Software Description
4.1
General
The device is freely programmable like a PLC.
The following sections explain the software features of the unit. They are of interest mainly
to those users who intend to write their own software.
Many rules and regulations for safety applications have been observed during all the
design stages (see section "Safety Concept").
The 1/209 device can be programmed using a handheld terminal pr439, any other
RS232C Terminal (e.g. VT100) or a personal computer. A MENU supported software
package is available for PC users (see PC-MENU-Disk).
Programming or reconfiguring is not required for standard applications.
In the normal way trip settings are accomplished via front panel push buttons. Additional
options are explained in the following chapters. A personal computer will allow for
maximum user friendlyness since all device functions are MENU supported via context
sensitive HELPs.
