can not used.
2.11.2 Special function module address
Since you can attach multiple special function modules to a single base unit each module needs
to have a unique identifier so that you can address it to transfer data to and from it. Each module
is automatically assigned a numerical ID in the range from 0 – 7 (you can connect a maximum of
8 special function modules). The numbers are assigned consecutively, in the order in which the
modules are connected to the PLC.
Special function module addresses are not assigned to the following products:
–
Input/output powered extension units (e. g. FX
2N-32ER-ES/UL or FX2N-48ET-ESS/UL)
–
Input/output extension blocks (e. g. FX
