DMC-1400 Series Command Reference IH ● 103
IH
FUNCTION: Open Internet Handle
DESCRIPTION:
The IH command is used when the DMC-1415, DMC-1416 or DMC-1425 is operated as a
master (also known as a client). This command opens a handle and connects to a slave.
Each controller may have 6 handles open at any given time. They are designated by the
letters A through F. To open a handle, the user must specify:
1. The IP address of the slave
2. The type of session: TCP/IP or UDP/IP
3. The port number of the slave. This number is not necessary if the slave device does
not require a specific port value. If not specified, the controller will specify the port
value as 1000.
ARGUMENTS: IHh= ip0,ip1,ip2,ip3 <p >q or IHh=n <p >q or IHh= >r where
h is the handle, specified as A,B,C,D,E or F
ip0,ip1,ip2,ip3 are integers between 0 and 255 and represent the individual fields of the IP
address. These values must be separated by commas.
n is a signed integer between - 2147483648 and 2147483648. This value is the 32 bit IP
address and can be used instead of specifying the 4 address fields.
IHS => C closes the handle that sent the command; where C=-1 for UDP/IP, or C=-2 for
TCP/IP.
IHN => C closes all handles except for the one sending the command; where C=-1 UDP, or
C=-2 for TCP.
<p specifies the port number of the slave where p is an integer between 0 and 65535. This
value is not required for opening a handle.
>q specifies the connection type where q is 0 for no connection, 1 for UDP and 2 for TCP
>r specifies that the connection be terminated and the handle be freed, where r is -1 for UDP,
-2 for TCP/IP, and –3 for TCP/IP reset
"?" returns the IP address as 4 1-byte numbers
OPERAND USAGE:
_IHh0 contains the IP address as a 32 bit number
_IHh1 contains the slave port number
_IHh2 contains a 0 if the handle is free
contains a 1 if it is for a UDP slave
contains a 2 if it is for a TCP slave
contains a -1 if it is for a UDP master
contains a -2 if it is for a TCP master
contains -5 while establishing UDP handle
contains -6 while establishing TCP handle
_IHh3 contains a 0 if the ARP was successful
contains a 1 if it has failed or is still in progress.
