Depending on the axis definition, the characters for measured
value output are generated in the following order:

Storage via
External Functions
Contact closing against 0 V on the 25-pole D-subminiature
socket X41 causes a storage signal to be generated and the
measured value to be transmitted over the TXD output of the
RS-232-C interface. The time required for data transfer
depends on the selected baud rate, the number of axes. the
number of line feeds and the type of storage signal (pulse or
contact).

ment.
The transit time of the encoder signals from input to the internal
buffer is approximately 4 IJs. The measured value which is
stored is therefore the value which existed approximately 4 IJS
prior to the time point of storage.
