AT Control System designed new libraries for Modbus RTU Master and Slave protocol.

New libraries for implementing Modbus RTU protocol are dedicated for NX70 and NX700 PLCs (CPU750 series central units).

This libraries are designed for implementing in FPWinPro software. They use COM port in CPU750 central units (NX70-CPU750, NX-CPU750A/B/C/D) as well as communication ports in SCU module (NX70-SCU, NX-SCU).

This library enables Modbus RTU Master and Slave. It is also possible to use this library in SCU modules mounted on Remote IO cassette, in Modbus RTU Master as well as Slave mode. The only limitation is the size of sent querry and received responces. The number of registers may not exceed 30 registers wrote and 28 registers read.

Modbus libraries are free and a user may download them from our server.
