Reference Guide for Setting Parameters in DB1

The following table gives you an overview of possible DB1 parameters. You require this table if you
wish to evaluate the parameters entered on the programmer without using COM 95F.
Parameter Argument
Block ID: OBHI
Default setting
HI 59.0 J
HI 59.1 J
HI 59.2 J
HI 59.3 J
Permissible changes
HI 59.0 N
HI 59.1 N
HI 59.2 N
HI 59.3 N
Block ID: OBP
Default setting
EB Y 0
AB 32 0
Permissible changes
EB y s
AB 32 s
EWA 4NEB 812 6210-02
Onboard hardware interrupt
The four onboard interrupt inputs I 59.0 to 59.3 are enabled for
OB2 interrupt processing.
Each onboard input of IB 59 can be disabled for OB2 interrupt
processing.
Therefore change the argument "J" (yes) from the default
setting to "N" (no).
Note:
Inputs of IB 59 that you disable for OB2 interrupt processing
can be used for OB3 interrupt processing (see parameter
block OBSI:). Inputs that you use neither for OB2 nor for OB3
interrupt processing can be used as failsafe DIs with short
discrepancy time.
On-board I/Os
All redundantly operated onboard inputs (IB 32, 33 and 59) are
assigned to signal group 0.
All redundantly operated onboard outputs (QB 32) are assigned
to signal group 0.
You can assign different signal group(s) to each input or output
byte:
permissible range of values
byte no. y:
y = 32, 33, 59, Y (Y: all)
signal group s:
s = 0, 1, ... 31
Note:
For input and output bytes that are not changed, the default
setting remains valid.
