C200H-ASC[][] ASCII Units

Easily Perform ASCII Data Communications

• Perform ASCII communications with a wide range of external devices.

• The C200H-ASC11/ASC21/ASC31 function as special processing units with BASIC programming.

• Large-capacity user memory: 200 Kbytes

• Model available with RS422A/485 port.

• Various forms of data exchanges with CPU Unit: Select the best method for the read/write trigger and timing.

• High-speed data exchanges possible with shared memory (not dependant on I/O refresh).

• A wide range of interrupt processes: Interrupts fro CPU to ASCII Unit,  communications interrupt, key interrupts, timer interrupts, error interrupts, etc.

• Easy control of transmission control signals.

• Calculation instructions for error check codes.

• Many BASIC debugging functions (break points, 1-step execution, execution stop monitoring, etc.)

• Error log supported with up to 30 error records.

Functions

The ASCII Units support BASIC language programming and RS-232C and RS422A/485 serial communications. BASIC programming enables ASCII communications with essential any external device. It can also be used as a special processing unit to aid the CPU Unit without using external communications.

The C200H-ASC21/ASC21/ASC31 provided shared memory with the CPU Unit, and both the ASCII Unit and the CPU Unit can access the shared memory asynchronously, providing for high-speed data exchanges between the two Units without using interrupts.
