3. To create a new connection, click on Add on the "Connection" tab.
ETCN004
4. Specify a name for the connection.
To enable an application to communicate with a control system via the
ETC−MMI Gateway, each connection must be assigned an unambiguous
name. You can choose any name. Assign e.g. consistent names "ETC0",
"ETC1" ... or application−specific names "ramp", "laser control" etc. A
name can contain up to 31 ASCII characters ("A ... Z", "a ... z" , "0 ... 9").
5. Select a connection type:
ƒ UDP connection for ETCHx control systems
Ethernet communication via DPR/UDP/IP protocol.
ƒ PCI connection for ETCPx control systems
DPR communication via a WDM driver (ETCPC.sys, in the scope of supply
of the ETCPC).
6. Enter a communication parameter in the "IP address" field:
ƒ ETCHC = IP address (¶ 28)
ƒ ETCPC = Index of the PCI cards (indexes of the PCI cards are in the range
0 ... 9 and are automatically assigned by the driver. The first ETCPx has
the index 0).
7. Close the dialogue via OK.
Your entries are saved in the file "mmigtway.ini" (¶ 283). If a connection
with the same parameters already exists, the error "Gateway cannot
change the parameter" is reported.
