Description: The first step to H0C8E sent to the D8120 in the definition of communications format,
this step in the FX Series PLC 485 must communicate, whether to control the inverter or with the
computer communications should be written in the second step is to identify the station number,
my 4-PLC are H0, H1, H2, H3. The third step is communication without response time, I set the
second, the general good can not go wrong as long as the system configuration.

Mitsubishi factory in accordance with instructions, 485BD can only do 50 meters of communication,
my plot of this system is used for surveillance, 50 meters is not enough. Although FX0N-485ADP can
do 500 meters, but I want to break what 485BD limit, so use a good quality two cable, one net, then
a pair of signal lines, successfully achieved a 120 m communication normal!

There are four residential buildings with necessary monitoring, control each building up a 40MR water
systems, prior to doing the old residential water supply systems, PLC control cabinet to control the past.

| --- 1 Building control room computer Century Star |
| --- 1 Building Electrical Control Room 1N 485BD total distance of about 10 meters |
|
| --- 2 Building Electrical Control Room 1N 485BD total distance of about 45 meters
| --- 3 Building, Room 1N 485BD electric control the total distance of about 80 meters |
| --- 4 Building, Room 1N 485BD electric control total of about 115 meters from the Main Control Room
computer software installed on Century Star, corresponds to each floor need to control all the points,
I am in main control room in can the four quarters of the water system into the ground to monitor and control.

This approach is a more economical approach.

Next project, there are seven high-rise, plans to use seven (FX2N-16MR FX0N-485ADP FX2N-16CCL)

In this way, you can do to control the trunk 485, 7 CC-LINK for the branch control network.

The seven storeys were required in the fifth layer, 10th floor, 15th floor, and the 20th floor and put on
32 points of hybrid modules AJ65SBTB1-32DT controlled central air-conditioning turned on, in fact only
two points into the first floor, three points out, there are surplus. (AJ65SBTB1-32DT remote I / O module,
16-point input, 16-point output)

20 House need to put in more of a AJ65SBT-62DA control two speed pump.
(AJ65SBT-62DA remote analog output, 2), just one of the highest AJ65SBTB1-32DT more than
two switches to control two pumps.

Sometimes, the factory of note also is not necessarily the truth.
For example if the net, with two high screen, you can break 485-BD 50-meter limit.
Do vary from time to time to use the network control high Q-PLC, with the economy, like FX series PLC can
achieve very good results.
Floor residential accommodation is relatively less demanding, and the environment as bad as the factory,
on the contrary if I was not in the factory on important occasions selection FX1N, although the official
said Mitsubishi FX1N have excellent stability, and proved in practice that Power volatile situation,
FX1S, FX1N power module damage probability is very great.

The adapter for FX-485ADP RS485 or the adapter for
FX0N-485ADP RS485 (both called 485ADP hereinafter)
is designed to link the data between PC and
computer by using 485PC-IF.
(1)Data exchange by request from computer
Specified data can be exchanged by sending a request command
from the computer to the PC. Except for
few functions (global function, on-demand function), the program
for data link is not needed at the PC side.
* Batch read / write of all devices (word unit, bit unit) of PC is
possible. By reading out the content of each
device of the PC, the operating state can be monitored, or the
data can be acquired and analyzed. Besides,
by writing data into each device, production control and
production direction can be effected.
* Remote run / stop of PC is possible. A stopped PC can
be started and stopped again from the computer,
and therefore the PCs are remote controlled.
* A batch instruction can be issued to all PCs. When one computer
and plural PCs are connected, a specific
device (special auxiliary relay M8126) can be turned on or off
from the computer to all PCs on the circuit.
This function is called the global function. This special
auxiliary relay M8126 is an exclusive device for
global function.
(2)Data exchange by request from PC
If transmission of emergency data from the PC to the computer
is necessary, the PC issues a send request
to interrupt in the computer. This function is called
on-demand function, and is enabled only when the
system is composed of one computer and one PC.
