3.2 Universal Inputs MODBUS Registers
Status of Universal Inputs working as Digital Inputs (30017)
This 16-bits register contains information about the status of Digital Inputs (dry contact).
When the input is shortcut to the ground the corresponding bit value is set to 1 in
accordance with the following table:
Table 13 UI register working as DI for MIX38 and MIX38-IP
Universal Input measure voltage (current) 1 - 8 (30071, 30073, 30075,
30077, 30079, 30087, 30089, 30091)
In these 16-bits registers are the results of measuring the voltage for each input. The result
is expressed in millivolts.
Measuring the current for each input results are stored in the same registers. In that case
the current value has to be calculated according to the equation:
[mA]
Universal Input measure temperature 1 - 8 (30072, 30074, 30076,
30078, 30080, 30095, 30097, 30099)
n these 16-bit registers. . The result is expressed in Celsius degrees • 10
Universal Input measure resistance 1 - 8 (30103, 30104 – 30117,
30118)
n these 32-bit registers. . The result is expressed in Ω or in 0,1 Ω for PT1000 and NI1000
configuration. In the register with lower number it is storage lower part of result and higher
register storage higher part of result.
Universal Input configuration 1 - 8 (40151 – 40158)
These 16-bit registers are used to configure Universal Inputs in accordance with the
following table:
