Operating Instructions
2.7 General Interrupt Processing with S5–150 S/U
The operating system of the programmable controller scans the peripheral byte O
(PYO)
at each
block limit.
When an interrupt occurs, a jump to the correlated interrupt organization block
(OB2
to
OB9)
takes place.
In the programmable controller the bits 0.0 to 0.7 are directly allocated to the
OBS
2 to
OB9.
Bit 0.0 activates OB2, bit 0.1 activates
OB3
and so
on.
A bit of byte O can be allocated to any
1P
241.
This allows a maximum of 8
IPs
with interrupt processing in the expansion unit.
In the programmable controller S5–150SIU, the
1P
241 may only be operated in the
Example:
x = closed
– = open
