Maximum I/O Points When Using Expansion Interface Modules (Remote Master/Slave)
The following table gives the number of digital I/O points and analog I/O points when expansion interface modules (remote
master/slave) are connected to the Plus CPU module and the maximum number of expansion modules and cartridges are
connected to the system.
Notes:
I/O refresh time of the expansion interface remote master/slave modules is stored in D8618 (Refresh Time of Expansion Interface Remote
Master/Slave Modules Current Value) and D8619 (Refresh Time of Expansion Interface Remote Master/Slave Modules Maximum Value).
When the outputs status are changed in a shorter time than the I/O refresh time of the expansion interface remote master/slave modules,
the outputs status may be reflected to the actual outputs. Make sure that the outputs are controlled in a longer time than the I/O refresh
time of the expansion interface remote master/slave modules.
The expansion interface master/slave modules cannot be connected over the Ethernet switch.
