Universal Input Registers

Status of Universal Inputs Working as Digital Inputs (30017)

This 16-bit register contains information about the status of digital inputs (dry contacts). If the input is shorted to the ground, the corresponding bit value is set to 1 in accordance with the following table:

UI register operating DI for MIX38 and MIX38-IP

Universal Input Voltage (Current) Measure 1-8 (30071, 30073, 30075, 30077, 30079, 30081, 30083, 30085)

These 16-bit registers contain the results of measuring the voltage for each input. The result is expressed in millivolts.

The results of measuring the current for each input are stored in the same registers. In such case, the current value has to be calculated according to the equation:

I = register value / 200 [mA]

Universal Input Temperature Measurement 1-8 (30072, 30074, 30076, 30078, 30080, 30082, 30084, 30086)

In these 16-bit registers the result is expressed in Celsius degrees • 10.

Universal Input Resistance Measurement 1-8 (30103-30118)

In these 16-bit registers the result is expressed in Ω or in 0.1 Ω units for PT1000 and NI1000 configuration. In the register with the lower number, it is the lower storage part of the result and the higher register storage part of the result.

Universal Input Configuration 1-8 (40151-40158)

These 16-bit registers are used to configure universal inputs in accordance with the following table:

UI configuration

Filter Time Constant of the Universal Input 1-8 (40159-40166)

These 16-bit registers contain a time constant low pass filter. The value is expressed in seconds. Valid values must be between 0 and 60 seconds. The default filter value is 2 seconds. Setting the value to 0 disables the filter.

In case of the UI shortcut or open-loop, the filter is reset and the UI value filtering is stopped.

Resolution of the Universal Inputs (40167)

This register is used to determine the bit resolution for each of the universal inputs.

Setting the bit to 0 sets the resolution of the converter to 12-bit. Setting the bit to 1 sets the resolution of the converter to 16-bit.

WARNING!

Setting 16-bit resolution increases the measurement time of one channel from 10 ms to 140 ms. The total time taken to measure all the channels increases from 50 ms to 700 ms.

Each input can be configured separately in accordance with the following table:
