Note All Outputs are Read/Write (x=0 to 65,535, y=0 to 7, n=0 to 65,534, m=0 to

65,532, v=1 to net PDU data size/type size - header information, this size may vary).

The longest string or array that can be read in a cyclic service has the length of the PDU

size minus 32 bytes. The longest string InTouch can process is 131 bytes. The longest

string that can be poked is 256 bytes or the PDU size minus 28 bytes, whichever is less.

Arrays are converted into HEXASCII strings representing the big endian format of the

binary data. The Wonderware Siemens SIMATIC NET S7 I/O Server will process a

write (POKE) to an Output Byte.
