  1. HI All,  I have an issue with my SCU32 communication.  Back ground Two SCU32s  (top and bottom side) connected via a 1100M datacable  using port1 ( 9600bps,  8-2-E, start code FF, end code FE, Tx save to d1000-d1200 , Rx save to d2000-d2200). PORT2 of bottom SCU32 is connected to a compass( 2 wire, 8-1-N, 19200 bps, serial gateway MODBUS ). Refer to photo Issue  Without compass, the receiving data at top is very stable and is didn't see any fluctuation. But if is compass is connected at bottom side port2, there is a fluctuation at the top side RX data(specifically d2000-d2005 ) .  I checked the data a bottom side TX (d1000-d1200) and it is stable. Only after sending the data and Receiving at Top side, then only the starting words fluctuate. I am not sure sure what is wrong, I am using logical ports for the DTXDU/DRXDU and compass.   Appreciate all your feedback and suggestions.  
  2. 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. 
  3. b&R 4PP015 Error

    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
  4. 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 ?
  5. Communication error

    Hey Guys,    This is my first time on a forum like this! but i need a hand with something if someone could point me in the right direction.   I have a Powerflex 40 drive communicating over Ethernet/IP to a switch, That drive has four Powerflex 4's connected to it thru DSI connection. They seemed to be wired correctly and seem to be sound connections but when someone on the production hits an E-Stop it removes power from this bank of drives. (Which is standard here) . However, when they power back up i get an F081 Error (Comms lost) on the master drive and one slave. Also, the port light on the 20-comm-e(Powerflex 40) is faintly flashing about every 5 seconds and is the only light on. In this state, none of them communicate. However, when i unplug the DSI cable, the 20-comm-e powers back up to normal operation. I then plug the DSI back in and everything works fine.  Should i start replacing parts or is there some parameters/other wiring i could check?   Thanks guys.
  6. Lets say i have a PLC, with a name PLC1 with IP/Subnet of I have to communicate this PLC1 with 2 other PLC's, PLC2 and PLC3 PLC2 with IP/Subnet of PLC3 with IP/Subnet of I imagine that, all these three are in different subnets, and so there should be no communication at all, but when i tested it, PLC1 to talking to/from PLC2 and not PLC3.  anyone know the answer to this ? How does it talk to PLC2 with different subnet, but not PLC3 which is in different subnet as well. 
  7. 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...
  8. 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.
  9. PAROCK1 for HMI/SCADA View File Now a software solution is available for your Modbus (MB) needs in Rockwell/Allen-Bradley Control Logix or Compact Logix (Clgx) family processors, instead of a traditional 3rd party hardware like Prosoft MVI-56, Molex SST-SR4-CLX-RLL etc.  It is an Add-on instruction (AOI) for PLC/PAC firmware v16 or later, (other solutions are available for pre v16 systems).  For hardware interface, use PLC’s channel 0 (serial) or TCP/IP Interface module(s) to have as many MB TCP/IP devices or serial devices.  (Some limits apply based on system configurations, Comm. settings depending on HW used.) Connect any MB Client/Master or Server/Slave device(s) to your CLgx PLC, including flow computers, analyzers, VFDs, Power Monitors, Level gauges, Smart I/O, etc.  All the MB public/native function codes are supported.  32-Bit integers/floats as single entity are supported with byte and word level swapping.

  10. S7-300/400 Status to Wonderware

    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!
  11. 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?
