Mitsubishi FX Serial Driver

The HMI operator panels can be connected to Mitsubishi FX PLC as the network master using this communication driver. The protocol has been designed to connect to the programming port of the PLC. Please note that changes in the communication protocol specifications or PLC hardware may have occurred since this documentation was created. Some changes may eventually affect the functionality of this communication driver. Always test and verify the functionality of your application. To fully support changes in PLC hardware and communication protocols, communication drivers are continuously updated. Always ensure that the latest version of communication driver is used in your application.

Protocol Editor Settings

Add [+] a driver in the Protocol editor and select the protocol called “Mitsubishi FX SER” from the list of available protocols.

Figure 1

PLC Models The list allows selecting the PLC model you are going to connect to.

The selection will influence the data range offset per each data type according to the specific PLC memory resources.

Comm… Gives access to the serial port configuration parameters as shown in the figure below.

Tag Editor Settings

Into Tag editor select the protocol “Mitsubishi FX ETH” from the list of defined protocols and add a tag using [+] button. Tag settings can be defined using the following dialog:

Figure 3

Resources Area of PLC where tag is located

Offset Offset address where tag is located.

SubIndex This allows resource offset selection within the register.

Type Data Type Memory Space Limits

boolean 1 bit data 0 ... 1

byte 8-bit data -128 ... 127

short 16-bit data -32768 ... 32767

int 32-bit data -2.1e9 ... 2.1e9

unsignedByte 8-bit data 0 ... 255

unsignedInt 32-bit data 0 ... 4.2e9

float IEEE single-precision 32-bit floating point type

1.17e-38 ... 3.40e38

string Refer to “String data type chapter”

NOTE: to define arrays, select one of Data Type format followed

by square brackets like “byte[]”, “short[]”…

Arraysize When configuring array or string tags, this option define the amount of

array elements or characters of the string.

Communication Status

The current communication status can be displayed using the dedicated system variables. Please refer to the User Manual for further information about available system variables and their use. The codes supported for this communication driver are:

Error Notes

NAK Returned in case the controller replies with a not acknowledge

Timeout Returned when a request is not replied within the specified timeout period; ensure the controller is connected and properly configured to get network access

Line Error Returned when an error on the communication parameter setup is detected (parity, baud rate, data bits, stop bits); ensure the communication parameter settings of the controller is compatible with panel communication setup

Invalid response The panel did receive from the controller a response, but its format or its contents is not as expected; ensure the data programmed in the project are consistent with the controller resources

General Error Error cannot be identified; should never be reported; contact technical support
