IEC 104 Communications Start-up

The EIS001 module will power up and signal the user program through LIS bit 11 that it is
ready to receive the configuration parameters as defined in the ST block. LIS bit 11 and LIS
bit 13 (LAN OK) are used together in the user program to execute the one-shot signal to
configure the module with its parameters.
LAN Interface Status (LIS) bits 10, 11, and 12 are reserved for use with Ethernet applications.
Only LIS bit 11 is used with the IEC 104 Server; reference the status information below for
operational details.
