3.1. Status LED’s
5 LED’s will deliver information on the VME-PROF-S's operating state. The meaning of the
1. LED row is independent of the loaded firmware:
1. LED-row (VMEbus state)
green
(
A
active)
VMEbus access to the VME-PROF-S
yellow
(
S
)
reserved
red
(
F
Fail)
the VME-PROF-S is in RESET (disabled), only the
Monitor program is running. The VMEbus-SYSFAIL is
generated by the VME-PROF-S
2. LED-row (PROFIBUS state)
with PROFIBUS-DP-Slave firmware
green
(R RxData)
the VME-PROF-S receives data from the PROFIBUS
yellow
(T TxData)
the VME-PROF-S sending data to the PROFIBUS
red
(
C
Com-Fail) Off:
The VME-PROF-S is configurated by the DP-
Master and transfers data
On:
the VME-PROF-S is in hold or not/wrong
configurated by a DP-Master, no data transfer
3.2. Interfaces
3.2.1. PROFIBUS-Interface X2
The PROFIBUS an be accessed via a 9-pin connector X2 located at the front panel. The
interface has separated potentials and a pin-layout as specified in the DIN 19245.
