D2 - Overview of Registers 8DO eco and 8DO-R 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.
R121 Value Hex Controlling the DOs via bus command
DO No. (DO8 .. DO1) Each DO is assigned to a bit of the register:
1 00 01 Activating DO 1
… … …
8 00 80 Activating DO 8
R111
Value Hex Current state of the DO
DO No. (DO8 .. DO1) This register shows the current status of each DO. Each DO is
assigned to a bit of the register. The assignment corresponds to
that of the register R121 (Controlling the DOs via bus command)
1 00 01 State of DO 1
… … …
8 00 80 State of DO 8
R2135 Value Hex Setting the mask for 'Safe State' of the DOs
DO No. (DO8 .. DO1) If it is required that the DOs will have a defined state when the
bus fails, the corresponding bits of this register must be set to 1.
Each DO is assigned to a bit of the register. The assignment
corresponds to that of the register R121 (Controlling the DOs via
bus command). The settings of this register are stored in non-
volatile memory.
00 00 All DOs will retain their last state before bus failure
1 00 01 Setting in R 2121 determines DO 1 when Safe State is triggered
… … …
8 00 80 Setting in R 2121 determines DO 8 when Safe State is triggered
R2121 Value Hex Defining the DO's states for the 'Safe State' mode
DO No. (DO8 .. DO1) In this register, the states are defined which shall apply for the
outputs in case of a failure of the MODBus. The prior condition
is that the corresponding bits in register R 2135 are set to 1.
Each digital output is assigned to a bit of the register. The
assignment corresponds to that of the register R121 (Controlling
the DOs via bus command). The settings of this register are
stored in non-volatile memory.
00 00 All DOs will be switched OFF if safe state is triggered
1 00 01 DO 1 will be switched ON when safe state is triggered
… … …
8 00 80 DO 8 will be switched ON when safe state is triggered
