SERCOS (Optional)
The optical SERCOS fibers must be connected to the optional connectors
X7S1 (receiver) and X7S2 (transmitter). Since a SERCOS bus is of
circular setup, the optical fiber cables must be properly connected to
these two connectors. The SERCOS interface can be operated with 2, 3,
8, or 16 Mbauds. The transmission rate as well as the transmitter output
can be set by means of the firmware.
A red "Dist." light-emitting diode is assigned to the SERCOS interface.
"Dist." LED Meaning
Off Normal state
Red The distortion is too high or the receive signal is missing.

Ready Contact (Optional)
Pins 1 and 2 of the 3-pin strip X2R are the connection points for the
optional Ready contact.
The Ready contact has a single-channel setup.
Characteristic relay data (photo-MOS
relay)
Switching capacity 1 A, 60 V DC
Dropout time 0.3 ms
Bounce time None
Watchdog time (analog WD only)
50 ms ± 25 %
Fig. 7-25: Characteristic data of Ready contact
If it is in the release state, the Ready contact is open. After powering up of
the assembly, the contact is closed. The contact is opened again, if one of
the states listed below occurs:
• The 24-VDC supply voltage falls below the permissible limit.
• The internal 5-V and 3.3-V voltages fall below the permissible limit.
• The Ready watchdog is elapsing.
• The Reset button is actuated.
