398 Module - eIO

settings. This identifier is also required so that eKERNEL can respond

with the appropriate configuration settings.

• eKernel address

Defines the IP address of eKERNEL. Use the special value *LOCAL

to refer to the same address as the system where eIO resides. In a

single-computer environment the *LOCAL value is usually specified,

because eKERNEL and eIO both share the same network adapter.

When eIO is running on a different computer, the IP address of the

eKERNEL must be specified.

• eKernel port

Refers to the port number eKERNEL listens to for that specific eIO

instance. This port is defined in the eKERNEL_TCPCLIENT table.

• Log drive

Specifies the drive letter where logging files must be stored.

When all parameters are correctly specified, the eIO contacts the

eKERNEL application, producing the log information shown in Figure 138

"Logging information for eIO" (page 398).

Figure 138

Logging information for eIO

Once connected to eKERNEL, the eIO module requests its configuration.

This is performed through a configuration request. The eKERNEL fetches

the configuration from the IO_MODULE, eIO_AI, eIO_DI and eIO_DO

tables and responds with all relevant parameters that are needed for

eIO to continue processing. Figure 139 "eIO configuration request and

response" (page 399) shows the configuration request and the response

eKERNEL sends back.
