Chapter 1 Introduction
1.3 Features
(1) Total economy
It is possible to lead to a reduction in total cost for system including wiring because the standard price of master and
slave modules is reasonable and an affordable twisted cable can be used.
(2) Compatibility with current models
This remote module has communication-compatibility with the remote I/O for EM/EM-II and H-200/250/252B/252C
and the remote I/O MINI for current H-2002/1002/702/302, and you can use an existing cable. Therefore, you do not
need to rewire the cable and the replacement to EH-150/EHV is easy.
(3) Partial and step-by-step replacement
Since both of master and slave modules can be used with current models, it is possible to replace the modules
step-by-step and partially. For instance, a program in CPU can be used without changing even if only a slave module
is replaced, and I/O wiring for slave module is not required simultaneously even if only a master module is replaced.
(4) Fast response and high reliability
The remote refresh time is approximate 2.5ms (setting to high-speed mode (HS) and 256 I/O points). A reliable remote
system can be built because improper communication data is discarded by the reverse double-transmission check
function which has high performance as before.
(5) I/O hold function
Since a slave module has an output hold function and a master module has an input hold function from the remote
slave module, these modules are applicable to the process control.
(6) Easy handling
The cable for these modules is easily-available due to the twist cable and easy to handle.
