Data Exchange

The transferred data is composed of command, confirmation and response telegrams.
Control
The control software (client) sends a command to the IDENTControl (server). The
IDENTControl then sends confirmation of receipt (not with MODBUS TCP/IP). The
IDENTControl sends the response after the command is executed.
The IDENTControl can send multiple responses for enhanced commands. However, only a
single confirmation is sent.
A command consists of the telegram length (TCP/IP und MODBUS TCP/IP only), the
command code, the channel associated with the read/write head (ident channel), a specified
number of parameters and the data relating to the command.
The confirmation consists of the telegram length (TCP/IP and MODBUS TCP/IP only), the echo
of the command code, the echo of the ident channel, the status FFh and the reply counter.
The response consists of the telegram length (TCP/IP and MODBUS TCP/IP only), the echo of
the command code, the ident channel, the status, the reply counter and the requested data.
Note!
Power Supply Reset
The IDENTControl communicates via one of the following protocols:
TCP/IP
■
MODBUS TCP
■
Ethernet/IP
■
PROFINET IO
■
The Java applet of the IDENTControl web function also uses the TCP/IP protocol. To change
the protocol that the IDENTControl uses to communicate, reset the power supply.
