Question

Can I read/write data from/to one or more DL PLC? How about to a non DL device?

Answer

1. The DL06 can use port 2 as a master using Direct Net or Modbus RTU.

2. Port 2 supports RS232, and RS422, for both DirectNet and Modbus. RS485 (2-wire)can only be used with Modbus. If you use RS422 or RS485 you can communicate with a network of devices. All devices on the network need to support the protocol the master DL06 port 2 is configured for.

3. If connecting to third party devices, you will use the Modbus RTU protocol. When doing so you will need to convert Modbus addressing to DL octal addressing. To help with this task, we have a Modbus Conversion utility available on our technical support page. Modbus Conversion Utility

4. The DL06 supports two instructions, MRX and MWX, which allow you to address the Modbus addresses directly without the need to convert to octal addressing.

5. Chapter 4 of the D0-06USER-M manual covers the communications port and networking starting on page 7. Click here for Chapter 4 of DL06 User Manual.
