Configuring the DL06’s Comm Ports
This section describes how to configure the CPU’s built-in networking ports for either
MODBUS or
Direct
NET. This will allow you to connect the DL06 PLC system directly to
MODBUS networks using the RTU protocol, or to other devices on a
Direct
NET network.
MODBUS masters on the network must be capable of issuing the MODBUS commands
to read or write the appropriate data. For details on the MODBUS protocol, please refer
to the Gould MODBUS Protocol reference Guide (P1–MBUS–300 Rev. B). In the event
a more recent version is available, check with your MODBUS supplier before ordering the
documentation. For more details on
Direct
NET, order our
Direct
NET manual, part number
DA–DNET–M.
NOTE:
For information about the MODBUS protocol see the Group Schneider Web site at: www.
schneiderautomation.com. At the main menu, select Support/Services, Modbus, Modbus Technical Manuals,
PI-MBUS-300 Modbus Protocol Reference Guide or search for PIMBUS300. For more information about the
Direct
NET protocol, order our
Direct
NET user manual, part number DA–DNET–M, or download it free
from our Web site: www.automationdirect.com. Select Documentation/Misc./DA-DNET-M.
