6.3 AMCI Modbus TCP Memory Layout

The SMD23E2 and SMD24E2 has a starting Input Register address of 0 and a starting Output Register
address of 1024. Input Registers hold the data from the driver while Output Registers hold the data to be writ-
ten to the unit. Figure T6.1 shows how an SMD23E2 or SMD24E2 is mapped to the Modbus data reference.

6.4 Supported Number of Connections

All SMD23E2 and SMD24E2 units support six concurrent connections. When connections exist, the Network
Status (NS) LED on the back of the unit will flash green. The number of blinks indicate the number of active
connections. There is a two second break between groups of flashes.
