Replacement from EM/EM-II series
This remote module has communication-compatibility with remote I/O for EM/EM-II series, you can use an
existing cable in replacement. But there are differences with lineup of I/O modules, specifications, dimensions, I/O
assignment, and program language, please consider these differences in replacement.
And you must set compression mode according to usage of image slots in EM/EM-II series.
It explains around the content concerning the replacement of a remote system as follows.
4.6.1
Replacement with normal remote method
Figure 4.32 shows the system configuration example of the EM/EM-II series using no image slot. Figure 4.34
shows the replaced system configuration example of the EH-150 series. In the case of EM/EM-II series, it is not
necessary to set I/O assignment for I/O modules. But it is necessary to set I/O assignment "REMOTE 2" for
master module in replaced system with EH-150. Figure 4.33 shows I/O assignment for remote bases of this
replaced system.
Figure 4.34 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 EM/EM-II series in order to postpone the wiring work of slaves. In
this case, please set rotary switch (upper) "E" for master module and all slave modules in order to match
communication protocol. Please turn off high-speed refreshing mode (HS) of a front DIP switch of the master
module and the slave modules.
