Hostlink "hello world"

[nikos 0]

Greetings and my first post here, Can someone instruct on a basic "hello world" type test of basic hostlink protocol communication, via a terminal application, something like retrieve the current time or a version or something? PC and plc work ok with the current CX based app, so connectivity is ok. I've been asked to re-do the application in a language we can support, e.g tcl/tk, so my first step is to test comms before continuing and not mess anything up on the current settings of the plc. I'm reading the hostlink pages now. PLC is CQM1H/CPU51. Pleas do not rec. opc solutions at this time as I'd like to verify this first basic step I will describe in more detail of what I would like to do in a future post. sincerely, and tia, nikos
