CAN bus connection interface
The PQF-Manager communicates with the main controller through a CAN bus. This bus
consists of three terminals, i.e.:
- Pin H: CAN High signal
- Pin L: CAN Low signal
- Pin Shield: shielding
The CAN bus wiring terminates into the PQF-Manager connection plug and is
subsequently routed to the main control (Cf.
communications only.
7
Power supply terminals
The PQF-Manager power supply is provided by the filter itself. The corresponding
terminals on the PQF-Manager labeled "Power supply" are connected to the PQF-
Manager connection plug.
8
The PQF-Manager communicates with Modbus TCP and PQ-link thanks to the
Ethernet connection. For background information on the Modbus RTU and TCP
communication interface refer to the dedicated Modbus manual. For background
information on the PQ-link communication interface refer to the dedicated PQ-link
manual.
9
The PQF-Manager can communicate with PQ-link (PC software) also through USB. .
For background information on the PQ-link communication interface refer to the
dedicated PQ-link manual.
10
External temperature probes can be added. The PQF-manager can handle until 8
temperature probes connected in a daisy chain way. Please refer to the Temperature
probe User's guide for more information.
For information on how to cable external systems (e.g. remote control, Modbus
interface) to the PQF-Manager, refer to
PQF-Manager, refer to
TCP communication interface refer to the dedicated Modbus
information on the PQ-link communication interface refer to the dedicated PQ-link
manual.
