I/O Scans; Alarms; Station Manager - GE PACSystems RX3i User Manual

4.1.3 I/O Scans

The EIS001 module for IEC 104 data exchange does not use a specific I/O Scan Set as defined in the
PME processor Settings tab and in the Ethernet tab for the EIS001 Module.
STOP Mode
In Stop Mode, the IEC 104 Server will respond to General Interrogation requests. The requests will be
serviced with current state data; however, the data will be marked as non-topical to the Client
Station. In STOP Mode, write operations will return a failure to the Client Station.
RUN IO Disable
In RUN IO Disable Mode, the IEC 104 Server will respond as documented for Stop Mode, but the not
topical flag will not be present on the data.
CRU Local Active OFF
In CRU Local Active OFF Mode, (where the client is connected to the IP of the module, not the
redundant IP) the IEC 104 Server will respond as documented for Stop Mode, but the not topical flag
will not be present on the data.
Note: Refer to Option Parameters for more details.
There is no interlock between BIT or WORD functions of individual EIS001
modules. They can reference the same memory space and can accept
contrary commands from various Client stations.

4.1.4 Alarms

The EIS001 generates faults which are logged into the Fault table. A given fault may relate to the
Ethernet interface, or may be specific to the IEC 104 Server functionality. Refer to PACSystems RX7i &
RX3i TCP/IP Ethernet Communications User Manual, GFK-2224 for a description of ETM001-related
alarms.

4.1.5 Station Manager

The RS-232 port on the EIS001 module is set up to be used as a Station Manager. Typically, this is
used for trouble-shooting and administrative purposes.
In addition to standard Station Manager commands, the EIS001 module responds to specific Stat and
Tally Station Manager commands for IEC 104 information. The formats are:
•
stat a. Response displays various operating status. Note the response for technical support.
•
tally a. Response displays various operating counters. Note the response for technical
support.
See Appendix B for examples of these two commands.
For all other commands and responses, refer to PACSystems TCP/IP Ethernet Communications Station
Manager User Manual, GFK-2225.
Each EIS001 will log many conditions to its own Station Manager Log, as well as to RX3i Controller
table as part of Fault Group 0x16.
