For configuring I/O scanning, the read and write zones are general at the remote inputs/outputs:
This sub-window is used to define the ranges of internal words of the application memory (%MW) specific to the read and write zones.
To do this, you must complete:
-
for the read zone, Read Ref. (the starting address in the table of internal words for reading inputs)
-
for the write zone Write Ref. (the starting address in the table of internal words for writing outputs)
The length of tables has a maximum exchange capacity of:
-
2 Kwords for the read zone (ETY 4103/ETY 5103/ETY PORT)
-
4 Kwords for the read zone (TSX P57 6634/5634/4634)
-
2 Kwords for the write zone (ETY 4103/ETY5103/ETY PORT)
-
4 Kwords for the write zone (TSX P57 6634/5634/4634)
NOTE: The tables must not overlap and an overrun check is made on global validation.
