Value (Gray Type)
Under the address set with “Config. Index”, you can now enter the configuration
value. You will find this value and its significance in the chapter “Interface
Submodules” under the relevant interface submodule.
The configuration value positioned on the left is the setpoint. You can edit this
value. When you have entered it, confirm by pressing the Tab key or the key
combination Shift Tab , so that it is accepted. The configuration value shown
to the right of this in gray type (black type in Remote Setup) is the actual value
(determined at the last power up of the CPU). It cannot be edited. If there is no
submodule in the submodule receptacle, the value “FF” is displayed.
SIG Source
Here, you enter the signal source if the relevant interface submodule is designed
for it (“Interface Submodules” chapter). The values for the signal source positioned
on the left are the setpoints. You can edit these. The values shown to the right of
this in gray type (black type in Remote Setup) are the actual values (determined at
the last power up of the CPU).
SIG Dest.
Here you enter the signal destination if the relevant interface submodule is
designed for it (“Interface Submodules” chapter). This value is entered only once
per expansion module at the first submodule receptacle (0, 3, 6, 9, etc.). The value
for the signal destination positioned on the left is the setpoint. You can edit this
value. The signal destination value shown to the right of this in gray type (black
