Network Configuration

9.5.2.1 Register 0x1028 – IP Configuration
This register contains information about the set IP configuration.
Possible values:
1 = BootP
2 = DHCP
4 = Fixed IP address
9.5.2.2 Register 0x102A – Number of Established TCP Connections
This register supplies the number of established TCP connections.
The maximum number of MODBUS TCP connections is 1000.
9.5.2.3 Register 0x1030 – MODBUS TCP Socket Timeout
This register contains the timeout value for the TCP sockets.
This value is given in units of 100ms (ticks). A new value is accepted only for
new connections which have not yet been established. In the event of any
changes, the already established connections will continue to operate using the
previously set timeout value.
9.5.2.4 Register 0x1031 – MAC Address for ETHERNET-Interface 1 (eth0)
This register provides the MAC address for the first ETHERNET interface (eth0).
MAC may also provide a partial result.
9.5.2.5

Register 0x1037 - MODBUS TCP Response Delay

This register saves the value of the MODBUS response delay.
This value is specified in ms units. The maximum delay is 32 ms, default value is
0 ms (no delay).
Transmission of the response to a MODBUS request is delayed from the time of
processing (read and/or write register values) by the time set. In the meantime,
incoming requests can only be processed when the previous response is sent. For
MODBUS UDP, this applies to all requests and for MODBUS TCP, for each
connection. The actual length of time between a MODBUS request and the
associated response depends on the number of parallel requests overall system
utilization; it is always greater than the response delay set. Changes to the
response delay become effective immediately for each subsequent request.
