Display Formats
Input Status and Coil Status values are represented within a ModSim32 document as either 1 or 0. Register
values may be displayed in binary, decimal, hexadecimal, or floating-point notation. Floating-point
representation uses the contents of two consequtive 16-bit registers to assemble one 32-bit IEEE floating-
point value. ModSim32 can store a floating point value withe the most-significant 16-bits of data in the
low-order register address or the high-order register address.
Using the mouse to double-click on a displayed value will present a dialog box which allows you to edit the
contents of the data point. This dialog box also provides the configuration mechanism which allows
ModSim to automatically change a data point’s value based on a clock tick. Register contents may be
configured to increment, decrement or generate a random number between two specified limits.
Connections
Menu commands are available which allow you to define the characteristics of a serial connection to your
modbus network. ModSim32 supports physical baud rates up to 19.2K and may be used to simulate data
using either the RTU or ASCII transmission modes. ModSim32 supports multiple simultaneous
connections, and each document is accessible to multiple connections. ModSim32 may also be used to
simulate a modbus/TCP network server by selecting the appropriate command under the Connect menu.
