(2) Remote net Ver.2 mode and remote net additional mode
The table below lists the maximum number of connected modules of when a system is configured only with Ver.2-
compatible slave stations. For the modes, refer to Page 43, Section 3.6.2.
64 modules of a remote I/O station, remote device station, local station, standby master station, and intelligent
device station can be connected in total for one master station. Note, however, that the following conditions must
be satisfied.
