1 Installation
This driver addendum is additional to the PLC-ANALYZER pro handbook and explains particularities and provides important information for the use of the following driver:
· MITSUBISHI MELSEC Q / L / A / FX - programming interface
This driver acquires PLC signals via programming interface of the PLC.
It is important, that you read through the driver addendum first, before you use a PLC driver.
Please pay attention to the WARNINGS that advise you on possible dangers when using PLCANALYZER pro.
!
Warning
Errors that may occur in the automated facility endangering humans or causing
large-scale material damage must be prevented by additional external precautions.
These precautions (e.g. independent limit monitors, mechanical interlocks) must
guarantee a safe operation even in the case of dangerous errors.
1.1 Installation of PLC driver
You can install the PLC driver when PLC-ANALYZER pro is running. Select PLC driver in the
menu Extras. In the window PLC driver click the button Add. If the desired driver is not in the
list, then you have to install a new driver by activation via the License-Key management (s. user
manual PLC-ANALYZER pro 5 - chapter 2-2 Installation).
With PLC-ANALYZER pro you can load the same or different PLC drivers more than once to
acquire data from different PLCs.
1.1.1 Installing additional hardware
If you have already connected your programming unit (or your PC) for programming under
Mitsubishi GX Developer with the automation device, then you normally must do nothing else.
Otherwise connect a free COM port (serial connection) of your programming unit (or PC) with
the programming interface of the automation device.
1.1.2 Installing additional software
Aside from the PLC-ANALYZER pro base module and PLC driver you must install the programming software Mitsubishi GX Developer.

1.2 Configuration of the PLC driver
After installing the driver select Properties. If various drivers are installed, the parameters of each
can be adjusted individually.
Fig. 1-1 Configuration of the PLC driver
First enter a meaningful Name. Choose under PLC whether you want to record signals from a
MELSEC Q-, A- or FX-control.
Under Port you select the COM port or the USB port of the PC, which is connected to the PLC.
Set whether the connection cable is attached to the C24-Module or directly to the CPU.
If you choose MELSEC Q or MELSEC A set the parameters in Baudrate, Databits, Stopbits
und Parity.
Set under PLC-Address the address of MELSEC Q resp. of the MELSEC A. The PLC address is
a 2-digit hexadecimal value. The default value is “FF”. It means the station itself. In a
MELSECNET or MELSECNET/B it is possible to interfere a slave by indication of a station no.
Note, if you choose a master-station you can interfere to all slaves, but from one slave-station
only to the Master and the slaves between.
Use Time stamp to decide whether a time stamp is to be entered in the signal file at each monitoring point or only when the signal changes. In the first case the signal file resulting is bigger
because time stamping is continuous even if the signal does not alter.
Scan interval lays down the interval between reading data from the PLC. For time insensitive
applications e.g. temperatures a generous probe interval can be chosen. The signal files resulting
are smaller.
Under Symbolism you can assign a symbol file to the loaded driver. This makes possible the use
of symbolic addresses during the address input (s. user manual PLC-ANALYZER pro 5 - chapter
Contents
1-3
4.1 Address selection). In addition to the absolute address the symbolic address and the comment
of the address will be displayed and saved in the project and in the signal file.
Click the button Connecting test to check whether the PLC-ANALYZER can establish a connection to the PLC with the adjusted parameters.

2 Data acquisition
2.1 PLC Models and CPU’s supported
The following models of the MELSEC Q series are supported by the driver:
Q02(H)CPU, Q06HCPU, Q12HCPU, Q25HCPU, Q02(H) A mode, Q06HCPU A mode,
Q12HCPU A mode, Q25HCPU A mode, Q2A(-S1)CPU, Q3A, Q4A, Q4AR
The following models of the MELSEC A series are supported by the driver:
A0J2HCPU, A1CPU, A1NCPU, A1SCPU, A2CPU(-S1), A2NCPU(-S1), A2ACPU(-S1),
A2CCPU, A3CPU, A3NCPU, A3ACPU, A3HCPU, A3MCPU, A3UCPU, A4UCPU
The following models of the MELSEC FX series are supported by the driver:
FX-x, FX0N-x, FX0-x
Other automation devices and CPUs from the MELSEC family are generally compatible with
PLC-ANALYZER pro, but have not been explicitly tested.

2.2.1 Number of simultaneously recordable addresses
You can monitor 512 addresses simultaneously with the Mitsubishi MELSEC driver. An address
means a word- or a bit address.
2.2.2 Use of name lists (symbols)
You can use variables created by Mitsubishi GX Developer as symbols in PLC-ANALYZER pro
(see user manual). Therefore you have to export the variables as CSV file. Select Export variables in the Extras menu to do this.

Data acquisition

The following captures describe the time behaviour and some particularities during the data acquisition.
2.3.1 Data transfer speed
The intervals between scan transfers from the MELSEC PLC to the computer are dependent on
the cycle time of the PLC and the baudrate.
For a scan interval of e.g. 20 ms and an equal cycle time of the CPU there is one scan for each
cycle. If the cycle time of the PLC is longer, the scan intervals synchronize with the PLC cycle.
For a shorter cycle time the computer does not obtain a scan for each cycle, resulting in a partial
loss of information. This loss can be made up by repeated measurement of the signals in question.
Note that bit values and word values use two separate calls. That’s why bit values and word values don’t descend from the same PLC cycle. The offset between both is max. one scan normally.
The following table shows some values of time behaviour during acquisition:

Data acquisition

The acquisition influences the cycle time of the controller. The more addresses will be recorded,
the more prolong the cycle time. This is normal and occurs in “Batch Monitor” with the programming software GX-Developer too.
