Basic Steps to Specify a LC700 System
1- A wide variety of SMAR parts for the LC-700 are available in the Modules and Accessories
chapter. If you have not yet taken a look at this section, please take a moment to review the parts
available in the LC700 family.
2 - Specify Communication Demands.
The LC700 CPU offers two options of communication, the first: serial EIA-232-C port and the
second: EIA-485 ports to remote connection in an industrial environment. For further details check
the communication’s section in the “LC700 Configuration Manual”. The ENET-710 module allows
connection of a LC700 system to an Ethernet network. The OPT700 module allows the connection
of a LC700 system to a fiber optical network.
3 - Check the available I/O modules
The LC700 system has different types of I/O modules. Check the chapter “Modules and
Accessories” and take note of the modules for use in the next project.
4 - Choose and check the power supply and quantity.
There are two available types of power supply modules:
- PS-AC-R (AC Power Supply Module)
- PS-DC-R (DC Power Supply Module).
It is important to calculate the power consumption of the modules in order to determine how many
power supplies will be required.
NOTE
CONF700 can calculate the power consumption for you! It is necessary to enter the modules in the
Hardware Page, and then simply click the Balance. To know more about this feature, see the
Getting Started section of the CONF700 manual.
5- Send a fax to quote on our competitive prices
For your convenience, CONF700 prepares the quote form and fills out your selected modules and
all accessories to accomplish the specified application..
See the topic, “Looking at the Balance” in the Getting Started section of the CONF700 manual.
NOTE
In case of use of long flat-cables, the IMB Vdc voltage should be measured to check the need of
adding a new power supply module. If the measured voltage is shorter than 4.95 V a new power
supply must be added. The Vdc voltage can be measured between the pins 16A and 16C from
any of the conectors in the last rack.
