YOKOGAWA ALR121-S53 Serial Communication Modules Used With A SCS For Performing Modbus Communication

Product Details:

Additional Information:

Description:

By using the SCS’s Modbus slave communication function, the data in SCS can be set or referred to by the Modbus master which is as separate system from SCS via a serial communication module. Furthermore, the subsystem data such as from sequencers can be set or referred to via a serial communication module using SCS’s subsystem communication function.

The dual-redundant configuration of the network can be available by establishing an independent transmission path from the Modbus master for every two the serial communication modules mounted in the SCS. However, control/ stand-by switching function in between the dual-redundant serial communication modules mounted on adjacent slots is not supported.

The serial communication module communicates with subsystems at the specified intervals and stores the subsystem data in the communication modules’ I/O image. The subsystem communication function of SCS accesses the communication module asynchronously from them, and refers to or sets the I/O image.

The application logic of SCS reads data from the communication I/O data area when the communication input FB is executed, and writes the calculation data to the communication I/O data area when the communication output FB is executed.
