12.5.4 Process data assignment for "SSI mapping standard 1" (I4104 = 1)
)
Note!
"SSI mapping standard 1" and "SSI mapping standard 2" differ in
the arrangement of the input/output bytes and the control byte.
l Please read the documentation for the controller, in particular
for the CAN−IN function block, to see which mapping is to be
used for communication.
This mapping is required for encoder value evaluation using standard 9300
controllers. The encoder value is provided as DWORD.
Setting index I4104
h
= 1 adapts the input/output byte assignment for
communication with Lenze 9300 controllers.

For data input / output, four bytes are available which are transmitted (Rx PDO) or
output (Tx PDO) by PDOs.

Note!
Input and output data get lost when the mains supply is switched
off/on; they are not stored!
