D6 - Overview of Registers 8AO eco Module
In the following descriptions of the register settings,
default values , if any, are highlighted . These settings
are suitable for most applications and at the initial commissioning.
The values in the underlined registers are stored in non-volatile memory. These registers should not be
written continuously.
(
*
)
The registers marked with this asterisk can be read or written only individually, not as a
contiguous block.
R521 Register Controlling the AOs via bus command
…
Each register contains the control value of an analog output
(values 0 ... 1000 correspond to 0 ... 10V)
R528 R 521 Control value for AO 1
… …
R 528 Control value for AO 8
R511
Register Actual values of the AO
…
Each register contains the actual value of an analog output
R518 R 511 Actual value of AO 1
… …
R 518 Actual value of AO 8
R2535
Value Hex Setting the mask for 'Safe State' of the AOs
AO No. (AO8 .. AO1) If it is required that the AOs will have a defined value when the
bus fails, the corresponding bits of this register must be set to 1.
Each AO is assigned to a bit of the register. The settings of this
register are stored in non-volatile memory.
00 00 All AOs will retain their last value before bus failure
1 00 01 Value in R 2521 will determine AO 1 when safe state is triggered
… … …
8 00 80 Value in R 2528 will determine AO 8 when safe state is triggered
R2521 Register Defining the AO's values for the 'Safe State' mode
…
When the MODBus fails, the outputs will assume the values that
are set in these registers. Prior condition for this mode of
operation is that the corresponding bits in the register R2535 are
set to 1. Each register contains the control value of one AO. The
settings of this registers are stored in non-volatile memory.
