ZMIO310 Vertical Bus Expansion Module User Manual V1.0
6.4.1.
Expansion Submodule Address Allocation
For example: the local post-level interface of the ECAT communication module (ZMIO310-
ECAT) is sequentially connected to 3 input modules (ZMIO310-16DI), 2 output modules
(ZMIO310-16DO or ZMIO310-16DOP), 1 AD module (ZMIO310-4AD) and 1 DA module
(ZMIO310-4DA), and the slot No. and device No. are both 0 by default.
The address of the expansion sub-module is numbered from 0, and the address of the
expansion sub-module closest to the coupler module is 0, the addresses of other sub-
modules are sequentially accumulated by 1, that is, the addresses of the DI modules are
0, 1, and 2 respectively, and the addresses of the DO modules are respectively 3, 4, AD
address is 5, DA address is 6.
Then, data dictionary is created according to above:

Please refer to Chapter 6.3 for dictionary details.
⚫
The data dictionary corresponding to the address 0~6 will only be created when the
corresponding expansion module is connected, that is, it will not be created when
other modules are connected.
