IRQ (all cards) identifies the interrupt setting of all DH+ interface cards
installed in the computer. This selection should match the IRQ settings
on
all
of the interface cards.
Assigning an interrupt to the interface card(s) improves overall computer
performance somewhat. Any time one of the cards receives an input, it
generates an interrupt recognized by Lookout
Direct.
Caution
Be sure to verify that no other drivers or cards are mapped to the selected
memory address or use the same interrupt.
Allen-Bradley Ethernet Interface Parameters
The Ethernet Interface selection enables direct communication between
your computer and a PLC using a standard Ethernet network. The
following diagram shows an AB_PLC5 configured for Ethernet
communications.
IP address specifies the Internet protocol address of the PLC. An Internet
protocol address consists of four numbers, separated by periods. Each
number ranges from zero to 255 decimal. Thus, a typical Internet address
might be 128.7.9.231. Ensure that the IP address you enter matches the
Internet protocol address of the PLC your object represents. You can also
enter the IP address by name.
