Consider other models selected after considering the above four properties,
but also practical considerations based on the engineering applications of a
number of other factors, these factors include: Cost performance is no doubt
that the high-performance models will inevitably require a higher price.
Considered to meet the required performance, but also the investment of the
project to determine the models. Wuding loved her so much so that he granted her
so many bronze sculpture . Response-based Concept of the bronze sculpture
Speed of response-based digital control engineering applications, the
response speed of the programmable controller can meet the actual needs, and do
not have to be given special consideration. The analog control system,
especially with more closed-loop control system, you must consider the response
speed of the programmable controller. Different control objects have different
requirements for response speed, according to the actual need to select the
programmable controller. I / O points of the margin in any case, I / O points in
the system hardware design to allow sufficient as a backup. This is mainly based
on two considerations: First, the system design changes. The bronze sculpture
of Fu Hao is known to the world again. If you do not allow sufficient margin,
the system equipment adjustments, control functions increase, we should throw
out all the original design of a good system, resulting in unnecessary losses;
is given in the manual I / O points are the parameters obtained in the ideal
case, once operating at full capacity, it is necessary to affect the speed and
reliability of the overall system response, adverse impact to the system. In
order to ensure the normal operation of the designed control system, system
hardware design should be left according to the actual I / O points 20 to 30
percent margin. Living bronze sculpture Helps the Promotion of the Real Estate
Automatically change the model of the programmable controller bronze knife
device and then on the subject to choose. 3.3.1 programmable controller models
to select the general principles. The ability of the CPU power of the CPU is the
most important performance indicators of the programmable controller, the first
thing to consider is also the model selection problem. The programmable
controller of the CPU capacity. All sorts of bronze sculpture in the tomb of Fu
Hao, consisting of the shellfish, conch, etc. await us to do the search in many
ways and from multi-angle.
