System configuration with PN/J1939 LINK
Purpose and function of the system components
PN/J1939 LINK enables PROFINET to be connected to a J1939 network.
Communication of the PN/J1939 LINK with the CPU of the S7 controller takes place
exclusively via the PROFINET interface.
From a PROFINET perspective, the PN/J1939 LINK is an IO device according to
Conformance Class B (CC-B).
From a J1939 perspective, the PN/J1939 LINK is an Electronic Control Unit (ECU) and
contains a Controller Application (CA).
The cyclic data exchange between the PN/J1939 LINK and the connected S7 CPU takes
place via an update of the IO image. Acyclic communication takes place by means of the
"Read data record" and "Write data record" services.
PN/J1939 LINK is powered either via an external 24 V DC power supply unit or via the
24 V power supply of the SIMATIC S7 system.
The TIA Portal is used for configuring. A corresponding GSDML file is available for this
purpose.
