10.3 Bit parameters of the pico-PLC
Par. Description Def. Type/
Notes
Pb90.X Status of digital input X. If X is greater than
3, this is a bit that can be stored by the user
(b90.0 = converter enabled).
R/W
M
Pb91.Y Status of digital output Y. If Y is greater
than 1 this is a bit that can be stored by the
user. Parameter Pb91 is not saved and is set
to 0 when the unit is powered on.
R/W
Pb94.0 Force a double word formatted operation.
When the unit is powered on, this is 0. If it is
set to 1, the first mathematical operation
executed by the pico-PLC is done by using
three double word type operands. After the
execution of the operation b94.0 is
automatically set to 0.
If Pr58..Pr68 Pr110...Pr148 are used, the
double word formatting is implicit.
R/W
Pb94.5 First fast input disabl (94.5=1). When the
unit is powered on, this is 0.
R/W
M
Pb94.6 Second fast input disable (94.6=1). When
the unit is powered on, this is 0.
R/W
M
Pb99.0 Status of the first timer Equal to 1 if Pr92 =
0.
1 R/W
Pb99.1 Status of the second timer Equal to 1 if
Pr93 = 0.
1 R/W
Pb99.2 Equal to 1 if the result of the last PLC
operation is negative.
R/W
Pb99.3 Equal to 1 if the result of the last PLC
operation is 0.
R/W
Pb99.13 PLC status. Default=1. If set to 1, the PLC
program is executed, If 0, the program is not
executed, but the PLC instructions can be
modified.
1 R/W
