Omron K7DD User Manual page 67

The data length and stop bits of the communications protocol Modbus RTU for the K7DD are fixed internally.
• Data Length: Always 8 bits
• Stop Bits:
Make sure that both the K7DD and the communications converter have the same RS-485 (Modbus RTU)
communications settings (baud rate, data length, stop bits, and parity).
Some communications converter models may require a driver to be installed. Install the driver properly, following the
instruction manual of the communications converter.
Use a commercially available product for the communications converter. OMRON performed an evaluation test on the
MGateMB3170 manufactured by MOXA.
The number of simultaneous connections of K7DDs using the Support Tool depends on the performance of the
computer.
OMRON have verified the operation of the system with five simultaneous connections.
