Par. Description Field Range Def. Res.
Pr88
Free parameter. A parameter that can be stored
by the user (word).
R/W -32768÷+32767 0 1
Par. Description Field Def.
b90.0
Digital input 0.
R 0
b90.1
Digital input 1.
R 0
b90.2
Digital input 2.
R 0
b90.3
Digital input 3.
R 0
b90.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).
W 0
b91.0
Digital output 0.
W
b91.1
Digital output 1.
W
b91.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.
W 0
Pr92
First timer of the PLC. Every 6.144 ms, if Pr92 is not 0, it is decremented.
If it is equal to 0, b99.0 is set to 1.
W 0
Pr93
Second time of the PLC. Every 6.144 ms, if Pr93 is not 0, it is
decremented. If it is equal to 0, b99.1 is set to 1.
W 0
b94.0
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 Pr60..Pr68
Pr110...Pr148 are used, the double word formatting is implicit.
W 0
b94.5
First fast input disable (b94.5=1). When the unit is powered on, this is 0.
W 0
b94.6
Second fast input disable (b94.6=1). When the unit is powered on, this is
0.
W 0
b99.0
Status of the first timer. Equal to 1 if Pr92 = 0.
W 0
b99.1
Status of the second timer. Equal to 1 if Pr93 = 0.
W 0
b99.2
Equal to 1 if the result of the last PLC operation is negative.
W 0
b99.3
Equal to 1 if the result of the last PLC operation is 0.
W 0
b99.13
PLC status. If set to 1, the PLC program is executed. If 0, the program is
not executed, but the PLC instructions can be modified.
W 1
