36 • DDE Item Names In PCIS-DDE
* To get the value of Nth bit of PDO0/PDO1 by using Tag.0N as the item
name, the data type of PDO0/PDO1 have to be set as integer. As
mentioned before, the “integer” is “32-bit signed integer” in InTouch. That
means the range of “integer” is –2147483648 ~ 2147483647. However, to
poke 32-bit unsigned data, use “PSDO0” or “PSDO1” (the data type is
string) for digital output.
