Technical data

Example B:
Assigning the parameters to DX 0 as shown below achieves the following:
- the addressing error monitoring is disabled,
- the timer updating is disabled,
- the cycle time is set to 4 sec.
DX 0 start ID "MASKX0 DW 0: KH = 4D41
DW 1: KH = 534B
DW 2: KH = 5830
1st field ID/length DW 3: KH = 0203
parameter DW 4: KH = 3001
parameter
1)
DW 5: KH = BB00
DW 6: KH = 0000
2nd field ID/length DW 7: KH = 0402
parameter
1)
DW 8: KH = 1000
DW 9: KF = +4000
end delimiter DW10: KH = EEEE
This assignment of parameters to DX 0 has the following effects on
program execution:
- The part of the process image not assigned to peripheral I/O modules
can be used as an additional flag area.
- The runtime of the system program is reduced, since no timers are
updated.
- A cycle error is only detected when the runtime of the user program
and the system program together exceeds 4 sec.
1) Parameters occupying two words must be identified with "2" when
specifying the field length.
