Maintenance function
*1 Since a boot project contains about 23KB of service information besides program, available memory size for user program is
about 1000KB instead of 1024KB (1MB).
*2 Gateway: Communication with EHV-CODESYS / HX-CODESYS
*3 ErherCAT master and Modbus-TCP master are supported by CPU ROM VER. 3.5.3.42 or newer version.
