Replacement from Remote I/O MINI of Large H series
Table 4.2 shows the outline of replacement from Remote I/O MINI of Large H series to compact remote of EH-150
series. According to operating mode (0 to 3) of master module (REM-MMH), Please set I/O assignments for master
and I/O modules on slave bases in replaced compact remote system as shown as Table 4.2.
When the number of mounting slots exceeds 16 and connected number of the slave stations exceeds 8, it is not
possible to replace compact remote system and examine the replacement with optical remote system and so on.
Moreover there is no communication modules that communicate between CPU and remote system like Remote I/O
MINI slave (REM-LMH) and H-200 slave (REM-LH2). So, examine replacement with CPU linkage modules
(EH-LNK, EH-OLNK) in this case.

Replacement from Remote I/O MINI with mode-1
Mode-1 of remote I/O MINI is a mode that uses the remote output 128 points. Figure 4.21 shows the system
configuration example of Remote I/O MINI with mode-1 for H-300/700/2000/302/702/1002/2002/4010.
Figure 4.22 shows replaced system configuration example with compact remote.
In this case, it is necessary to change I/O assignment of master module from "Word Y8W" to "Remote 2".
Please set I/O assignment "Y16" for all output modules on slave bases, and change I/O numbers to its on remote
slave bases in program by using I/O No. batch change function.
Master module (EH-TRMME) of replaced system must be mounted on slot from 0 to 7 of base unit because
master module is treated as remote module. Moreover one CPU allows maximum 4 master modules in remote
system, it is necessary to change I/O assignment of master module to "Word 4W/4W" to use the number
exceeding 4 of master module per CPU. But in this case, it is necessary to make the number of output modules
below 4 per master module.
Figure 4.22 is an example of replacing all of master and slave modules with the EH-150 series. It is also possible
to leave all or partially slave modules like the H-200 series in order to postpone the wiring work of slaves. In this
case, please turn off high-speed refreshing mode (HS) of a front DIP switch of the master module and the slave
modules.
