Downloading the field bus parameters
– The parameters of the field bus module are always
loaded into the SPC200 within the complete project.
A system reset then takes place. A separate
download of the field bus parameters is not possible.
– The field bus module is ready for operation on the
INTERBUS when the LED “RD” lights up (the
initialization phase of the SPC200 is then concluded).
Control panel
Configuration of the process data channel can also be
carried out with the control panel of the SPC200. To do
this switch to the menu "CONFIG.SYSTEM" and select
