Technical data

Once you have selected all the parameters in the first screen form for
your application, you can display the second screen form (Fig. 7-3)
with the following group of parameters:
ADDRESS. ERROR, CYCLE ERROR
ACKNOWL. ERROR, TIMER ERR.
COMMAND CODE ERROR, CONTROLLER ERROR
RUNTIME ERROR
PROCESS INT SERVICING
INTERRUPTABILITY OF USER PROGRAM BY
INTERRUPTS
The following flowchart explains how to complete the screen forms,
store the parameters and load the generated data block DX 0.
DX 0 - PARAM. ASS. (S5 135U: CPU 928, R PROCESSOR)
SYSTEM STOP IF EVENT OCCURS AND ERROR OB IS MISSING
PROCESS INT. SERVICING
INTERRUPTABILITY OF USER PROGRAM BY INTERRUPTS:
1: ALL INTERRUPTS AT BLOCK BOUNDS
2: ALL INTERRUPTS AT OPERATION BOUNDS
3: ONLY PROCESS INTERRUPTS AT OPERATION BOUNDS
4: ONLY PROC: AND CONTROLLER. INT. AT OP. BOUNDS
X: (X=10 , . . . 17) TIME INT. FROM OB10 - OBX AND CONTROLLER/PROC
INTS. AT OP. BOUNDS #ONLY POSSIBLE WITH CPU 928#
