Does StepperOnline Offer Stepper Drives Supporting Modbus TCP?

Among the stepper drives currently sold by STEPPERONLINE, the following models support the Modbus protocol:

• T Series: DM556RS, DM882RS, CL57RS, CL86RS
• Y Series: DM420PR, DM556PR, DM860PR, CL57PR

These eight drives can all be controlled via Modbus RS485 communication. However, the specific Modbus protocol used is uniformly Modbus RTU.

If you require the use of the Modbus TCP protocol instead of RTU, we regret to inform you that we currently have no related development plans. We recommend using an Ethernet smart gateway to convert Modbus RTU to Modbus TCP, which is a common and practical solution in the industry.
