Overview
The KLINKMANN OMRON Ethernet Direct DAServer (hereafter referred to as the
“OMRON Ethernet DAServer” or “DAServer” or “DASOmronEth” throughout the
remainder of this user’s guide) is a Microsoft ® Windows ® application program that acts
as a FINS message communications protocol server. It allows other Windows application
programs access to data from OMRON PLCs (also referred to as devices) over the
OMRON Ethernet FA (Factory Automation) network.
The OMRON Ethernet Direct DAServer requires an Ethernet card and TCP/IP protocol
installed on the computer to communicate with the Ethernet network. The OMRON
Ethernet Direct DAServer can access to data from Controllers connected to the Ethernet
System directly (with Ethernet Unit installed) or from Controllers interconnected to
Ethernet System through SYSMAC LINK network or any other OMRON FA network
(through PC Gateway - an OMRON Controller which has multiple Communications Units
mounted, including the Ethernet Unit, and therefore that belongs to two networks and can
thus function as an interface between them). The OMRON Ethernet Direct DAServer
supports the Controller Memory Areas accessible by FINS commands.
No additions to Controller’s user program are needed if OMRON Ethernet Direct
DAServer is used in a poll (normal) mode, i.e. the DAServer sends read or write FINS
command to Controller and Controller responds with corresponding response. The
OMRON Ethernet Direct DAServer supports also the possibility to receive “unsolicited”
data from Controller – in this case some additions in Controller program are needed. The
DAServer “slave” mode can be established – at communication start-up DAServer
requests data one time and after it - only unsolicited data can be received from Controller.
At same time the writing of new values to Controller is still possible.
The OMRON Ethernet Direct DAServer can access to data from CS1/CJ1, CV-series and
C200HX/C200HG/C200HE PLCs (directly from Ethernet network or inter-networked from
other OMRON FA networks) as well as from C-series and CQM1 PLCs (only inter-
networked from other OMRON FA networks).
While the OMRON Ethernet Direct DAServer is primarily intended for use with
Wonderware InTouch ® (Version 7.11 Patch 02 and later), it may be used by any
