D2-09BDC1-1 AUTOMATION DIRECT

The example on the right shows how 

to calculate the power budget for the 

Do-more PLC system. The examples 

are constructed around a single 9-slot 

base using the devices shown. It is 

recommended you construct a similar 

table for your Do-more PLC system. 

Follow the steps to the right to determine 

your power budget.

Module Placement and 

I/O Usage Tables

There are very few I/O module placement 

restrictions with the Do-more H2 Series 

PLC family. In general, any mix of analog 

and discrete module types can be used 

in any local or Ethernet remote base. 

However, specialty modules can’t be 

used in the Ethernet remote base except 

for the F2-08SIM. Reference the Module 

Placement Restrictions table to the right 

for the Do-more H2 Series PLC.

Analog I/O in the Ethernet remote 

bases

When using an analog module in an 

Ethernet remote base, the analog update 

time to the CPU will be asynchronous to 

the scan time. Critical analog I/O should 

be located in the local base.

I/O point usage

The table to the right indicates the 

number of I/O points consumed by each 

module. Use this information to ensure 

you stay within the maximum I/O count 

of the I/O system you have chosen.
