2.3.14 Supply of external sensors via the terminals of type EL9185
The potential distribution terminal of type EL9185 allows to provide 4 power supply
connections. The supply voltage is provided by the power supply terminal EL9410. It transmits
the voltage Up via the power contacts to the potential distribution terminal. If the supply voltage
Up of the power contacts of the power supply terminal EL9410 is galvanic isolated from the
supply voltage Us of the control supply, the same applies to the voltage of the potential
distribution terminal. The potential distribution terminal serves as a provider of supply voltage
for external sensors. Normally the clamps labeled with black + on red ground and black - on
blue ground provide +24 V
DC
. The label of the terminal is in the range of PV01 and PV09.
Picture 7 shows the potential distribution terminal PV01 for supplying displacement sensors
with its supply voltage.
Note:
The EtherCAT terminal EL9185 is a passive terminal that does not take an active part
in the data exchange process of the terminal block. A current consumption form the E-Bus
does not take place. Thus it is a passive terminal.
It is not allowed to put two passive
terminals directly next to each. An optimal data exchange is not guaranteed in this case.
2.3.15 Connection of PROFIBUS to terminal of type EL6731-0010
The Peakanalyzer can optionally be equipped with a PROFIBUS slave terminal of type
EL6731-0010. This terminal provides the possibility of an integration in an existing PROFIBUS
system. Thus the Peakanalyzer can receive process factors and speed information.
Furthermore the Peakanalyzer can provide alarm information of process factors, characteristic
values or kinematic alarms. Information about warn and alarm threshold exceeding are also
send. The PROFIBUS slave terminal can operate in the following protocols: PROFIBUS DP
(Standard), PROFIBUS DP-V1, PROFIBUS DB-V2 as well as PROFIBUS MC. With this
terminal there are DP cycle times of 200 µs at a transmit rate of 12 MBaud possible. In the
hardware configuration there must be a power supply terminal of type EL9410 directly after the
PROFIBUS slave terminal on the right side or an end cap EL9011 (Picture 14).
The PROFIBUS is connected through the galvanic decoupled 9-pin D-Sub socket. It is
recommended to use the 9-pin D-Sub-PROFIBUS connector ZB3100 with switchable end
resistor. Thus the first and last participant in the bus can be operate with an active end resistor
as required. The end resistor can be activated by a switch in the connector.
The connection of the two wire cable is done with the red standard wire at pin 3 (RxD/TxD
–
P, A) and with the green standard wire at pin 8 (RxD/TxD
– N, B). These two contacts are for
the communication. An installation description for the mounting of the cable to the PROFIBUS
connector ZB3100 can be found in the supply material of the connector. It is recommended to
use a PROFIBUS cable of type ZB3200 with 2 x 0.64 mm² for a fixed installation. If the
installation has to be done in a drag chain, the PROFIBUS cable ZB3300 is recommended.
