Issue when using PLC S7-1500 as OPC UA client to connect with OPC UA server having certificate
Danh Vo posted a topic in SiemensDear all, I'd like to get your support on the issue with OPC UA certificate. My OPC UA server has been built with Node.js. The PLC S7-1500 (firmware v2.9) acts as OPC UA client. It's working well without certificate but when I use certificate, there are 2 situations: 1. When connecting using "Online access" (as attachment) in the "OPCUA Communication >> Client interfaces", I can connect with certificate (after I export and copy the PLC's certificate to the trusted folder of the server). --> server is ok. 2. When coding and running with real PLC: can't connect, there is even no PLC's certificate on the rejected folder of the server and there is no any error, the Status of block "OPC UA Connect DB" is still 16#0000_0000. So, what I did with certificate in TIA Portal (V17) are: - Enable the Global security setting for certificate manager - Created (and tested) with both self-signed certificate and CA certificate for PLC - Added server's certificate to trusted list in "Certificate manager" of TIA Portal (also added to the "Certificate of the partner devices" in Device config) - In "OPCUA Communication >> Client interfaces", chose the Security Mode/Policy and PLC's certificate (already tried with and without this setting) In my point of view, the problem is that the PLC received the certificate but somehow it didn't read correctly or didn't compare with the certificate in the trusted list because if the PLC does this step, it should send its certificate to (the rejected folder of) server. Could anyone help me to solve this issue? Thank you in advance. [Update] 1.The PLC throw the error code 16#8016_0000 (BadCertificateHostNameInvalid/The HostName used to connect to a Server does not match a HostName in the Certificate - as I searched in google) but it's very quick so I could not see this behavior at the beginning. 2. I have tested with UA Expert, I can connect without any problem/warning. So, the high confidence that problem comes from PLC. ---------- Best regards, Danh Vo
Hello I use emulator to test and run my program . Currently ,I am not able to make communication between Rslinx and (RSLOGIC 5000 & Emulator). I configure my drivers from RSLINX but it does not configure from RSLOGIC 5000. I am not sure anyone know how to solve the problem?
Allen Bradley 1747-UIC DH485 Issues
craigrichards posted a topic in Allen Bradley / Rockwell AutomationHi there, I am having issues connecting my computer to our SLC 5/02. We have a genuine Allen Bradley 1747-UIC USB to DH485 adaptor, I have read into it a fair bit and have tried many different things. I have removed pin 3 configurations from the ethernet (DH485) as advised previously.. I have tried many drivers to get it to work to no prevail. I cant even change the CPU over to a 5/03 as I cant guarantee the program we have a copy of is the exact one in the CPU, therefore I cant just change to a different unit and establish comms that way. Does anyone have a step by step guide to connecting the 1747-UIC to the PLC? Many youtube clips dont seem to work for me like they do in the videos. Thanks a lot in advance if you can help!
ktp700 basic with profibus dp +S71241 CPU+CM1243-5
Moorthy posted a topic in SiemensGentlemen, I'm new to Siemens and now working on a project for my client. I have a S7 1241 cpu, CM1243-5 com module, a KTP700 hmi prifibus dp. The hmi is connected to the CM1243-5 via profibus cable. My problem: I'm not able to detect the hmi. My plc is connected to my router and I'm able to get online with it. I've attached some diagrams..just in case. Appreciate any help. thanks, Moorthy.
Cannot Connect to CP1L-E
darknightshine posted a topic in CX-OneHi guys, I was programming my CP1L-E over ethernet with no issues at all. I did get an error when uploading my program regarding cycle time, so I went into PLC->Settings->Timings and changed both values to maximum (4000*10ms watch cycle time and 32000ms constant cycle time). Once I restarted the plc it just wouldn't connect. I've tried option cards CP1W-DAM01, CP1W-CIF41, CP1W-EIP21 and i just cannot get comms with the PLC. I can see the CP1W-EIP21 card on my computer, however,, in its own IP address. From what ive figured, the plc is getting stuck somewhere in its boot cycle as I am unable to ping it either. The POWER and RUN lights are both green, and the LNK/ACT light flashes when i connect an ethernet cable to the inbuilt ethernet port. Any help is appreciated, thank you! Any way to factory reset the whole plc or even just the settings? I've disconnected the battery for 30 minutes before plugging it back in aswell but that did not help me.
Panelview 1000 does not display correct input
Fourdigger posted a topic in Allen Bradley / Rockwell AutomationHello I would like to first let everyone know I am new to the world of troubleshooting or programming plc's . What we have is a SLC500 system that is connected to a Panelview 1000 HMI via the DH+ network. The issue we have is the panelview displays a gate that is suppose to be closed at as gate fault. When i connect to the plc the ladder rung shows that the gate is closed. To show various positions of the gate the programmer used N13:70 as gate opened and N13:71 as gate faulted and N13:72 as gate closed. When i checked the logic it showed the bit N13:72 as engaged or true if you will. This logic is in the ladder rung that is labeled PV Status which i take is the status the HMI reads so my question is why does it show GF when it should be reading GC. Ive searched all through the logic and it doesnt appear to be wrong here is the logic the best I can simulate it ladder 6 rung 53 instruction is XIC O:13.0/11 and OTE N13:76/0 (Gate Open ) and the branch is XIC I:5.0/11and OTE N13:76/1 (Gate Fault) next branch is XIC N13:3/11 and OTE N13:76/2 (Gate Closed which this section is green or highlighted or true which ever you like) when i looked at the input XIC N13:3/11 this is what I found is that this XIC is on ladder four rung10 and has the following XIC T4:154/DN and branchoff that is XIC I:5.0/11(gate opened)XIC I:6.0/11(gate closed) which these two inputs are false or not lighted the output is OTL N13:3/11 and it is true which makes the previous rung true showing the gate closed. So why is the panelview showing the wrong position. I even went as far as resetting the HMI and the PLC so if anyone has a helpful hint I would greatly appreciate it.

NJ501 MODBUS TCP/IP COMMUNICATION ISSUE
dipen_95 posted a topic in OmronI am trying to get the communication going between EZ3 EZAutomation Panel HMI and Omron NJ501-1300 PLC. I am currently using Modbus TCP/IP as a protocol. Has anybody figured out a way to do that? Or is there a better way to do this communication between HMI and PLC ? Right now I am using MTCP_Client_Connect function block to connect with HMI but it dont seem to be working. The IP address is correct along with Port no. I am still fuzzy about the Station address of NJ and the function code of the NJ for Modbus purposes. If anybody could help me out I would really appreciate it.
excelparts posted a topic in Allen Bradley / Rockwell AutomationIm having some trouble with a PLC and looking for a some help. Whats happening is output number 3 is stuck on. I thought maybe it was just the PLC. I pulled the program tried it on a new PLC with no luck. I checked for faults and the handheld shows no major faults. The output that is stuck on is for a door, its telling it that the door is open. Any help would be great.
1756-IRT8I TC Analog Input Module
Bob A. posted a topic in Allen Bradley / Rockwell AutomationI just commissioned a system utilizing 3 1756-IRT8I TC Analog Input Modules. It was soon discovered that there were sags in the order to 2 -10 % in the inputs across all channels. These sags occurred in all three modules but at different times but were occurring more or less on ~4-6 hour intervals. There are two CJC inputs (Cold Junction Compensation) and it was discovered that one CJC value also sagged while the other one remained constant through the sags. Tech Support had no information about the issue, but eventually found that there was a thus far unannounced firmware update, that was made available. The problem modules all had FW Version 1.013 and the Update Version as of Mid Oct, 2015 is Version 1.014. Following the FW update, the sags are no longer being seen. Bob A.
