Protected Typed Logical Read With 2 Address Fields - Wieland samos PRO Manual

Table 57: Read address structure of PLC-5 input
Address Data type Number
$N57:x
$N167:x
Example: "$N57:10" and "Total Transaction = 24" address elements 11 to 34 correspond to bytes 20
to 66 of assembly instance 57.
Note: Byte 67, which is not specified in assembly instance 57, is also transferred.
Note: The position of the word data with system state and system mode are dependent on the requ-
ested amount of data "x".
