Doeyjohnny posted a topic in SiemensHello everyone, Are there any alternatives to WinCC at the moment that can handle using optimized blocks. In most other SCADA software, while importing tags, the option to optimize blocks should not be selected as they cannot import in this format. Ignition by Inductive Automation has a driver that can be purchased to solve this problem. I wanted to know if there are some other solutions to this issue. Thanks!
AB CompactLogix L32E Connections
NV_PLC posted a topic in Allen Bradley / Rockwell AutomationHi Everybody, I would like to get the Connections from an AB CompactLogix L32 with CIP. I can see these connections on the web interface. According to the CIP Vol1 v3.3 documentation I have created a reqest in java which requests the first instace of the Connection Manager Object with Get_Connection_Data service. I captured the sent and the received packets with wireshark. I would like to ask the following: 1.) Is this the correct way to request the connections from the PLC with CIP? 2.) The response says that "Service not supported", is it possible that the PLC does not support this service or there is problem with the request? 3.) Is there any other way to get the connections (I/O and Message) from the PLC with a CIP reqest? Thanks for the answers in advance.
Limiting on-line connections to a S7-1500 PLC
ErikSN posted a topic in SiemensHi, I was wondering if there is a way to limit the number of allowed on-line connections at a time to a PLC? Like can you somehow set in the PLC parameters that only 1 'connection' can be on-line in the device at a time? Thanks Edit: I'm referring to connections from the TIA portal - not HMI / ethernet connections and so forth
Updating PanelView C600 Clock from Micro850
bainsteven posted a topic in Allen Bradley / Rockwell AutomationHiya Guys, New here (first post!) - and I'm fairly new to Connected Components Workbench, so apologies for the mammoth post! I am currently developing a System using one Micro850 PLC and one PanelView C600 HMI. I am able to update the current HMI time by sending Unsigned-Integers to Global Connection Tags: System Clock – Hour ($SysClockHour);System Clock – Minute ($SysClockMinute);System Clock – Second ($SysClockSecond);However, if using the same “update time” more than once, this method does not work as the HMI is looking for a “change” in a Tag before an update occurs (Tag-specific). For example, we require to be able to receive a “synchronisation signal” on a digital-input on the PLC each day at 15:00:00. This will only work once as, even though the HMI’s current time updates every second, I will still be sending the values “15”, “0”, and “0” to the above Tags (which will therefore not force an update – as they haven’t changed). I cannot reset these Tags without updating the current Time – as any number “out of range” causes an error (incidentally the errors are shown on the HMI to occur on Tags “SysClockSecondTimed”, “SysClockMinuteTimed”, and “SysClockHour” – note the omission of the word “Timed” on the Hours error…). There appears to be no reference to these “Timed” Tags anywhere in CCW, and I have no idea why the “Hour” update errors on a different (the correct?!) Tag. It’s a pretty confusing problem and difficult to explain… it took me a while to get my head around it – and I can see what the code is doing! J I've looked for documentation on how these Global Connection Tags work, but I can't find anything. Everything I (think I) know so far is from extensive testing... so if anyone knows of any documentation, or has any suggestions as to how I can achieve the required result - that would be massively helpful! Thanks for taking the time to read all this! Cheers, Steve.
