Note
Reading of DR30 to the PLC via command is not mandatory. In DR07 Interface parameters
(Page 72), the user can freely select four process variables that are transmitted automatically
via the S7-I/O to the CPU and are available there. In addition, the complete scale status is
always available cyclically in the I/O (see section TIA Portal user program (Page 38)) and can
thus be used directly in the PLC program. At the Modbus end, the parameters and status
information from DR30 are always current and the registers can therefore be read immediately.
6.23.2 Digits unfiltered (linearized) [unfilteredDigitsNotLin]
The unfiltered digit value is the internal measured value before filtering.
6.23.3 Digits filtered by F1 [filteredDigits1]
The filtered digit value is the internal measured value after filtering with filters defined in DR 3.
6.23.4 Digits filtered by F2 [filteredDigits2]
The filtered digit value is the internal measured value after filtering with the average value low
pass filter and dosing filter from DR03.
6.23.5 Digits filtered by F3 [filteredDigits3]
The filtered digit value is the internal measured value after filtering with the average value and
low pass filter from DR03.
6.23.6 Status DI.0, DI.1, DI.2 and CI.0 [statusDI0] [statusDI1] [statusDI2] [statusCI0]
Current status of digital inputs DI.0 to DI.2 and CI.0.
6.23.7 Status DQ.0, DQ.1 and DQ.2 [statusDQ0 to statusDQ2]
Current status of digital outputs DQ.0 to DQ.3.
