Re: Re: [RTnet-users] TDMA: management time slot

[Andrea Forni]

Hi Jan, thank's for your suggestions....   I have two different situations:   1) Logical control: i have five or more nodes in my network which communicate in random mode (depend from machine's operations), in this situation I don't need a critical period for the cycle  (cycle: 5000us, it's acceptable).   2) Robot control: i have a control station (node A) and a station which calculate the robot's trajectory (node B), in this situation i would a comunication, between nodeA and nodeB, of 100/150us so that I don't miss the trajectory's points.    In second case I would understand if I can poll a node more than one time in a cycle of TDMA.    E.g. :   # Primary master     master:     ip 10.0.0.3     cycle 900     slot 0 150       slot 2 450     slot 3 750     # Slave A     slave:     ip 10.0.0.1     slot 0 0     slot 2 300     slot 3 600   In this mode, slave send a message to master every 300us. I would understan if this situation is feasible... I tried in the mode above (code in the old mail), but it don't work... I read the documentation of RTmac and I see a similar example, for this motif I ask you that....   Thank's for your patience...   Ciao      Andrea
