Test SCADA and IIoT applications without PLC or industrial devices
A Modbus device you can start on your own machine. Point your SCADA, HMI, historian or your own code at it and develop against realistic register data before any hardware arrives — or after it has gone back to the customer.
Windows. Free for engineers — no account, no licence key.
What it does
Modbus TCP and RTU
Serves both framings, so a client can be tested exactly as it will run in the field.
Configurable registers
Coils, discrete inputs, holding and input registers, with the data types and byte order your device really uses.
Simulated values
Fixed values, ramps and patterns, so an alarm, a trend or a deadband can be exercised without waiting for a process to move.
SCADA and HMI testing
Commission screens, tags and alarms against a device that behaves predictably.
Background reading
How to test Modbus without a PLC
Develop and commission against a simulated device when the hardware is unavailable, on order, or already installed at a customer site.
How to test a SCADA system without hardware
Commission screens, tags, alarms and trends against simulated devices, and know which classes of problem you still have to find on site.
Moving from testing to production?
When the device is understood and the data needs to go somewhere continuously, Edge Gateway turns the same tag map into a deployed runtime.
