Wiring precautions
When wiring terminal wiring, avoid binding with cables with strong interference
signals, such as power lines, and route them separately.
In the case of severe electromagnetic interference on site, shielded cables should
be used to improve the anti-interference ability.
The expansion sub-module must first be connected to an independent power
supply, or powered on at the same time as the ECAT communication module.
It is not recommended to use the same power supply for the ECAT communication
module and the expansion sub-module. Especially in the case of severe
electromagnetic interference on site, different power supplies must be used and
they do not share a common ground.

Address description
ECATThe local extension interface of the communication module is randomly
connected to 4AD/ DA extension submodule, the number of connected extension
submodules should beDoes not exceed8Pc.ECATAfter the communication module is
powered on,Will scan the local extension interface, and forScannedEach expansion
submodule is assigned an address.
Such asECATThe communication module is sequentially connected to a 4AD expansion
submodule and a 4DA expansion submodulePiece. 4AThe address assigned to the D
expansion submodule is 1, and the address assigned to the 4DA expansion submodule is
2..According to the access ECAT communication moduleTo determine the address in order,
the first expansion submodule to be accessed is1. The expansion submodules expanded
afterwards are incremented one by one. This address is used for the address specified by
the writer of the subsequent SDO information.The type of expansion sub-module that is
connected does not affectThe address assigned by the ECAT communication module.

ZMC406As an EtherCAT master station, ZMIO300-ECAT is used as a slave station to
expand one4AD extension submodule and one4DAThe expansion submodule is used as
an example, and the description is as follows:
Use the Basic programming language to program the ZMIO300 expansion
