Overview
Extra communications
port
All DL405 CPUs offer at least two built-in
communication ports. (The D4-450 and
D4-454 both have four ports.) However,
if even more communication ports are
needed, additional Data Communication
Modules can be added. As an extra
communication port, the DCM has specifications identical to port 1 on the DL405
CPUs. Whatever can be connected to port
1 of the DL405 CPU can be connected to
the DCM, just make sure the device has
a DL405 compatible driver. This allows
additional connections of devices, such as
operator interfaces, personal computers,
etc. Since the DCM does not require
any programming, you can set the DCM
communication parameters, connect the
cables, and start transferring data.
The DL405 Data Communication Module
(DCM) is a general purpose communications interface for the DL405 family of
PLCs. This module is primarily used for
three reasons:
• Extra general purpose communications port
to connect a personal computer, operator
interface, etc.
• Network interface to a DirectNET network
• Network interface to a Modbus network using
the RTU protocol as slave.

Serial Data Communications Module
DirectNET network
interface
The DCM can be used as a network
interface for applications requiring data
to be shared between PLCs, or between
PLCs and an intelligent device such as a
host computer. The DCM connects easily
to DirectNET. This network allows you to
upload or download virtually any type of
system data including timer/counter data,
I/O information, and V-memory information from any of our PLCs or compatible
PLC. The DCM allows the DL405 PLC
to function as a master or a slave of
DirectNET.

Network Master - The DCM allows the
DL405 to serve as a master of a DirectNET
Network. The DCM takes communication
requests issued from the PLC program
(the network part of the program can be
very simple, as few as seven words) and
automatically converts these requests into
network commands to read data from or
write data to another PLC on the network.
This capability also allows a peer to peer
configuration of two DL405 systems with
DCMs. For other options, consider the
H4-ECOM100 module.
Network Slave - All DL405 CPUs have
a built-in network slave port. If this port
is occupied, a DCM can be added to
provide an additional network slave
port. In this case, the DCM “listens” to
the network for any messages containing
the DCM’s address. The DCM deciphers
the network commands, carries out the
request to read or write data, and sends
confirmation and/or information to the
master station. Since the DCM does not
require any programming, you can set
the DCM communication parameters,
connect the cables and start transferring
data.

The DCM can be used as a slave
station interface to connect your DL405
system to the Modbus network using the
Modbus RTU protocol. The host system
must be capable of issuing the Modbus
commands to read or write the appropriate data.

Check the Power Budget
Verify your power budget
requirements
This logo is placed next to I/O modules
that are supported by the ZIPLink connection systems.
Your I/O configuration choice can be
affected by the power requirements of the
I/O modules you choose. When determining the types and quantity of I/O
modules you will be using, it is important
to remember there is a limited amount of
power available from the power supply.
See the I/O module specifications at the
end of this section.
The chart on the opposite page indicates
the power supplied and used by each
DL405 device. The adjacent chart shows
an example of how to calculate the power
used by your particular system. These
two charts should make it easy for you to
determine if the devices you have chosen
fit within the power budget of your system
configuration.
Calculating your power
usage
The following example shows how to
calculate the power budget for the DL405
system. The example is constructed around
a single 8-slot base using the devices
shown. It is recommended you construct a
similar table for each base in your system.

C

CURRENT REQUIRED
If the I/O you have chosen exceeds the
maximum power available from the power
supply, you can resolve the problem by
shifting some of the modules to an expansion base or remote I/O base (if you are
using remote I/O).

Warning: It is extremely important to calculate the

budget, the system may operate in an unpredictable
manner which may result in a risk of personal injury
or equipment damage.

Use ZIPLinks to reduce
power requirements
If your application requires a lot of relay
outputs, consider using the ZipLink AC
or DC relay output modules. These
modules can switch high current (10A)
loads without putting a load on your base
power budget. Refer to Wiring System for
DL405 PLCs later in this section for more
information.
OTHER
1. Using a chart similar to the one above, fill in column 2.
2. Using the tables on the opposite page, enter the current supplied and used by each device (columns 3 and 4). Pay special attention to
the current supplied by the CPU, Expansion Unit, and Remote Slave since they differ. Devices which fall into the “Other” category (Row D)
are devices such as the Base and the Handheld programmer, which also have power requirements, but do not plug directly into the base.
3. Add the current used by the system devices (columns 3 and 4) starting with Slot 0 and put the total in the row labeled “maximum current required” (Row E).
4. Subtract the row labeled “Maximum current required” (Row E), from the row labeled “Current Supplied” (Row B). Place the difference in
the row labeled “Remaining Current Available” (Row F).
5. If “Maximum Current Required” is greater than “Current Supplied” in either column 3 or 4, the power budget will be exceeded. It will be
unsafe to use this configuration and you will need to restructure your I/O configuration. Note the auxiliary 24 VDC power supply does not
need to supply all the external power. If you need more than the 400mA supplied, you can add an external 24VDC power supply. This will
help keep you within your power budget for external power.
