3.6 IEC 104 Server Configuration

The IEC 104 configuration settings determine how the EIS001 will be expected to interact with its IEC
104 Client(s). The IEC 104 Server has only one instance of data that it serves.
As an IEC 104 Server, the EIS001 will have one profile, and it must be configured through the RX3i
CPU before it can operate on the IEC 104 network. The COMMREQ outlined in Chapter 6is used for
this purpose. It conveys all IEC 104 Server parameters from the RX3i CPU to the EIS001. The
COMMREQ is executed only once to initialize the EIS001. Refer to Appendix A for the status area
definition for diagnostics information for the IEC 104 Server module. Also refer to Appendix D for the
IEC 104 Server device profile as applicable to the EIS001 module.
Once configured and connected to its IEC 104 Client(s), the EIS001 will exchange data automatically
per its configuration and that of its Clients.
RX3i CPU memory needed for IEC 104 Server data can optionally be configured into the EIS001
module using a single startup COMMREQ, as documented in Chapter 6. The Server configuration is
permitted to use %I, %AI, %Q, %AQ, %R, %W, %M, %T and %G memory types, as documented in
Chapter 6. Ranges should be selected so as to accommodate the amount of data involved, but not
overflow the end-point of the memory type.
The Server configuration file also includes parameters to define an area of Controller memory for
Client station-Server communication status, if required. The Parameters for Server Status Space is
defined in Section 6.4.3.
As mentioned above, the EIS001 may be connected to separate LANs using its two Ethernet Ports
(marked Port 1A and Port 1B). The two ports are independent and should be connected to the same
LAN. Whenever both ports are connected to active LANs, the Clients on one LAN will typically impose
different real-time demands on the EIS001 than the Clients on the alternate LAN. Nonetheless, all
traffic is handled per the Configuration of IEC 104 Server Parameters Using COMMREQ instruction
detailed in Chapter 6.
