Software 4.4.2 Summary of commands The purpose of commands is to “operate” with the ope- rands (see "4.2 Operand ranges"). Eco Control 667E provides a large number of commands. They are listed and described in the tables starting on the next page. Memory requirements of commands Normally, the user program is stored twice in the user pro- gram memory: Ш as machine code which is read by the processor; Ш as intermediate code which is used for transfer actions between PC and PLC in accordance with the KUBES proto- col. Storing the intermediate code can be disabled by the relevant instruction in the user program ( а 3.10.2.1). The “No.
of bytes” table columns list the memory require- ments for both cases. 50
