MSC-3 Start Up
Duplicate Selections
It is possible to select the same input terminal for several input functions. In some cases a single digital
input feeding several input functions may not be desirable. When an input terminal is selected for the
2nd (or 3rd, 4th,…) time, the MSC3 presents a warning message and question asking to remove all
existing uses for the selected terminal.
For example the default setup is
I07 RESET = D1(2)
I02 ~STOP = D2(3)
I00 FWD & LATCH = D3(4)
I11 REMOTE = D4(5)
The operator decides to have EXTERNAL WARNING activated by D4(5). That is:
I13 EXTERN WARN
> D4(5)
When the operator presses the ENTER push button to make the selection, the following sequence of
messages is displayed:
SELECTED
TERMINAL IN USE
REMOVE ALL
EXISTING USES?
ENTER=yes ESC=no
?
If the operator presses ENTER for "yes", the outcome will be:
I07 RESET = D1(2)
I02 ~STOP = D2(3)
I00 FWD & LATCH = D3(4)
I11 REMOTE = OFF
I13 EXTERN WARN = D4(5)
All previous selections
of D4(5) are set to OFF
If the operator presses ESC for "no", the outcome will be:
I07 RESET = D1(2)
I02 ~STOP = D2(3)
I00 FWD & LATCH = D3(4)
I11 REMOTE = D4(5)
I13 EXTERN WARN = D4(5)
Previous selectios of
D4(5) remain
