Additional Product Information
Modsak is a versatile Modbus diagnostic program. It will be of interest to device manufacturers, software developers, system integrators and field service engineers. Modsak can be used to test or simulate almost any device or system that uses the Modbus protocol: slave devices, PLC's, HMI's, MMI's, DCS's, RTU's, SCADA systems, bridges, gateways, etc.
If you are a device manufacturer, you can connect Modsak to the device you are developing to test its handling of the Modbus protocol and also its general operation. Software developers can use Modsak to simulate the environment (Modbus masters, slaves and gateways) in which their software has to operate. System integrators can plug Modsak into a system to temporarily replace Modbus components they don't yet have; or when components refuse to talk to each other Modsak can be used to try out different configuration settings. Modsak running on a portable computer will be a valuable tool for field service engineers, enabling them to monitor the communications between system components, or to send their own requests to the Modbus slaves in the system.
Modsak operates in one of four modes:
Manual master mode, where the user can send individual requests to a slave.
Automatic master mode, where the program continually polls (sends read and write requests to) a slave.
Slave mode, where it simulates a Modbus device (but without ModSlaveSim's programmability).
Monitor mode, where it relays messages between a master and a slave. This mode can be used to simulate a gateway or bridge, or as a form of protocol analyzer.
Modsak also supports: serial (RTU and ASCII) and network (TCP) interfaces; overlaid addresses for coils, discrete inputs, input registers and holding registers; all known extensions of the Modbus protocol for transferring floating-point numbers and 32-bit integers.
A free download of the full version of the program is available for evaluation from Wingpath's web site.
