Galil DMC-3425 user manual Manual Slave IP configuration with HC command

Step 1. Assign IP address to master controller either through IA command or through BOOTP utility in the Galil Software Registry. You may then burn this IP address into the master with the BN in order to keep this address during resets.

Step 2. Place jumpers on each slave controller indicating which slave corresponds to which axes in the system. See section “Step 2. Configuring Jumpers on the DMC-3425”.

Step 3. Determine total number of axes, data update rate, and number of IOC-7007 controllers in the distributed system.

Step 4. Issue the command HCn,m,o,p where n is the total number of axes, m is the data update rate in milliseconds, o is a 1 for UDP communication or 2 for TCP/IP communication and p is the total number of IOC-7007’s in the system. When using UDP communication, the HC command will assign one handle for both commands and QW records. When using TCP/IP communication, the HC command will assign one handle for commands and one handle for QW records. If o is a 3, then TCP/IP is used for commands, and UDP is used for QW records.

Step 5. Poll the operand _HC for success of connection. A response of 1 indicates the command is currently executing, a 2 for a successful configuration and a 0 for a failed configuration or no HC issued.

NOTE: The HC command may take up to 20 seconds to complete due to the time involved in waiting for the BOOTP packets.

Manual Slave IP configuration with HC command

It may be desired to manually assign an IP address to the slaves, while still using the HC command to connect to these slaves. This is possible, but you will need to take into account the addressing scheme the HC command is using, and you must install axis configuration jumpers according to “Step 2.

Configuring jumpers on the DMC-3425”.

When the HC command is initiated, the master will ARP addresses where it expects slave controllers to reside. If no controllers respond to the ARPs, the master will then ‘listen’ for the BOOTP packets from un-assigned slave controllers.

For addressing the slaves manually, the IP address MUST be assigned as follows. This will insure that the HC command will properly configure these controllers based on the master IP address.

Assume Master IP address = m.n.o.p where m, n, o and p is a valid Ethernet IP address. First Slave IP address (Axis B or C) = m.n.o.p+2

Next slave is assigned +2 if previous slave was a single axis (DMC-3415). Next slave is assigned +4 if previous slave was a dual axis (DMC-3425). Slave axes are always assigned addresses based on their first axis. IOC-7007 controllers are addressed as follows:

IOC 1 = m.n.o.p+16 IOC 2 = m.n.o.p+20

For example, in a 5 axis/1 IOC-7007 system with a DMC-3415 A axis Master, a DMC-3415 B axis, a DMC-3425 CD axis and a DMC-3415 E axis the following IP addresses would be set:

Assume Master IP address – 10.10.50.10 B Axis DMC-3415 – 10.10.50.12

CD Axis DMC-3425 – 10.10.50.14

E Axis DMC-3415 – 10.10.50.18
