4: Q & A Can I use the Lantronix IAP Device Server with Multi-Master DF1 to link directly to the Ethernet port of a ControlLogix, PLC5/80E, or SLC5/05? No, the Multi-Master DF1 does not do protocol conversion. It only manages raw DF1 that has been encapsulated as is within TCP. The ControlLogix is talking CIP (Ethernet/IP) and the PLC5 and SLC5 are by default talking CSP (port 2222 or AB/Ethernet as it is sometimes called) or CIP if you enable "Multi-hop." None of these PLCs can accept raw DF1 on a TCP socket. There are pros and cons of doing this either way. We have chosen the most generic, widely applicable way to support DF1 with TCP/IP. Does the IAP Device Server with Multi-Master DF1 autobaud? No, you must manually set the baud rate to match your PLC. When I use the Com Port Redirector, why doesn't the baud rate I set for the virtual COM port seem to be accepted by the IAP Device Server? You must manually set the baud rate in your IAP Device Server to match your PLC. The baud rate and other information entered on the computer are not sent to the IAP Device Server. Can I multi-drop PLC with the IAP Device Server with Multi-Master DF1? No, this firmware only supports DF1 Full-Duplex (point-to-point) and not DF1 HalfDuplex (master-to-multiple-slaves). How do I select a cable for different Allen-Bradley PLCs? Micrologix Series Use the same cable as when using the Allen Bradley programming or communications software. SLC 500 Series If the PLC has an RS232 port, you can connect directly using a standard RS232 null modem cable. For the SLC-500 (SLC 5/03, 5/04, 5/05), you can use 1747-CP3 cable. The PLC port must be configured for DF1 communications, not DH-485 Master. PLC5 Series A direct connection can be made to the CH0 port of enhanced PLC5 processors using a standard RS232 null modem cable. The port must be configured for DF1 communications.
