kringh Posted July 20 Report Share Posted July 20 Hi. I have connected Citect Scada through ip 10.20.52.21 port 502, and Remote Operator through ip 10.20.52.21 port 20256. Both these work fine at the same time. I would like to test Ignition Scada, but I dont want to diconnect the Citect until I get the Ignition fully up and running since the Citect is collecting historical data that I dont want to loose. When I diconnect the Remote Operator I can connect the Ignition Scada through 10.20.52.21 port 20256 and the Ignition confirms that it has connected. The tags updates fine when connected through 502 port, but when using the 20256 port the tags just shows error. Do anybody know if it is possible to connect two Scada sytem at the same time to Unitronics V570? Quote Link to comment Share on other sites More sharing options...

MVP 2022 Flex727 Posted July 20 MVP 2022 Report Share Posted July 20 You have 4 sockets available to connect multiple devices to your V570. On those 4 sockets you can mix and match a mix of any available protocol or combination of master & slave. I've connected multiple SCADA devices to V570s many times, though I usually use ports 502 & 503, that is totally up to your discretion. Be sure you initialize the sockets to the correct protocol and port numbers, and if you are using MODBUS, be sure you have a separate MODBUS configuration block for each. If you also want to use Remote Operator, you will need to assign a separate socket and port number as it won't work if the socket is configured for MODBUS.

Come on!!! , this is because for your SCADA you are using MODBUS TCP/IP and remote operator is the proprietary Unitronics protocol. 2 hours ago, kringh said: . Do anybody know if it is possible to connect two Scada sytem at the same time to Unitronics V570? The actual relevant question to your problem is: can you make changes in your PLC program? if you have the source code and you can make the chances you have 2 options: - Add another MODBUS protocol in other socket - Connect and disconnect sockets between servers (Modbus MASTER devices, that is most likely how your SCADA setup is), maybe use UDP instead of TCP for this Quote Link to comment Share on other sites More sharing options...
kringh Posted July 20 Author Report Share Posted July 20 Thank you for all help! I don't know how to program the PLC, and I was hoping there was some kind of default port connections. I understand now that this have to be configured in the PLC. I also tought that when I disconnected the Remote Operator from the PLC I could connect the Ignition to the same ip and port as R.O was using(20256). I am sorry if I am asking dumb questions. I will read the links provided. Thank you! Quote Link to comment Share on other sites More sharing options...
MVP 2022 Joe Tauser Posted July 20 MVP 2022 Report Share Posted July 20 Ports and protocols are fairly easy to define in the PLC; and as Flex mentions you can have four simultaneous conversations going on at the same time with a V570. Do you have the program? Joe T. Quote Link to comment Share on other sites More sharing options...
kringh Posted July 20 Author Report Share Posted July 20 I do have the program, but it is another guy that made the program, and I dont' know if he would like me to do post it on the open forum, and he is not reachable. Quote Link to comment Share on other sites More sharing options...

As you found, this will not work. When using MODBUS (typical for SCADA systems), the port must be configured to talk MODBUS. Since you were using that port to talk to Remote Operator, it was incapable of talking to the SCADA using MODBUS. All of this is easy to fix, but you must have access to the program and the bit of knowledge required. Quote Link to comment Share on other sites More sharing options...
