Gentlemen, be careful with Profibus, there are different tastes of it. Especially the one designed for building automation will not very well suit our needs. But, certainly, this is highly professional technology, extremely noise proof even at long distances of several hundred meters. Peter Am

Re: [Emc-users] A lot of input/output. Cheap (Profibus)

I have used a lot of Profibus devices. I used to work for Siemens. Profibus is very robust if installed properly.DP is the norm for remote I/O. PA is designed for the process industry and not nearly as common. I always thought that a chip was needed for a DP master.I don't think a DP

[Emc-users] A lot of input/output. Cheap

Yo! I have this old injection moulder and the electric mayhem has degraded to a point were I need to either throw out the machine or rebuild. The machine is mechanically in good shape so I lean towards the latter. There are a billion of limit switches and the hydraulic system is managed by

Re: [Emc-users] A lot of input/output. Cheap

I do a lot of PLC programming and have used Automation Direct PLCs as I/O / Controllers attached to LinuxCNC via Modbus RTU. The Click series of PLCs are cheap and they have relay output cards. However if you have a lot of I/O and need auxilary control besides remote I/O to LinuxCNC, I think

Oh no, real time not needed. I would say there are maybe 40 switches right now and probably 20-25 hydro valves. With some better placement and logic I think probably half of the switches could be passed to the bin (you should see the electric wiring...). I can easily run the entire machine with an

Re: [Emc-users] A lot of input/output. Cheap

Hi, the big advantage of the mesa-boards is that they are well suited to drive relays and other kinds of devices. An Arduino or similar board only has TTL or CMOS IOs which need to get adapted to your actual IO voltages/currents. Parallel Ports also need some additional protection/drivers to

If you need help with ClassicLadder I'm fairly good at ladder logic. JT On 9/15/2015 6:02 AM, Sven Wesley wrote: > Oh no, real time not needed. I would say there are maybe 40 switches right > now and probably 20-25 hydro valves. With some better placement and logic I > think probably half of the
