Device which stored communication status

■

MODCOM Ch S1 S2 S3

(1) Example program

•

Designate slave station No. , function code,.address, No. of reading

•

When input condition(M0020) turns on, MODBUS communication starts.

•

Receiving data are stored D1000, and communication status is stored to M100

•

When operates as slave, MASTER-K120S responses to master station without commands. And When operates as master,

MASTER-K120S sends data in S1 with MODBUS protocol at rising edges of execution condition.
