Description
The IH command is used when the controller is operated as a master (client) to open a handle and connect to a slave (server).

Byte 3 of the slave IP address

Byte 2 of the slave IP address

Byte 1 of the slave IP address
1
Byte 0 of the slave IP address
Notes
See Remarks
If o is omitted, the controller selects
the port starting at 1000
n = 2 is TCP. n = 1 is UDP.
See Remarks
Remarks
All 4 bytes must be assigned for an IP address to be valid.
IHm=? returns the IP address as 4, 1-byte numbers.
Use the following equation to change the 4 byte IP (n0,n1,n2,n3) to a single 32 bit number, n.
n = (n0*2^24) + (n1*2^16) + (n2*2^8) + n3.
When using Modbus, port 502, note that Galil Modbus supports one master per slave.
Opening a Handle
To open a handle, the user must specify:
The IP address of the slave.
(optional) The port number of the slave. If not specified, the firmware will choose a port.
Modbus connections must always be specified as port 502.
(optional)The connection type as TCP/IP or UDP/IP. If not specified, the controller will make a TCP connection.
Issue the IH command on an available handle with the correct settings for IP (n0-n3), port (o) and connection type (p).
See TH to list handle status.
Closing a Handle
Closing a handle is done with the S and T handle identifiers, along with connection type p selector.
IHS => p closes the handle that sent the command with connection type matching > p
IHT => p closes all handles except for the one sending the command with connection type matching > p
For closing handles, use > p where p = -1 closes UDP handles, p = -2 closes TCP handles, and p = -3 closes all handle types
