2.3.2 Instructions for System Configuration
(1) high speed expansion I/F module
The high performance XGB PLC supports the high speed expansion I/F to enhance the expansion module
processing speed.
This section describes the instructions to configure the system by using the high speed expansion I/F modules
and the existing expansion modules.
- The existing XGB expan
sion· communication· special modules can be commonly used and the high speed
expansion I/F module that cannot be supported by the XGB basic unit are available.
- In the case of expansion communication modules, a total of 4 expansion communication modules can be
mounted in the order of installation; 2EA of high speed I/F communication modules, 2EA of the existing
communication I/F modules.
- In the case of the high speed expansion module, it acts as the high speed expansion I/ only when it is installed
in 1-stage or 2-stage.
- When more than two high speed expansion modules are installed, only the modules mounted in 1-stage, 2-
stage act as the high speed I/F; for the modules mounted in 3-stage or more, they works equally to the
existing expansion modules or does not work depending on the corresponding modules.
- The high speed expansion I/F modules cannot be installed behind the normal expansion modules. Accordingly,
when using the high speed expansion modules and the existing normal expansion modules by mixture, the
existing ones should be installed behind the high speed ones.
- The below table represents the example of the system configuration using the high speed expansion modules
and the existing normal expansion modules.
