Hello at All,

Has anybody been able to communicate from a CPU 315 2 DP S7 with a device via RS 485 with protocol ModBus RTU? To read or to write on this device's analogical and digital internal variables, which communication modules and which software are necessary to include on the side of S7? Do not hesitate to contact me at autcon20ATyahooDOTcomDOTar

Thanks in advance.
