MELSECA: Driver does not use maximum block size for read and write requests

Summary

The MELSECA driver does not use an optimized block size for reading and (block)writing variables in a consecutive address range.

Description

The MELSECA driver does not use an optimized block size for reading and (block)writing variables in a consecutive address range.

Solution

When the new driver configuration option "Optimized reading and writing" is enabled the driver uses a block size of up to 960 words. When disabled the driver behaves as before and uses a block size of up to 64 words.

This option is available only when using Mitsubishi Q series PLCs with the 3E binary format.
