Note All Peripheral Inputs are Read Only (x=0 to 65,535, 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. 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 not process a write

(POKE) to a Peripheral Input Byte. Some input modules are not readable.
