DVP-ES3 Hardware Framework
4.1.1 DVP-ES3 Hardware Component
The DVP-ES3 series programmable logic controller is a small programmable logic control (PLC). The execution
speed and memory capacity are increased. Use of function blocks is also supported. In order to meet your
more advanced application requirements, the DVP-ES3 series programmable logic controllers provide more
flexible system extension frameworks. Under such system frameworks, you do not need to use several CPU
modules to control the system because there are too many I/O points or the equipment is too far away. This
retains system completeness, and you can be more efficient in developing projects.
The minimum framework requirement for the DVP-ES3 series system is only one CPU module.

The following lists the limits for setting up a common framework of the DVP-ES3 PLC system. Exceeding the
first two limits causes the PLC to send an error message.
Limit 1: The maximum number of digital I/O points is 256. The built-in digital I/O points of the CPU module are
included. If DI points are 200, you can have less than 56 DO points.
Limit 2: You can connect up to 8 modules (AD, DA, XA, PT, TC or PU) to the PLC.
Limit 3: The maximum power consumption of CPU module and extension module should be within the range of
what a CPU module or a power module can supply. Refer to section 4.5.4 for the maximum power
consumption of modules.
