Module 9071 Find the string length
The control finds the length of the string in a selectable string memory (S0 to
S99).
Call:
PS K/B/W/D/S<String no. or string>
CM 9071
PL B/W/D <Length of the string>
Error recognition:
Marker Value
NN_GenApiModule 0
Error (M4203)

NN_GenApiModule 2
ErrorCode (W1022)
Module 9072 Copy a byte block into a string
The control copies a byte block from a PLC word memory into a PLC string (S0
to S99). The control does not check whether the byte block consists of valid
ASCII characters. The module always copies the entire programmed length of
the byte block, regardless of any string-end code (0x00) in the byte block. The
control automatically sets a string end code (0x00) after the last copied byte.
If there are any ASCII special characters in the copied byte block, the contents
of the string may not be displayed in the PLC diagnosis correctly.
Call:
PS K/B/W/D <Start address of byte block>
PS K/B/W/D <Length of byte block>
PS K/B/W/D <PLC string>
CM 9072
