,
1.0 for ON or logic 1. The signal tag number in the table corresponds to the signal tag number in the
HC900 Hybrid Control Designer configuration. You will need to access the Hybrid Control Designer
configuration "Tag Information" report to identify the Signal Tag numbers desired.
Note: to convert floating point values (analog or digital) to integer 16, for use with third party touch panels
and associated HMI software, for example, requires the use of the user-defined modbus map for assigning
new modbus addresses and associated data type, configurable in HC Designer, Ver. 2.0 or later.
Function Code Support:
Read – Function Code 3
NOTES:
Floating Point in Engineering Units
Digital Signal Tags are represented as 0.0 for OFF, 1.0 for ON.
Access is Read Only
