I am actually working on a project where I m going to install a new manufacturing line fully automatic. I am going to use the ASI technology for the automation.
my request is : I need to bring the two asi wires in a drag chain (need to control a trolley).
Do they cable are ok for this utilisation. Won t I have any problem with ?

thanks for your help

]]> AS-i Power Fail tag:as-interface.co.uk,2009:index.php/forums/viewthread/.31 2009-06-15T05:37:13Z silva.foxx We have a conveyor system with a Siemens S7-317 2DP with 3 DP/AS-i Link gateways (6ES7194-5AA00-0XA0). At one of the gateways we are getting the “AS-i Power Fail” led flicker.

The AS-i bus PSU is an IFM AC1206 (http://www.ifm.com/ifmuk/web/dsfs!AC1206.html).

The AS-i network from this gateway daisy-chains out to approx 20 nodes of IFM AC2701 (http://www.ifm.com/ifmuk/web/dsfs!AC2701.html).

At node 3 we have an isolator auxillary input on I+ and I1 and an IFM OC5230 (http://www.ifm.com/ifmuk/web/dsfs!OC5230.html) on I+, I- and I3 via wires 1, 3 & 4 of the sensor. This sensor and cable have been renewed to rule them out.

The DP/AS-i Link indicates “Slave 3” flashes the AS-i Power Fail led. We have seen the IFM PSU power led flicker which led us to renew it with a new IFM AC1208 (http://www.ifm.com/ifmuk/web/dsfs!AC1208.html) which just seem to freeze the DP/AS-i Link. This happened when we tried another AC1208. We tried a known-to-be-working AC1206 from one of the working gateways on this system which worked. The PSU is set to 115vac. This supply is constant.

The AS-i node has been renewed along with the DP/AS-i Link. The cables have been checked out between nodes - SY cable not yellow AS-i cable - the inputs to this node 3 have been disconnected which stops the fault. The fault only occurs when we have the OC5230 connected. We tried another sensor but after an hour or so the fault re-emerged. Without this sensor connected to this AS-i node the network is fine yet the system has been running previously without a hitch. The voltage at the node is a constant 29.6vdc.

Can anyone point me to something I may be missing or have overlooked, please?

Thanks in advance.

]]> Removing a Node tag:as-interface.co.uk,2008:index.php/forums/viewthread/.15 2008-10-27T19:36:18Z asistudent How do I remove a node from an IFM AC1014?

I have taken the node off the ASi network but this has left me with an error on the controller. I now need to reconfigure to clear this error. We only have a hand held unit to program nodes and the pushbuttons and display built into the unit.

We do not have any PC based software do we need it?
