I'm working in the planning stages of a big project which will require data exchange over Ethernet between 8 off S7 plc's and 6 off Controllogix plc's. I've spoken to our normal hardware supplier tech support guy and he has advised me to use an Anybus gateway (www.anybus.com) to translate the different Bradley & Siemens Ethernet protocols.
I have done Ethernet communications before between Bradley plc's, S7 plc's and between S5 & S7 a while ago, but never between Bradley & an S7. The Bradley plc's are our responsibility and the S7's are from another equipment supplier on the same project.
We need to exchange a DINT in either direction between each Bradley plc and each S7 plc. I want to use the MSG instruction on the Bradley side of things and wondered in the naming of the DINT tag in my Bradley plc was important to make it easier to set things up from the S7 side? I'm assuming at this stage that the S7's will be using the AG SEND and AG RECEIVE functions and seem to recall that the TSAP settings had to be identical on both plc's for everything to work when using Ethernet comms with Siemens. Obviously I have no TSAP settings on my Bradley plc's.
Does anyone in here have any experience of setting up communications over Ethernet between an S7 and a Controllogix plc?
Any help or pointers would be greatly appreciated. I realise I've waffled on a bit but hopefully someone will get the drift of what I'm asking.
