Add MELSEC

 

The system configuration when using Mitsubishi Electric FA Connector allows for configuring a MELSEC device within ICONICS Workbench. See MELSEC System Configuration for more info.

 

Note: MELSEC devices can only be edited when disabled. Device configurations are validated when activated. When the device is activated, settings can not be changed until the device is disabled. See Activate and Disable.

 

To Add MELSEC

  1. In the Workbench, expand your project in the Project Explorer, and then expand the Data Connectivity node. Right-click the Mitsubishi Electric node and click on Add MELSEC, as shown below.

Marge Gap Details

Inconsecutive registers can be read in a batch in one communication between Mitsubishi Electric FA Connector and a MELSEC device by setting a value larger than the number of registers between tags to be monitored for "Merge gap".

 

Reading inconsecutive registers in a batch reduces the number of times of communication, which may increase the communication speed.

 

If the number of registers between tags exceeds a value set for "Merge gap", inconsecutive registers are read in multiple communications.

 

Example:

When monitoring tags for which inconsecutive registers are set:

  1. Registers set for a tag to be monitored: D20 to D50, D60 to D100, D200 to D300

  2. Registers  between tags to be monitored: D51 to D59 (9 points)

  3. Registers between tags to be monitored: D101 to D199 (99 points)

 

When setting '9' for "Merge gap"

D20 to D100 can be read in a batch in one communication because the number of registers for ‘b’ does not exceed a value set for "Merge gap". D60 to D100 and D200 to D300 cannot be read in a batch in one communication because the number of registers for ‘c’ exceeds a value set for "Merge gap". Therefore, D20 to D100 are read in a batch in one communication, and D200 to D300 in a next communication.

 

When setting '100' for "Merge gap"

D20 to D100 can be read in a batch in one communication because the number of registers for ‘b’ does not exceed a value set for "Merge gap". D60 to D300 can be read in a batch in one communication because the number of registers for ‘c’ does not exceed a value set for "Merge gap".  Therefore, D20 to D300 are read in a batch in one communication.

 

Precautions:

If setting a value larger than the number of registers between tags for "Merge gap" when the number of tags to be monitored is small, the communication speed will be decreased because registers not to be monitored are also read.

 

Depending on a protocol to be used, the size of registers that can be read in one communication may be small.

 

In this case, the communication speed is decreased because registers must be read in multiple communications.
