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
Processor from Upload is different than controller
joesalmans posted a topic in Allen Bradley / Rockwell AutomationUploaded a program from a micrologix 1400, I added an integer data file. Went to download it, and the processor types were different. I suppose I am just going to change it to match what is on the machine, but why did this happen? The controller was password protected. so maybe it did not get the processor info for some reason. Even when online with the processor, it reads incorrect.
No voltage at outputs even when forced
Greenhorn posted a topic in Allen Bradley / Rockwell AutomationI am very green at this and learning online as I have purchased a brand new Micrologix 1400 1766L32BXBA. I am pulling my hair out as I cannot even power an LED or for that matter get any 24 volt reading from the outputs via program. I have even forced them on so shouldnt I be able to see something? I am connected via Ethernet ,Rslinx in concert with using Micro starter software (not lite) and the unit does not show any faults and is in the run mode. I can see the bits forced on the software and on the unit's LCD screen in I/O status. Is there a way to trouble shoot if the unit is bad or I am overlooking something incredibly simple. I do not have any floating inputs or outputs with the common from the power supply and the unit is properly grounded all nice and tidy on a din rail. Like I said I am very new at this so I am sorry if this is a bad question.

Mapping to a Single Element in an Array
dmturner posted a topic in Allen Bradley / Rockwell AutomationI have 23 Micrologix 1400s and I want to take the same register, N100:99, out of each one and put in a single array in a CompactLogix L18ER. From what I have tried, it only seems like I can only map a range of integers, N100:77-N100:100, to the array and not an individual register to a particular element. (For example, mapping N100:99 from machine 16 to Selected_Model) Can you map to individual elements in an array? If so, are there any instructions on how to do so? Thank you in advance for reading my post!
Micrologix 1100 Ethernet Message Connections
k0d3 posted a topic in Allen Bradley / Rockwell AutomationGood day everyone, First post here so hopefully I'm not violating community guidelines in anyway. I've got a system that has some 50 odd Micrologix 1100 and 1400 in use and I'm currently working on setting up an auto timesync for all of them using just 1 of the PLCs that will be my master time PLC. So far I've put together the logic for all the message instructions with the corresponding IP of the slave devices. I'm running. Into an issue with not being able to terminate/break the message connection on a PLC that I have already synced. Is this even possible to do on the ML1100. Once I get to 16-17 messages DN it starts to ER and will not complete any further messages. What I have is a message instruction ladder with a timed trigger to activate a MSG and write the RTC data then time down and connect and write to the next and so on. When it triggers the message instruction of one PLC it also fires an OTE to trigger the BK of the previous message instruction. However it doesn't seem to be actually cutting the message connection and holds it persistent until a power cycle/download event.

Citect Scada and Micrologix 1100
GustavoArg2021 posted a topic in Modicon / Telemecanique / Schneider ElectricHello everyone! I would like to connect a Micrologix 1100 with Citect 7.5 via ABMLXEIP (updated to latest version). I tried everything and it is still not working. The Citect and the PLC are on the same subnet and the ping works fine. All the configuration is done as the manual says (I attach the pictures). I have one NIC card and is connected to the PLC. The role is setted to “Server and Control Client”. The kernel has this error: [ERROR] [CORE] [0x07fc] [IOServer] [(GLOBAL)] [ErrorLog()][errlog.cpp] [266 ] Error: Channel offline, cannot talk CINIT 0015 PORT1_BOARD1 IODev_1100 Error_in_CMD-2 16 Generic 000021 Driver 00000020 (0x00000014) Any help would be much appreciated!

SLC 500 and SMC Ex260
Megoof posted a topic in Allen Bradley / Rockwell AutomationI'm trying to connect a SMC EX-260 to a Allen Bradley Micrologix 1400 PLC so I can run some valves with it. However, RsLogix 500 doesn't allow me to just setup a generic ethernet device like I would on RsLogix 5000. Is there a way I can communicate these devices together so I can use the SMC Valve system with my Micrologix?
Square Wave Problem With Micrologix
seabiscuit101 posted a topic in Allen Bradley / Rockwell AutomationHello all, this is my first post. I am using an AB Micrologix 1400 (1766-L32BXB Ser C FW 21). I was trying to generate a pulse train using the PTO instruction. I have modified PTOX funct. file. The ladder is just a simple XIO followed by PTO, (The Quick Start ladder from 1766-RM001). When I looked at the output waveform on my oscilloscope, I noticed that it wasn't a square wave. I decided to run it at several different frequencies to see how the wave form would change. At 10Hz i got a square wave. As I increased the frequency the falling edge became sloped and almost horizontal. Is this how the output should behave? The data sheet indicates a max frequency of 100kHz, but at frequencies over 150 Hz. The wave form looks like the output of SMPS.
Why does ML/1400 send a TCP [RST] ?
gazroo posted a topic in Allen Bradley / Rockwell AutomationHi all, I have my own driver to communicate with a MicroLogix 1400. Please refer to the attached screenshot from Wireshark. 10.10.21.10 is my driver's host, and 192.168.1.192 is the ML1400. The startup sequence to establish a connection & session with the PLC is correct I believe: - In the grey highlight, client requests a connection to .192 via SYN and this is ack'd - A session is registered, and forward open is successful - There's a lot of stuff in green simply because I've also got an HTTP browser session open to the PLC to monitor its session table - In between, spaced 8 seconds apart, are my two attempts to keep the connection alive by sending a List Identity request (as a ping, if you like). These are highlighted in pale blue. - However, 16.5 seconds from the start of the grey highlight, and 16.4 seconds after sequence=115 ack=99, the controller sends back a [RST, ACK] and a callback from my socket code tells me that the session has been dropped. The connection timeout for the PLC is configured as either 30 or 60 seconds, so I don't see how that's relevant here when the reset is happening only 17 seconds after it was established ? However, presumably the PLC doesn't see the application-level "List Identity" request as a valid means of keeping the connection alive. What is the correct mechanism to use that the PLC will accept as a keep-alive ?
How big is a sub-element ? (SLC/MicroLogix)
gazroo posted a topic in Allen Bradley / Rockwell AutomationHi there, As a software engineer, but a newbie to the Allen-Bradley world, sorry if this question doesn't make sense. I'm enhancing an existing driver by trying to add the ability to read/write structured and array data types - rather than just the elementary data types it supports right now. This following question is only in the context of SLC/500 & MicroLogix 1400. And I'm currently working on a Counter as a test case, but any solution obviously needs to take into account other structured (and array) data types. One of the requirements is that the user should be able to select a specific atomic item within a parent structure/array that they want to read/write. So, using the Counter as an example, they might want to define a field which holds just the value of the accumulator. I know that I can achieve this with a CIP command. I specify file type 87 for counter, file number as 5 (my test example happens to be the standard C5 data file of counters), and element is 0 (for the first counter in C5). Bit number is irrelevant so remains as zero. I ask CIP to return me 2 bytes of data (to hold just the accumulator word). Finally, I tell CIP that I want sub-element 2 (because the accumulator is Word 2 of the whole structure). Sure enough, the CIP response gives me exactly the 2-byte accumulator value I was expecting, nothing more, nothing less. Success. My question is this: I knew I had to specify the sub-element as 2; this happens to work for a Counter because of the way it is structured as 3 words. However, it implies that the value I specify for sub-element is ALWAYS measured in units of 16-bit words. Is this a universal truth (i.e. works for other structured types too ?), or does the size of a sub-element depend on other factors, such as the file type ? Thank you in anticipation.
GuyMiller posted a topic in Allen Bradley / Rockwell AutomationI thought only PLC5's had EEPROM, but I was told MicroLogix PLC's also have an EEPROM that need to be burned to... What are all the PLC's that have EEPROM and require an EEPROM burn to prevent the program from being wiped in a power cycle?
Micrologix 1400 Lookup Table over Ethernet/IP
cekann posted a topic in Allen Bradley / Rockwell AutomationMy project is to read an RFID tag (ascii) with a Micrologix 1400, send the string to a PC using Ethernet/IP, lookup and compare in an Excel spreadsheet, and send back data (probably an integer) for the plc to use to control direction. I have to scan and compare an RFID tag to a list of 1400 possible part numbers, at different locations (more than 1 plc). I want the several PLCs to go to a single PC to make it easy to update when changes occur (on a weekly basis). Has anyone done anything like this? I'm assuming there will have to be some kind of vb or c+ application involved. Thanks, CK

HMI G3 not working using Crimson 2.0
DBOVF posted a topic in Allen Bradley / Rockwell AutomationI know nothing about HMI's or Crimson software. I'm in I.T. and we had to change the third octet in the IP address and gateway on all devices at our warehouse. I extracted the file on one HMI, changed the ethernet info, and clicked send. That HMI that runs a carpet machine works perfectly. I went to the second carpet machine. Extracted the file changed it's ethernet info, clicked send. It came back with all ---- (dash's) instead of zeros, the carpet machine won't work. I kept messing with the file trying different things, and inadvertently saved over the original extracted file!!!!! So I thought I'd extract the file from the working carpet machine and loaded it on the second carpet machine. I get the same issue, all ---- (dash's) on the HMI and you push any of the buttons on the front of the HMI and nothing works. These are Allen Bradley MicroLogix 1500 running Crimson 2.0 HELP I don't know how to resolve this issue. I would have thought both HMI's would have been the same! HMI all dashes.eml HMI all dashes2.eml
MicroLogix 1100 IP Addressing
KeithBurns29 posted a topic in Allen Bradley / Rockwell AutomationI have a micrologix 1100 PLC as well as a weintek HMI all connected through a network switch for them to communicate between each other, however I'm having an issue where the Micrologix Controller will not retain its IP address once I set it through Allen Bradleys BootP tool. I can set it through the tool and then go into RSlogix 500 and communicate with it and all that, but once the controller is turned off the IP address goes back to its factory setting of not showing an IP at all. Any suggestions/ ideas as to what I'm doing wrong?
