Server Idle Timeout -
This parameter gives the idle timeout in seconds for the
Modbus/TCP connection. If SREA-01 does not receive any Modbus/TCP query
within this time the connection will be closed. The default value is 60 seconds.
IP Authentication -
This can be used to configure the IP addresses that are allowed
to connect to SREA-01. Connections from other IP addresses will be blocked.
Example: You want the SREA-01 to be accessible only from the single IP address
192.168.25.99. Input this IP number to the IP number field and use Mask
255.255.255.255.
Note:
When assigning Modbus device addresses to the drives, it is very important to
ensure that two devices do not have the same address. In such a case, abnormal
behaviour of the whole bus can occur and the Master may not be able to
communicate with all present drives on the bus.
Internal Registers
If Internal module registers via Modbus/TCP are enabled, queries sent to that
address will not be forwarded to the Serial Modbus/RTU network; SREA-01 will
respond to these queries by itself.
See chapter
Appendix B: Internal Modbus registers
for a list of the internal registers.
Valid Modbus commands for internal registers:
Note:
The internal registers are also available as an “internal device”, i.e. the
registers can be used on custom pages and as alarms/log entries.
