Support Questions / Logix & ReadUDT latest AHMI -V3.99y
« on: June 29, 2018, 01:38:39 AM »
Hi all, as always great work Archie (legend),
Good chance this is a noob issue (bit rusty) apologies in advance. PLC has UDT tag DateTime02 structure/WallClock (all good)
I have the below - WriteUDT (writes no probs.) / ReadUDT I get the following error
'System.IndexOutOfRangeException' on the ReadUDT line. Any help would be appreciated.
Cheers
