CPU Specifications and Operation
Network Configuration and Connections
This section describes how to configure the CPU’s built-in networking ports for either
MODBUS or DirectNET. This will allow you to connect the DL05 PLC system directly
to MODBUS networks using the RTU protocol, or to other devices on a DirectNET
network. MODBUS host systems must be capable of issuing the MODBUS
commands to read or write the appropriate data. For details on the MODBUS
protocol, check with your MODBUS supplier for the lastest version of the Gould
MODBUS Protocol reference Guide. For more details on DirectNET, order our
DirectNET manual, part number DA–DNET–M.

You will need to make sure the network connection is a 3-wire RS–232 type.
Normally, the RS–232 signals are used for for communications between two devices
with distances up to a maximum of 15 meters.
