RMC75 Register Map - File 26 Analog Inputs

RMC75 Registers, File 26: Analog Inputs

The Analog Inputs register file holds the voltage or current of all the analog inputs on the controller. These Analog Input registers exist in order to display all the analog inputs, even those that are not assigned to axes, since the RMC75 can have more analog inputs than can be assigned to axes.

For analog inputs that are not assigned to axes, only the voltage is available. No status or error bits, filtering, scaling, input range selection, raw counts, halt groups, etc. are available. Current transducers can still be used by connecting the 4-20mA jumper, but the user will have make the conversion from voltage to current (1V = 4mA, 5V = 20mA, current in mA = (volts x 4)).

For analog inputs that are assigned to an axis, the value in the existing Current or Voltage axis status register will be copied into this file.

The analog inputs are ordered by slot (left-to-right), and top-to-bottom within each slot. The register values for inputs that do not exist will be zero.

Usage Notes

Viewing the Analog Voltage

To view the Analog Input values in RMCTools, enter the address of the input in the Map To column in the Indirect Data Map. The analog input value will appear in the Current column of the Indirect Data Map.

Uses

These registers can be used for plotting, can be used in expressions, and can be read by an external device such as a PLC. They can also be used as a gear Master Register, just like any other REAL register, but notice that no filtering or advanced rate calculations will be provided. Also, because the input cannot be part of a halt group, the safety of using the input for gearing must be evaluated by the integrator.

Tag Names

The analog inputs can be referenced with the tag names _AI[i], where i is the input number. For example analog input 3 is _AI[3].
