Configuration

1.1 Mitsubishi FX2N

Mitsubishi FX series are compact PLC. They connect to the computer throughserial link. As the FX protocol evolved through versions WebAccess has

di!!erent drivers to connect to the di!!erent Models.

The FX PLC contain potential connection ports. The programming port is the

only one that can communicate "ith the con!iguration so!t"are so you shouldconnect this one !irst. #t is a $%&'(( port but Mitsubishi usually sells a '(( to

(( converting cable "ith the PLC.

The t"o e)pansion boards can also be used to read the variable "ith

WebAccess* "e "ill e)plain their usage later in this document.

For FX(+ series please use the FX( driver in WebAccess. FX( and FX(C PLC

should use FX driver.

1.2 Module Settings

To con!igure the PLC you "ill have to install the ,X -eveloper so!t"are.

The !irst step is to upload the program currently on the PLC* this "ill alsoallo" you to check that the PLC is connected properly.

Choose the Comport and select 9.6Kbps speed.

go directly to the ne)t chapter.

#! you "ant to use an e)pansion board you have to set it up properly. The

e)pansion board is set through the PLC settings in ,X* the e)pansion board

t"o has to be set using ladder. #n both case you need to select the settingsdepending on your board /$%&'01 or $%&((2 and the %erial settings you"ant to use.

The protocol setting is !i)ed* you need to use 3-edicated Protocol4 "ith3Format '4.

For the other parameters the de!ault values are5 6 data bits* 7ven parity* stop bit* 89:: bps* no ;eader character* no Terminator character* Checksum

active.

For the e)pansion board ( you have to set three addresses using ladder5

2. WebAccess Configuration

2.1 ort

The Mitsubishi FX protocol uses a serial port. 7ven i! you use a serial port

server or a =%> to serial converter the apparent port in your computer /andthere!ore the port to select in WebAccess2 is a serial port.

2.1.1 Chec! the "ort nu#ber

#! you are using a comport emulator and you do not kno" the port numberthen open the 3%tart Menu4 and right click on 3Computer4 and select

3Manage4

#n the device manager section you can see the list o! C?M ports on your

computer and recogni@e the virtual port by its driver name

2.1.2 WebAccess Co#"ort age

?pen your WebAccess Con!iguration and select the %CA-A node you "ant toadd the device to. Then select 3Add a ne" Comport4

All the settings in this page must match the settings in all the modules

attached to the port. %o all the modules attached to the same comport musthave the same settings.

2.1.% Descri"tion

This is an optional !ield used !or user re!erence.

2.1.& 'aud (ate

For the Mitsubishi FX modules the typical baud rate is 89::.

This must match the baud rate con!igured in the module and the eventual $%&'01 to $%&(( converter.

2.1.) Data 'its

The packets can have 6 or 0 -ata >its. The typical setting !or Mitsubishi FX is7 bits.

2.1.7 Sto" 'its

The packets can have or ( %top >its. The typical setting !or Mitsubishi FX is

1 Stop bit.

2.1.* arit+

The Parity can be +one* ?dd* 7ven or -isabled. The typical setting !orMitsubishi FX isParity = Even.

2.1., Scan -i#e

This is the time in milliseconds to scan the -evices. This must match theability o! the device to respond. A typical scan rate is 1 per second.

#! the -evice cannot respond as !ast as the %CA+ Time entered* WebAccess

"ill scan at a slo"er rate.

2.1.1 -i#eout

With a second scan rate* a typical Time Out = 200 Milliseconds.

Timeout is the time "aited be!ore re&sending a communications packet that

did not have a reply.

Timeout speci!ies ho" long the so!t"are "aits !or a response to a data

reuest* speci!ically to "ait !or a reply !rom one packet. A recommendedvalue is one&!i!th the scan rate* longer i! the communication device is slo".

Combined "ith $etry count* Timeout also determines time to consider adevice or port as >A-. Timeout is the time to "ait since last communication

packet sent "ithout a reply. Time is in milliseconds. %lo" or poor ualitycommunications reuire longer timeout. The !aster the communications* the

shorter the timeout reuired. %horter timeouts result in !aster reconnectsa!ter communication !ailures.

2.1.11 (etr+ Count

A typical etry count = !.

+umber o! times to retry communications i! no reply is received !rom a

device. Combined "ith Timeout* also determines time to consider a device or

port as >A-.

This is the number o! times a!ter the !irst attempt has !ailed thatcommunication should be attempted be!ore indicating a !ailure. /#! $etry

count is * a total o! ' !ailed reuests have occurred be!ore tags are markedbad2. %peci!ically* this is ho" many times to send a single packet a!ter the

!ield device !ails to respond to the !irst packet. A!ter the retry count ise)ceeded* all the tags in the packet are marked "ith asterisks and the ne)t

packet o! reuests is sent. A reasonable value is to 1 times. A!ter thisnumber o! tries* the tags in this packet are marked as B!ail to respondB /i.e.

asterisks2 and are disabled. #n reality* increasing the number o! retries hides

!ailures on the part o! the !ield device to respond to a reuest. 7ssentially*increasing the retries gives the !ield device more chances to reply.

2.1.12 Auto (ecover -i#e

A typical Auto ecover Time = "0 Seconds.

Auto $ecover Time is the time to "ait be!ore attempting to re&establish

communications "ith a >A- device or port.

#! communications to the PLC is unusually slo" due to hard"are*

communications or net"ork issues* you might consider increasing this value.#! communications to the PLC or $T= !ails !reuently* you may "ant to

decrease this number in order to have WebAccess try to re&establishcommunications sooner.

#! communications to the PLC* $T= or device Fails /i.e. e)ceeds Timeout2WebAccess "ill "ait the Auto $ecover Time be!ore trying to re&establish

communications.

2.1.1$ /and Sha!e (-S

The typical setting !or Mitsubishi FX is #andS$a%ets = &o.
