Description
GIP ADDR, MASK, GATE
The GIP_ADDR instruction copies the CPU’s IP address into ADDR, the
CPU’s subnet mask into MASK, and the CPU’s gateway into GATE.
SIP ADDR, MASK, GATE
The SIP_ADDR instruction sets the CPU’s IP address to the value found
in ADDR, the CPU’s subnet mask to the value found in MASK, and the
CPU’s gateway to the value found in GATE.

Note
•
In order to use the SIP_ADDR instruction, the
"IP address data is fixed to the values
below and cannot be changed by other means"
checkbox must be unchecked. This
configuration checkbox is located in the "System Block", "Communication" node in the
"Ethernet" field.
•
The IP address, subnet mask, and gateway values are written to persistent memory.
