Modbus TCP
Modbus TCP allows to read the status of the network and the device.
The Modbus TCP server is accessible on Modbus TCP standard port 502.
The Modbus TCP server can only serve one client at once.
Only read commands to input registers (function code 4) are supported. The read
command consists of 16 bit words. The following memory map shows the availa-
ble data of the switch. The address consists of the start address 30001 (decima l)
and an offset. When reading out using an INSYS Device App (icom Data Suite or
Monitoring App) the addresses in the
INSYS-Adr. (dec)
column must be used as
register address for an input register. Names and description are ASCII -coded and
one word contains two characters. Not used characters are filled with 0x00.
The offsets are displayed as hexadecimal figures in the following table.
