  1. We have an SLC 5/05 on our automation network, one of several SLC 5/05 processors on site.  It functions perfectly well and no ethernet messaging issues or SCADA drop outs.  The difficulty I am experiencing with it is when I am required to fault diagnose it takes a very long time to get online to it with our laptop running RSLogix500.  It sometimes takes as long as 10 minutes.  It makes no difference whether I use the Ethernet devices or the EtherNet/IP Driver in RSLinx, it nearly always takes an age which is frustrating in a breakdown situation.  I don't ever experience these long wait times connecting to any other of the SLC 5/05 controllers or any other controllers for that matter.  Once I am connected to the problematic controller I don't experience any issues, it's just the initial time getting online.  I try to leave the laptop permanently connected to it to avoid the long wait time to connect.  When I open RSLogix500, select Comms, Who Active Go Online, Ethernet devices driver, I can see that the problematic 5/05 has Active as its Status whereas the other 5/05 processors have Remote Run as their status.  Please can anyone advise as to any possible program parameters, RSLinx settings or hardware faults I should be looking for?  I have considered it could be a network problem but I'm unsure about this given how the processor performs well in every other regard.

  2. Hello! I am using the Plant PAX AOI L_CPU_24_Up and am having zero luck finding out both independently and from tech support what the 16 bits of the Ref_Out.Identity.Status are. The description says Tag to receive CPU data, device status (bitmapped, see documentation).  I have a techconnect contract, but cant find the correct documentation where this information lives.  Could someone please send me a link or just give me the number of the publication.  I attached a screen shot of tag info I am looking for. Thank you!!!!

    Hello. I can't find any related bits wich would indicate PLC offline / online status. I'm using two PLC's. PLC0 Modbus TCP (Ethernet) PLC1 Modbus RTU (Serial) Please help me to get online status. BR, Andrej. 

  4. b&R 4PP015 Error

    patxi posted a topic in Other PLCs

    I have a 4PP015.0420 panel with the led error that stays between green and red, and it doesn't work.The sequence of the LEDs at power:       Yellow   Red       Green   Red       Green   Green       Green   Green&RedAnd on the display :          Version    1.1          Status     400041000I think there is a Status Register that indicates the errors.How can I see it to know why the PLC is not put in RUN?Thank you in for your help.Sorry for my english
  5. I have IPC and need to detect status of IPC and PLC communication . I need help with the same that how can in detect it ? Is it possible with message instruction ? if it is then how ?
  6. I'm looking for some general information about different types of vibration/temperature sensors. What type, brand, model number, etc. will best fit my application.  Scenario: I want to monitor the vibration and temperature of multiple motors and gearboxes for a large overhead conveyor system. If an oil leak occurs and temperature increases, I want to see a temp. alert via a HMI. If a something mechanical fails, I want to see a vibration alert via a HMI.  I've looked into sensors that stick to the outside housing of the motors or gearboxes via a magnet. My concern is justifying the temperature readings. How accurate would a sensor that reads an "ambient" temperature be (compared to a thermocouple on the motor coil itself or some sort of probe)? Also, would the location of the magnet  on the motor or gearbox drastically affect the temp. or vib. readings? Has anyone had success with a similar setup? If so, what devices did you utilize? Are these systems truly beneficial?  I'm currently considering Banner's wireless products...
  7. Hi, Iam new to schneider electric PLC drive programming and also to canOpen communication. I have an LMC058 PLC and there are three Lexium 32A drives connected via canOpen which inturn controls three servomotors. My question is how to find/ read hardware limit status of the axis in which limit is connected to a digital input pin of the drive. Even though the axis is properly working by configuring the digital input pins we are unable to get the digital input status of the drive. In the drive manual its given that the digital input status can be read from canOpen address 3008:F(hex) we dont know how to read the status during run time in the program . Can any one advise me how to read that address. I tried SDO_read function but its giving me error(canOpen network id Unknown). Thanks in advance.

  8. IFIX Problem

    N_Locus posted a topic in GE

    I have restored a crashed IFIX to a new PC. The restore is ok and installed GE9 driver. With the GE9 power tools, we can observed that data transmits and recieve. The problem is that the screen scada is not updating i.e. no status/feedback, anything is happening. The LAN network TCP/IP was configured i.e. IP, subnet and gateway. Any remedies/advice is most welcome. Please provide a guide on the communication/configuration setup. Thanks

  9. S7-300/400 Status to Wonderware

    huntercc posted a topic in Siemens

    I've been tasked with building several "maintenance" related HMI screens in our Wonderware application for systems running on S7-300 and S7-400 PLCs. I'd like to provide an overview of general PLC status for all PLCs, displaying this type of information: LED StatusStatus of Communication to WonderwareI/O FaultsModule faultsetcFirst on my list was LED Status. I found a Siemens tech document describing how to determine the status of each LED on the processor via PLC programming, but it occurs to me that it's pointless to do so for the Run or Stop LED's - if it's not in the Run state, then the code will not execute, therefor the HMI will always display a healthy status for those two LED's. I'm referring to a Siemens document entitled "Programming Example in Ladder Logic, Getting the Status for the CPU LED Indicators." It would be nice to be able to indicate if a PLC was faulted/stopped. Does anybody out there know of a way to do this with Wonderware? I'm fairly new to Siemens and Wonderware (mostly AB and iFix experience), so detailed answers will be much appreciated!
  10. I have had a GE 90-30 CPU331 in my house for 17 years with no trouble at all. I have a problem that I have never seen before. I was editing the program using LM90. I don't know what I could have done in the program to disable an output. Just 1. All the rest of the points in that group on that card still work. I swapped cards with no difference. All of the elements of the rung are true (highlighted). The output is not on or highlighted. The nickname over the output has ONE letter highlighted. The bit in the reference is "0" and is highlighted or "grayed out" (the cursor is not on it). I searched for coil conflicts. I am using this output contact lots of places but only one output. The logic is working correctly when I use another output or %M. This is an isolated output which needs to be in this group (moving it would be awkward). What does a "grayed out" reference bit mean?
