7 Interface
Modules Format Meaning
status byte 16 bit flags for instrument status
actual
position signed long 32 bit current actual position in target-value increments
command
byte 16 bit flags for controlling the instrument
target
position signed long 32 bit next position to be achieved in target value
increments
parameters 8 bit index
signed int 16 bit data in
signed int 16 bit data out
set and/or read out parameters, indexed
actual
index 8 bit index of the parameter that has been read out
The status byte provides the user with information on the current status of the PSx3xxDP.
The actual position indicates the current position at which the positioning unit is located.
The command byte is used to transmit commands to the positioning unit.
The target position is used for transmitting the next position to be reached.
During operation, the parameter module allows users to adjust instrument settings directly (via
the control unit) that could otherwise only be modified when setting parameters.
