Page 9 – Total Harmonic Distortion
Notes:
1. These are read only registers.
2. Only supported on 88xx/84xx modules at present (introduced at version 1.0 of these modules)
3. 8810/8410 don’t support registers 120-131 – they will return Unimplemented (sentinel value)

Notes:
4. These are read only registers.
5. Register 0 gives the version as major/minor, with the major version in the upper 8 bits, the minor version in the lower 8 bits.

Page 12 - Diagnostic - Digital Inputs
Notes
1. These are read only registers.
2. These registers represent the state of the actual inputs to the control unit before the application of any time delays or other processing and are intended for diagnostic purposes only.
3. The number of named digital inputs may be increased in future versions of GenComm. Manufacturers may not add their own to the list of named inputs as there are no corresponding strings to identify them. Any inputs that are required but not named must be included in the list of unnamed digital inputs.
4. The meaning of the named digital input codes is shown in the table below.
5. Register 16 indicates the number of unnamed digital inputs that are supported, any software that displays these must cope with any number up to 128. Each is represented by only one bit as there is no need to indicate that it is unimplemented.
6. Unimplemented inputs (including totally unimplemented registers) return 3, not an exception.
