Code below is working, I'm sure you will rework it in a much better form.
Took a while to figure out to get AdsDataType "CHAR" 0x1E (30) instead of
"STRING" 0x20 (32).
```java
protected Optional<AdsDataTypeTableEntry> getDataTypeTableEntry(String
name) {
if(dataTypeTable.containsKey(name)) {
return Optional.of(dataTypeTable.get(name));
}
try {
AdsDataType adsDataType;
int numBytes;
if (name.startsWith("STRING(")) {
adsDataType = AdsDataType.valueOf("CHAR");
java.util.regex.Pattern pattern =
java.util.regex.Pattern.compile("\\((\\d+)\\)");
java.util.regex.Matcher matcher = pattern.matcher(name);
if (matcher.find()) {
numBytes = Integer.parseInt(matcher.group(1)) + 1;
}
else {
return Optional.empty();
}
}
else {
adsDataType = AdsDataType.valueOf(name);
numBytes = adsDataType.getNumBytes();
}
// !It seems that the dataType value differs from system to
system,
// !However, we never really seem to use that value, so I would
say it doesn't matter.
return Optional.of(new AdsDataTypeTableEntry(
128, 1, 0, 0, numBytes, 0,
adsDataType.getValue(), 0, 0, 0,
name, "", "",
Collections.emptyList(), Collections.emptyList(), new
byte[0]));
} catch (IllegalArgumentException e) {
return Optional.empty();
}
}
```
After all, « ARRAY [1..13] OF WORD » is returned by the plc.
Will continue testing other basic type I am using. And validate if writing
works.
