Learn, test, and deploy Modbus—fast. Modbus Monitor Advanced is a complete toolkit that runs as Client (Master) and Server (Slave) with powerful write tools, conversions, logging, and cloud integrations. Use it to bring up PLCs, meters, VFDs, sensors, HMIs, and gateways in the lab or in the field.What you can do
• Master & Slave in one app: Modbus Client (Master), Modbus Server (Slave), and Modbus TCP Sensor Server
• Eight protocols: Modbus TCP, Enron/Daniels TCP, RTU over TCP/UDP, UDP, TCP Slave/Server, Modbus RTU, Modbus ASCII
• Four interfaces: Bluetooth SPP & BLE, Ethernet/Wi-Fi (TCP/UDP), USB-OTG serial (RS-232/485)
• Define full maps: Simple 6-digit addressing (4x/3x/1x/0x) for quick reads/writes
• Write tools for real-world work: One-Click Write from Write Preset, swipe left = Write Value, swipe right = Menu
• Data conversions: Unsigned/Signed, Hex, Binary, Long/Double/Float, BCD, String, Unix Epoch Time, PLC scaling (bipolar/unipolar)
• Turn integers into text: Map coded values to human-readable status/messages
• Push data to cloud: MQTT, Google Sheets, ThingSpeak (configurable intervals)
• Import/Export: Import CSV configs; export data to CSV every second/minute/hour
• Pro tuning: Interval, inter-packet delay, link timeout, live RX/TX counters
Sensor Server:
Use your phone/tablet as a Modbus TCP device exposing on-board sensors—handy for demos, training, and quick remote monitoring.

Not bad, certainly is the only app of this type. Seems the memory registers are off by one value. This also seems to cause a secondary bug where the offset .01 doesn't work. Oddly enough though .001 and 1 are fine values.

Very nice app with lots of features and documentation. However, for my purpose it didn't give what I was hoping. simple logging to local is not available, I expected Modbus visualization of values TBH. For my usage simple free serial terminal does the job well.
