Address 8:
Notes:
1.The address setup of the extension module must be before powering on. Modification when powering
on will be ineffective.
2.Freely connection with CPU and expansion , do not care the power supply type of CPU and
extensions ,that means the AC type module also can be connected with the DC type module or AC type
expansion module also can be connected with DC type CPU.
3.If the communication is established between CPU and extensions , the indicator on the top of the
extensions’ house will turn to RUN(green color)(If the LED is red, that means the CPU cannot get
communication with it).
4.If more than one expansion module connect to CPU at the same time ,the address of expansion module
must be different each other, otherwise the system(CPU+expansions) would run abnormal, but if the
expansion already has each own separately address, then the installation sequence of the expansion is
not important anymore, for example you can let the expansion with address 8 as the first one with CPU.
