If the total time of polling all devices is less than or equal to the "Polling interval" of any request in the queue.You cannot connect devices to different COM ports if you are going to combine the data received from these devices using the "Aggregation" module, as described above.When you should not connect devices to different COM ports:

#MODBUS RTU TO MODBUS TCP TRIAL#
Note: Available only in the Enterprise or trial version. You might need to do that if you read two registers located far from each other by using two different requests and then want to write them in one row to an Excel file, a database, or a text file.

In this case, the data communication will look like shown in Figure 9. The value in the "Split strings by data timeout" field must be greater than or equal to the timeout specified in the "Request timeout" field for the MODBUS request.įigure 8: Configuring the data display mode We recommend configuring the data display mode, as shown in Figure 8. How to make sure that the application sends requests and receives responses? It allows you to try all features! Plugins can be downloaded separately here
