Page 14

More Flexible Programming

The Greatest Program Diversity in the industry. A programming environment has been created that is highly readable and can flexibly support changes in specifications, to enable efficient design and program entry with few mistakes.

Highly Readable Programming

Programs are easy to see and easy to understand.

Bit Addresses can be used in the DM Area and EM Area.

 

NEW

DM and EM Area bits could not be specified with the previous SYSMAC PLCs, but they can with the CJ2 CPU Units.

Examples

D100.05: Bit 05 of D100

E0_100.05: Bit 03 of E0_100

BCD and Binary Timer Instructions can be used Together.

NEW

With the CJ1 CPU Units, it was necessary to select in the initial setup of the CPU Unit whether BCD or binary was to be used as the data format for timer instructions. With the CJ2 CPU Units, BCD or binary can be selected individually for each instruction by setting the data format of the timer set value.

The BCD TIM and binary TIMX instructions can be used together.

Array Variables make Data Specification Easier to Understand.

By using array variables, any data in a string of data can be expressed using a subscript, making programming easy to understand. Array variables can also be used for data stacks and function block I/O variables. Because they can be set for network symbols, the exchange of multiple data items with external devices can be easily programmed. (Usable languages: Ladder, ST, SFC).

Array Variable: ABC

 

Ladder language:
