The MICREX-SX Communication Middleware (NP4N-MDLW) is a local/remote data access server compliant with OPC
Data Access 2.0 proposed by OPC Council. It provides connection environment for clients (applications created in Visual
Basic, Visual C++, etc.) and MICREX-SX (global variables).
(Hereinafter, the MICREX-SX Communication Middleware may be simply referred to as SX_MDLW.)
SX_NDLW is an interface for connecting between the MICREX-SX SPH system (data source) and applications (data
users) called clients.

Note)
Note: SPS is not currently supported.
OPC clients and the OPC server are connected using automation or custom
interface. For example, automation interface is used for Visual Basic and
custom interface is used for C++.
For interfacing between SX_MDLW
(machine equipped with SX_MDLW) and
MICREX-SX system, use Ethernet, RS-
232C, FL-net, SX bus or modem.
