4.5.4 Replacement from Remote I/O MINI with mode-0
Mode-0 of remote I/O MINI is a mode that uses the remote input in 352 points (704 points in the case of using
image slots).
Transfer command (TRNS1, QTRNS1) or a handshake program was necessary in the ladder program for handing
over the data Remote I/O MINI and CPU while a lot of remote I/O numbers were able to be used.
Figure 4.29 shows the system configuration example of Remote I/O MINI with mode-1 for Large H series.
Figure 4.31 shows replaced system configuration example with compact remote.
In this case, it is necessary to change I/O assignment of master module from "Word 4W/4W" to "Remote 2".
Please set I/O assignment “X16”, “Y16” for all input modules and output modules on slave bases as shown in
Figure 4.30, and change I/O numbers in program from internal outputs for communication area to remote I/O
numbers on remote slave bases by using I/O No. batch change function.
In the case of replaced compact remote system, it is not necessary to use transfer command (TRNS1, QTRNS1)
or handshake program, but you can use remote I/O numbers directly in ladder program. Please delete these
transfer command or handshake program for normal operation of compact remote system.
Figure 4.31 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 set the same value of first channel number and number of occupied channels with Figure 4.31, and
please turn off high-speed refreshing mode (HS) of a front DIP switch of the master module and the slave
modules.
