Control bits Notes
C_DOPARAM Change function and behavior of DO1, DO2
The values from bytes 0 to 2 are applied as new function, hysteresis, and pulse duration of DO1,
DO2. This may result in the following error: The conditions for the "Switch at comparison values"
behavior are not fulfilled.
CMP_VAL1 Load comparison value 1
The value from bytes 0 to 3 is transferred to comparison value 1 with the control bit "Load
comparison value CMP_VAL1".
CMP_VAL2 Load comparison value 2
The value from bytes 0 to 3 is transferred to comparison value 2 with the control bit "Load
comparison value CMP_VAL2".
CTRL_DO1 Enable DO1
You use this bit to enable the DO1 output.
CTRL_DO2 Enable DO2
You use this bit to enable the DO2 output.
CTRL_SYN You use this bit to enable synchronization.
EXTF_ACK Error acknowledgment
The error bits must be acknowledged with the EXTF_ACK control bit after the cause is removed.
LOAD_PREPARE Load counter preparatory
The value from bytes 0 to 3 is applied as the load value.
LOAD_VAL The value from bytes 0 to 3 is loaded directly as the new count value.
