Settings in TwinCAT PLC
Some of the settings for the BC2000 are only possible in PLC Control.
These are primarily a matter of properties that have a direct effect on the
program.
The points that follow here are found in PLC Control under „ONLINE“
„Coupler“.
Terminal Bus Reset
The terminal bus reset has its effect on the coupler’s internal bus. If there is
an error, which can be seen by the flashing of the „I/O ERR“ LED, the
terminal bus can be re-started. At the same time the number of connected
terminals is shown to the user in a message box.
Coupler Reset
The coupler will go through the same initialisation sequence as occurs
when the coupler is switched on.
Manufacturer’s Configuration
The coupler’s default values are written into the tables, and any boot project
that may be present is de-activated. The manufacturer’s configuration is
only activated after the coupler is reset.
Cycle Time Measurement
This measurement is related to the running time needed for the program to
execute and the terminal bus update. (See the chapter on „PLC Cycle
Time“)
Boot Project
In order to save the program, „Create a boot project“ is found under the
„Online“ menu item. This permits the program to be started automatically
after switching on. If the boot project is saved in the bus terminal controller
the „PLC“ LED on the BC2000 flashes.
