Application-Specific FAQ
Q: Can the 1761-NET-AIC connect a MicroLogix 1100 to a PC running RSLinx Classic?
A: Yes. Connect the 1761-NET-AIC between the MicroLogix 1100’s DH-485 port and the PC’s RS-232 COM port. Configure RSLinx Classic with the “DH-485” driver and select the appropriate COM port and baud rate.
Q: How many 1761-NET-AIC adaptors can exist on a single DH-485 network?
A: The DH-485 network supports up to 32 nodes total. Each 1761-NET-AIC occupies one node address, so the number of adaptors is limited by your total node budget.
Q: Is the 1761-NET-AIC compatible with SLC 5/05 processors?
A: The SLC 5/05 has a built-in Ethernet port and typically does not require the 1761-NET-AIC. However, it can be used to bridge the SLC 5/05’s RS-232 channel to a DH-485 network segment if required by the system architecture.
Q: What cable is required to connect the 1761-NET-AIC to a MicroLogix controller?
A: Use the 1761-CBL-PM02 (mini-DIN 8-pin to DB-9) or 1761-CBL-AP00 cable depending on your MicroLogix model’s communication port type.
Q: Does Konmask.com provide a warranty on this part?
A: Yes. All units carry a 90-day functional warranty. Extended warranty options are available — contact support@konmask.com for details.
