1.Mitsubishi Q Configuration

1.1Mitsubishi Q PLC

Mitsubishi Q Series PLC are modular type PLC with Ethernet port and other types of connectors depending on the modules.

The MitsuQ driver will connect and read data directly from the PLC using the Ethernet port. The driver is listed in the TCPIP drivers.

1.2Module Settings

To make sure the PLC is connected properly to your computer and change the settings you need to install the Mitsubishi GX software.

In GX Developer create a new project and select Q type CPU.

Then setup the network parameters to test the connection

For the PC select “Ethernet board” and set the network to 1 (or another number if your PLC doesn’t have the default settings) and choose a Station number different from 0.

For the PLC select “Ethernet module” and type the IP address of your PLC.

Set “Other station” to “Single network” and “Network route” to “Ethernet”. You can now test the connection and validate the settings.

If the PLC has not been set you should define the different modules now in the software.

If the module has already been configured you can upload the settings.

We should now configure the PLC network settings so that WebAccess Can read data. Enter the “Network Parameters”

You can change the IP in the operational settings

Then go to “Open settings” to set the transaction options. Depending on the software version the pairing option will be named “No Pair” or “Disabled”. Please note the port number. The default port should be 5001 which in Hexa becomes 1389 (the port number is in Hexa in the settings page).

Now download the updated settings.

2.WebAccess Configuration


The MitsuQ protocol uses a TCPIP port. Unlike Serial Ports multiple connections (and therefore multiple WebAccess TCPIP ports) can be opened on the same physical IP port.

2.1.1Check the port number

For TCPIP ports the port number does not impact the driver. It is used to recognize the port inside WebAccess. You can choose any number bellow 64 but you should make sure that the port number does not correspond to a serial port on your computer (As the port number for serial connections must match the comport number in your computer).

2.1.2WebAccess Comport Page

Open your WebAccess Configuration and select the SCADA node you want to add the device to. Then select “Add a new Comport”

All the settings in this page must match the settings in all the modules attached to the port. So all the modules attached to the same comport must have the same settings.

2.1.3Comport Number

Choose any available comport number


This is an optional field used for user reference.

2.1.5Scan Time

This is the time in milliseconds to scan the Devices. This must match the ability of the device to respond. A typical scan rate is 1 per second.

If the Device cannot respond as fast as the SCAN Time entered, WebAccess will scan at a slower rate.


With a 1 second scan rate, a typical Time Out = 200 Milliseconds.

Timeout is the time waited before re-sending a communications packet that did not have a reply.

Timeout specifies how long the software waits for a response to a data request, specifically to wait for a reply from one packet. A recommended value is one-fifth the scan rate, longer if the communication device is slow.

Combined with Retry count, Timeout also determines time to consider a device or port as BAD. Timeout is the time to wait since last communication packet sent without a reply. Time is in milliseconds. Slow or poor quality communications require longer timeout. The faster the communications, the shorter the timeout required. Shorter timeouts result in faster reconnects after communication failures.

2.1.7Retry Count

A typical Retry count = 3.

Number of times to retry communications if no reply is received from a device. Combined with Timeout, also determines time to consider a device or port as BAD.

This is the number of times after the first attempt has failed that communication should be attempted before indicating a failure. (If Retry count is 3, a total of 4 failed requests have occurred before tags are marked bad). Specifically, this is how many times to send a single packet after the field device fails to respond to the first packet. After the retry count is exceeded, all the tags in the packet are marked with asterisks and the next packet of requests is sent. A reasonable value is 3 to 5 times. After this number of tries, the tags in this packet are marked as "fail to respond" (i.e. asterisks) and are disabled. In reality, increasing the number of retries hides failures on the part of the field device to respond to a request. Essentially, increasing the retries gives the field device more chances to reply.

2.1.8Auto Recover Time

A typical Auto Recover Time = 60 Seconds.

Auto Recover Time is the time to wait before attempting to re-establish communications with a BAD device or port.

If communications to the PLC is unusually slow due to hardware, communications or network issues, you might consider increasing this value. If communications to the PLC or RTU fails frequently, you may want to decrease this number in order to have WebAccess try to re-establish communications sooner.

If communications to the PLC, RTU or device Fails (i.e. exceeds Timeout) WebAccess will wait the Auto Recover Time before trying to re-establish communications.

2.1.9Backup Port

The Backup Port has not been tested for Adam 6K


Then Go to the port page and select “Add a new device”. Select the ADAM6K device Type.

2.2.1Unit Number

The Unit number is not important for TCPIP communication as it is replaced by the IP Address. Just select any available unit number.

2.2.2Port Number

The port number should match the one set previously so if you entered 1389 in the PLC you should type 5001 here.

2.2.3Use UDP

As we set a TCP type transaction set “Use UDP” to 0. It is also possible to use an UDP transaction but the settings are different.

2.2.4Network No.

The network number in WebAccess should match the one in the PLC. The default network number is 1.

2.2.5PC No.

The PC station number should be set to 255.

2.2.6Destination IO#

The destination IO address should be set to 1023 if it was not changed in the PLC.


There are no Blocks defined for MitsuQ driver but users can define their own blocks if necessary.


If you do not use all the channels in the device and you want to reduce your tag count you can add the parameters one by one using “Add tag”.


The parameter gives the type of tag you want to import. Try to select a parameter as close to the tag type as possible because it will fill the other option with the default parameters.

In MitsuQ all the available types have been put to the parameter list so by choosing the correct one all the other fields are set automatically. And the address template is given


The address is composed of letters giving the data type followed by the position in the memory containing that data type.

2.4.3Scaling Type

If the data sent by the module is not in a human readable unit you can use the scaling to change the unit and display a more convenient unit in the node. In most cases a linear scaling type will be sufficient.

2.5Supported Block List

There are no predefined blocks in the MitsuQ driver.
