A quick write-up article that could be used to facilitate implementations with regards to the following:
- ModbusTCP communication-based data transfer (method1)
- Real values scanning
The Method Procedure
The FX5 (GX Works3) settings
First, we need to ensure the correct device address registers and data types are being specified in the PLC.
Note that, since the information being scanned to adroit, requires device address registers in order to accommodate the scanning process, it is important to note that these variables declarations of global label type (as supposed to local label tape)
In addition, since a Real agent tag is to be scanned in Adroit, a Float (in this case single-precision) is to be used as the device data type in GX Works3.
The Adroit SCADA (Adroit Configuration Setup) settings:
Now the Adroit SCADA configuration setup is to be completed.
In this case run the Classic Adroit Setup (psexe.exe)
Create and configure a Modbus Ethernet Driver instance device – and configure accordingly:
Note – The key here is to turn swap floating-point word order – ON
Next scan the device in Adroit. (You can also verify your settings here – if required.)
From there – Real value should display in Adroit:
You can verify this in the Agent Configurator
From there this value can be used as required in Adroit UI.
The following Procedure video demonstrates the above concept, and also shows the settings used:
