Behaviors

A behavior drives how a register or bit value changes over time (counter, sawtooth, noise and so on). Bindings are shared across all users, any change immediately applies to everyone. Slave 10 has no behaviors; its IR are computed (time zones and the Unix timestamp).

Presets

Quick setup for the form below: fills in the behavior and its parameters. Presets work for numeric areas hr/ir, «Reset» sets constant 0.

Current overrides

Bindings that differ from the default behaviors (HR/CL - constant 0, IR - counter and the generator showcase, DI - random bits and second-counter bits, top HR slots - demo generators).

Mini chart

The chart shows how the register value changed over the last minute. The Unit ID, Area and Address fields above pick the register to plot. New points appear on their own as soon as the value changes on the server.

The server is free and stays that way. We are raising money for a test bench with real instruments to run every ModbusToolkit build against.
