  • Page 28: Registers In Detail

    AIM Binary Tree 5.1.1 Registers in detail Registers 1-10 - Voltage Inputs These registers contain the measured input voltage in mV. The values are a signed 16 bit integer (2’s complement). All channels measure bipolar voltage with a nominal range of -10V... +10V. This means that the accuracy specifications is guaranteed for this range.
  • Page 29 AIM Binary Tree Registers 81-84 - Frequency inputs, pulse count These give values for the four frequency input pulse counts. Counts are incrementing and will wrap around to zero when the maximum value of the 16-bit counter (65535) has been reached. It is up to the application to take care of the rollover.
  • Page 30 AIM Binary Tree Registers 89-92 - Frequency inputs, pulse width ratio These give the measured pulse width ratio in tenths of a percent (0.1%) for the four frequency inputs. Method: Ratio = 100.0% * (input high count) / (input high count + input low count) Example: if a register has a value of 491, the pulse width ratio is 49.1% When the module detects that the input state of a channel has not changed for a while, the pulse width ratio value will be zeroed for that channel.
  • Page 31 AIM Binary Tree Register 201 - SW type The firmware type for AIM2505A module is 7. This is intended for EKE internal use. The range is 1..127 (bits 6.. 0). Bit 7 is the Release type bit. When zero, the firmware is a Base release that has been through formal acceptance test according to the test plan.
