When Using The File Register (R, Zr); Setting Of The Network And Station Numbers; Usable Connections - Mitsubishi Electric MELSEC iQ-RJ71EN71 User Manual

Security function
The simple CPU communication cannot be performed when a remote password is set for the module which performs the
simple CPU communication. Clear the remote password setting of the communication destination.
If the IP filter function has been set in the destination, check the setting and correct it if necessary.
If any security function specific to the communication destination (programmable controller products manufactured by other
companies), disable the function.

When using the file register (R, ZR)

When using the file register (R, ZR) for the device on the own station, always assign the device within the setting range. If the
devices are not assigned, an error occurs (error code: 4031), and the simple CPU communication of the setting number which
exceeds the setting range cannot be performed.

Setting of the network and station numbers

When the communication destination is the MELSEC-Q (Ethernet module) or MELSEC-L (Ethernet module), the network
number and station number should be set in the own node settings of the Ethernet parameters.

Usable connections

Up to 64 connections can be used in the simple CPU communication settings. If, however, connection has been used for other
functions, the maximum number of connections is the difference calculated by subtracting the number of connections used for
other function from 64.
