5.Features
The product features the CODESYS SoftPLC
CODESYS is a device-independent-PLC-programming system that is compliant with the IEC 61131-3 standard and supports all standard
programming languages such as ST or LD.
Compatible with Modbus TCP Master and Modbus RTU
Master *1
Modbus is a communication protocol widely adopted in the industrial sector.
Controlling and collecting data from devices with Modbus slave function can be conducted.
*1 When using the product with RS-422A/485 (multi-drop supportable), adding the CPSN-COM-1PD module is necessary.
