ModScan
ModScan is for use in development or maintenance of multi-vendor systems utilizing the popular PLC communications protocol as developed by Gould Modicon. It allows the PC to operate as a MODBUS master device, polling a connected slave for data. The user may select a range of data to display using standard message types 01-04. Data may also be written to the device using single point write commands, (05 & 06), or multi-point writes, (15 & 16). This is one of those programs that you don't need very often, but when you do, it will more than pay for itself the very first time you use it. This Windows application will allow effective testing of MODBUS Slave devices in either ASCII or RTU modes of operation.
