Lookout
Direct
uses the AB object classes to communicate with the
Allen-Bradley family of PLC controllers using a variety of interfaces.
Lookout
Direct
can communicate with a member of the PLC-2 family in the
following ways:
• Through a Data Highway Plus (DH+) connection to an Allen-Bradley
1785-KA3 PLC-2 adapter module using an Allen-Bradley 1784-KT,
1784-KTx, or 1784-PCMK card, or an S-S Technologies 5136-SD
direct-link interface card installed in the computer,
• Through the serial port using an Allen-Bradley KF2 module (which
converts serial DF1 to DH+) to an Allen-Bradley 1785-KA3 PLC-2
adapter module, or
• Through a direct DF1 serial connection to the PLC programming port.
LookoutDirect can communicate with a member of the PLC-5 family in the
following ways:
• Through a direct Ethernet connection to the PLC AUI port,
• Through a direct DH+ connection using a 1784-KT, 1784-KTx,
1784-PCMK, or 5136-SD card installed in the computer,
• Through the serial port via a KF2 module which converts serial DF1
to DH+, or
• Through a direct DF1 serial connection to the PLC programming port.
LookoutDirect can communicate with a member of the SLC-500 family in
the following ways:
• Through a direct DH+ connection using a 1784-KT, 1784-KTx,
1784-PCMK, or 5136-SD card installed in the computer,
• Through the serial port via a KF2 module which converts serial DF1
to DH+,
• Through the serial port using an Allen-Bradley 1747-KE card
(which plugs into the SLC chassis and converts DF1 to DH 485),
• Through the serial port using a stand-alone Allen-Bradley 1770-KF3
communication interface module which converts DF1 to DH 485,
• Through a direct DF1 serial connection to a SLC 5/03 or SLC 5/04
programming port, or
