I am using Intouch App Server 3.0 and a Siemens S7-300 PLC. I have a data block that contains a two dimensional array of characters (10 strings of 32 characters each). I can read/write the values for the first 6 strings (0-5) from Wonderware. However, the last 4 strings show as a bad value. The input source for the first bad value is DB75,S192,32. Is there a limit to the amount of data that can be read from a data block?
