SMC Wireless System
■ Outline
This system is an I/O distributed system which can be wirelessly connected.
It consists of a combination of a base and remote that has a wireless function with the upper-level device.
The base can be combined with an EX600 series I/O unit . Module configuration can be constructed. (See
page 11.)
The base can have max. 128 points input and 128 output. By matching the number of remote I/O points, it
is possible to have up to 1280 points for input and 1280 points for output.
Therefore, the maximum number of I/O points per 1 node can be 1280 points (160 bytes) / 1280 points
(160 bytes) visible from the upper level communication such as a PLC.
By registering the Product ID (PIDs) which are held for each product, the base and remote are
designed to prevent malfunction even when multiple base and remote units are operated in the same
area.
The packet of the wireless transmit and receive data is encrypted. It is therefore difficult to manipulate the
data.
Refer to the Operation Manual for the SMC Wireless System EtherNet/IP, PROFINET type for details.
