Logic Processor User's Manual
•
COM600F is a dedicated distribution automation controller unit that runs dis-
tributed grid and feeder applications for ANSI power networks and inherits all
core features of the COM600 series.

Functional overview

The Logic Processor function enables developing customer-specific automated applica-
tions for COM600. Applications are programmed using the IEC 61131-3 logic editor
(CoDeSys). The COM600 unit has the logic engine (CoDeSys Control Win V3 Runtime),
which can load and execute the created IEC 61131-3 applications. Information transfer
between the logic engine and other COM600 components, such as OPC Servers, slave
clients and WebHMI, is handled by the Logic Processor OPC Server. It enables the logic
variables to be connected to the process signals available via different communication
protocols in COM600.
The shortest possible data transfer cycle between process signals and logic variables is
50 ms.
The logic program might not detect progress data changes that
are faster than or close to the transfer cycle time.
The default task interval of the logic program is 200 ms. The theoretical response time
of the logic program to process signal change with a process control command is 300
ms (=50 ms + 200 ms + 50 ms). The task inteval of the logic program can be set from
the Task Configuration dialog (see 3.3.3, Add POU to Application MainTask).
For information about the actual logic programming, see CoDeSys documentation.
