Unknown data type DT

[joed74]

I cannot read DateTime (DT) fields in my CLX plc:

2023-09-15 16:27:27.822 thread(3) tag(0) INFO unpack_response:1651 00048 00 00 c0 00 63 94 90 97 66 05 06 00
2023-09-15 16:27:27.823 thread(2) tag(0) WARN check_read_status_connected:1448 Unsupported data type returned, type byte=192

The underlying datatype is just an ULint (or Lint)

I think it has to be added to defs.h

#define AB_CIP_DATA_DT ((uint8_t)0xC0) /* DT value, 64 bit */

Interestingly, the LDT data type (called STIME in libplctag, type 0xCC) works out of the box

Unfortunately, the types are not really used anywhere. Only atomic values seem to be directly supported.

But I can add this in for what it is worth.
