5.6.2.2.16 Class 172 (0xAC) Output Fieldbus Variable UDINT
PLC output byte 1..128
Max. instance: 128
5.6.2.2.17 Class 173 (0xAD) Output Fieldbus Variable UDINT
PLC output byte 1..128
Max. instance: 128
Starts with 2 bytes offset
(the 2nd and 3rd UINT (class168 / instance 2 and 3)
= 1st UDINT (class173 / instance 1) etc.)

Brief description of the attribute
Save dynamic created instances in non
volatile memory (after power up all
saved instances are automatically
created )
0: save no dynamic instances
1: save dynamic instances
Defines the number of bytes from the
PLC-fieldbus-variables (inputs) which
will be added to the assembly object
(this count will be added to the consu-
med path – assembly instances 1..3)
Defines the number of bytes from the
PLC-fieldbus-variables (outputs)
which will be added to the assembly
object (this count will be added to the
produced path – assembly instances
4..9)
