Commissioning
EL125x, EL2258 119 Version: 2.5
• “Multi-timestamp PDOs” and “compatible PDOs” cannot be combined
• The corresponding control/status must be active for each active input/output channel
• The MTSF can be set freely from 1 to 10 for each channel
• Only 1 multi-timestamp factor may be active per channel. It is therefore not permitted to activate PDO
"MTO Outputs 5x Channel 1" and PDO "MTO Outputs 2x Channel 1" at the same time, for example.
If an irregular PDO combination is selected, it may lead to the ERR-PREOP state ‘invalid output mapping’ or
‘invalid input mapping’.

The section below describes commissioning of a digital input terminal with multi-timestamp function at a
PLC.
6.5.1 Basic principles
Each MTI channel (multi-timestamp input) has inputs and outputs in the cyclic process image, which have to
be linked with the PLC/task.
