Communication between sender/receiver units and control unit
Configuration
Description
1-path
measurement -
connection of one
measuring point
to the MCUP
Two sender/receiver units (type EX-S, EX und EX-RE) are
connected to the MCUP and work as master and slave.
The FLSE master has a second interface in the terminal box
to enable unique separation of the communication to the
FLSE slave and to the MCUP. The master triggers the slave
and takes over the measuring regime. The MCUP can
independently query the measured values from the master
units (asynchronous to the measuring cycle).
The master-slave communication of the device type EX-PR is realized internally in the single
sender/receiver unit. The sender/receiver unit is directly connected to the MCUP.
2-path and
2x1-path
measurement -
connection and
computation of
two measuring
paths of a
measuring point
to the MCUP
The master-slave communication is realized using the same principle as for the single path
measurement. The connection of both measuring paths is usually carried out with bus
cabling.
An approved explosion-protected junction box (SICK option) is to be used for cabling in Ex
zone 2. Cabling in hazardous areas Ex zone 1 may be carried out only with an approved
"Exe" junction box or "Ex-d" junction box (not included in SICK scope of delivery).
3x1-path
measurement -
connection of
three measuring
paths of different
measuring points
to the MCUP
The master-slave communication is realized using the same principle as for the single path
measurement. The connection of all measuring paths have to be carried out with bus
cabling.
An approved explosion-protected junction box (SICK option) is to be used for cabling in Ex
zone 2. Cabling in hazardous areas Ex zone 1 may be carried out only with an approved
"Exe" junction box or "Ex-d" junction box (not included in SICK scope of delivery).
