I am currently using a BACnet gateway (FS-QS-1510) to connect to an M340 controller (P342020) via an Ethernet cable. I would like to configure the PLC as a Modbus TCP server to allow the gateway to retrieve data from it. Can you provide step-by-step instructions on how to accomplish this task? Additionally, please recommend any alternative methods for efficiently sharing data with the gateway.
The CPU functions as a Modbus TCP server by default, requiring no programming to enable this feature. Simply configure the IP, subnet, and gateway settings on the port to start serving Modbus TCP communications.
I am experiencing difficulty with reading data in Unity Pro. Even though I have checked the gateway module settings for data transfer and reception, I am still unable to access the information. I have attempted to map the data to an array of real values using %MW addresses. Is there any additional step I need to take in Unity Pro to successfully read the data?
In order to program using a USB cable, the CPU must have the Ethernet network configured with a static IP address on the same subnet as the gateway. This is essential for successful programming and data transfer.
I exclusively use an Ethernet cable for my setup. The Bacnet gateway is linked to an Ethernet switch, which also connects to the PLC. I access this Ethernet switch for programming purposes.
Are you able to ping both the PLC and the gateway from your PC?
While I can't provide a step-by-step guide in this post, I can certainly point you in the right direction. Firstly, you'll need to understand how Modbus TCP/IP protocols work; there are numerous online resources for this. To set up your M340 as a Modbus TCP server, you'll need to configure it via the Unity Pro software - See Schneider Electric's tutorial on this (Unity Pro - How To Setup Modbus TCP). As for alternative ways to share data efficiently, you might consider Fieldbus or EtherCAT, depending on your current infrastructure and future expansion plans. Always remember, the choice largely varies based on the specific needs of your system and the amount of data you are dealing with.
