4.4 Replacement from H-200/250/252B/252C
This remote module has communication-compatibility with remote I/O for H-200/250/252B/252C, you can use an
existing cable in replacement. But there are differences with lineup of I/O modules, specifications, dimensions, I/O
assignment, and support of commands, please consider these differences in replacement.
And you must set compression mode according to usage of image slots in H-200/250/252B/252C.
It explains around the content concerning the replacement of a remote system as follows.
4.4.1
Replacement with normal remote method
Figure 4.15 shows the system configuration example of the H-200 series using no image slot. Figure 4.16 shows
I/O assignment for remote bases of this system. Figure 4.17 shows the replaced system configuration example of
the EH-150 series. In this case, it is necessary to change I/O assignment for master module from "Remote" to
"Remote 2".
Figure 4.17 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.
