It determines whether to connect between the two and communicate according to whether other side returns to the mode of an an equal amount of data packet, and determine delay
Time.
Specifically, the process of configuration address service is provided in TCP/IP, such as based on the centralized management program of TCP/IP stack
It is that work station distributes a group address automatically that DHCP, which can be used, and the dynamic allocation of this IP address are by one equipped with DynamicHost
The Lu device or host of configurator is completed.Use operation DHCP service windowsNT/200Oserver as DHCP service
Device.Network administrator is the range that each subnet establishes a valid ip address in the server, is concurrently set and IP address phase
The subnet mask of pass, the internet default gateway DNS and Windows name Service, the information such as address of server.DHCP permits simultaneously
Perhaps one lease time is set for each IP address, if client computer stops using the IP address of distribution, the rent of the address
It will about stop, and become the address that can be assigned again.
When computer logs on on local area network, Dynamic Host Configuration Protocol server automatically will distribute unique IP address, name for it
It can be program or equipment for BootP, but must be run on the host for possessing only IP address, router can be counted as
It is a DHCP equipment, phychology net hub is served as in its one end, and the other end needs manual assignment host name and domain name, to check
The IP address and relevant information of DHCP distribution can run IP configuration order in the case where entering MS-DOS mode.
When power supply unit breaks down or scraps and stop using the address, the lease of the address stops, and becoming can be again
The address of appointment.

Wherein, the control mode of relay is set as distant place control and local two kinds of control, wherein distant place control by PC or
Person PLC is controlled by way of communication with order, and when receiving close commands, relay is closed, and receives return command
When, check return delay time, be delayed after the identical time, relay return, upon return between be 0 when, relay be in close
Lock status cannot return, and restore factory default 1 for controlling breaker and will cause at this time；Local control is using gauge internal
The control of some electrical parameter, controls the response of alert if as setting up an office to one, when the alarm signal of trigger relay generates,
Check that relay operates delay time, when being greater than the relay running time, if alarm signal exists, relay running,
If alarm signal disappears, relay is failure to actuate；After relay running, when alert if disappears, check that relay involution is prolonged
When the time, be greater than involution delay time after, if alarm signal is not present, relay return, if alarm signal reappears, relay
Device continues to be closed；By running delay and return delay, make warning function have hysteresis I, avoid frequently missing in critical state value
Report.
