R2135
Value Hex Setting the mask for 'Safe State' of the DOs
DO No. (DO4 .. 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 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
… … …
4 00 08 Setting in R 2121 determines DO 4 when Safe State is triggered
R2121 Value Hex Defining the DO's states for the 'Safe State' mode
DO No. (DO4 .. 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 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
… … …
4 00 08 DO 4 will be switched ON when safe state is triggered

Value Hex Status of Digital Inputs
DI No. (DI4
… DI1) The bits of this register indicate the current status of the digital
inputs. The least significant bit is associated with DI1, followed
by the other ones up to DI4.
1 00 01 DI 1
2 00 02 DI 2
3 00 04 DI 3

Value Hex Inverting Digital Inputs
DI No. (DI4
… DI1) Using this register, the 4 digital inputs can be inverted
individually. Each DI is assigned to a bit of the register. The
assignment corresponds to that of the register R101 (current
status of the digital inputs). The settings of this register are
stored in non-volatile memory.
00 00 No DI is inverted
1 00 01 Inverting DI 1
2 00 02 Inverting DI 2
3 00 04 Inverting DI 3
4 00 08 Inverting DI 4
