OPC Server Screens and Fields
Ethernet Adapter
The MOPS communicates with the ICS TRIPLEX controllers through the Ethernet adapter. This
text box displays the ID of the adapter used for communications with the controllers. This field
cannot be changed during run-time. If your computer has more than one Ethernet adapter, and the
controllers are on a network which is connected to an adapter which does not have the ID of zero
(0), then you will need to configure MOPS to point to the correct adapter ID. This can be done by
using the registry and changing the Adapter ID key in the MICON OPC Server group in the
registry. This change in Adapter ID should be effected only when the MICON OPC Server is not
running on the computer.
Ethernet Address
This text box displays the six byte Ethernet address for the adapter chosen for
communications with the controllers. Once again, the Ethernet address field cannot be
changed by the user without changing the Adapter ID item in the registry.
Settings:
Refresh Rate
This box tells the MOPS the refresh rate to use in the refresh mode when reading tag values from
the ICS TRIPLEX controllers. The ICS TRIPLEX controllers support a mode in which a tag list is
sent to controllers by a host device (such as the MOPS). Once such a tag list has been sent to the
controllers, they automatically send the values for those tags to the host at the refresh rate. This is
called the refresh mode.
The ICS TRIPLEX controllers support multiple refresh taglists (one for each host). This allows for
MOPS to be running on multiple computers at the same time. MOPS checks the destination
address of all packets from the controllers and processes only those packets destined for its
computer.
Settings:
Enable Time Download
ICS TRIPLEX controllers receive time of day information from host computers. If a SPARC
based A/S View system is present on the network, then MOPS’s “Time Download”
capability should be disabled. On any network, only one computer (MOPS or SPARC)
should be enabled for time download to controllers.
Settings:
Allow writes to tags
If it is desired to disallow OPC clients to write new values to tags on controllers, then this
check box must not be checked.
