  1. I have a "paddle wheel" style flow meter that I am trying to wire to my Micrologix 1400. It is a three wire device and there is a tag on it that says it can run at 6-36VDC. So, naturally, I thought to wire this to one of the HSC inputs of the Micrologix directly. I hooked the ( + ) on the meter to 24V, ( - ) on the meter to common, signal to the oscilloscope, and ground on the scope went to common. I see a small 60Hz sine wave @ like 5mv when the wheel is not turning. When the wheel is turning I get a small square wave but in the same mV range. It is not a nice smooth square wave either its all jumbled up with the 60Hz sine wave.  I hooked this thing up to a transmitter and scoped the signal and ( - ) in parallel with the wheel - I get a nice smooth square wave signal when the wheel turns. It is only at 4.5V though. My questions are? Why does't the paddle wheel give me what I am expecting directly? Also, what is the voltage range on the pulse that a micrologix will see? I am assuming that it will not count a wave with a 4.8V amplitude.... Thanks for your help in advanced! neech

  4. Hey guys, I'm trying to power about 31 armor blocks in a daisy-chain. I'm running my power off a panel to a junction box and then drawing cables to Taps and dropping a cable to each Armorblock. I'm using 1732E-8x8M12DRs and 1732E-IB16M12Rs, which have 4-pin mini male ports for power.  1. Are there 4-pin mini cables (18AWG) Taps so I can power the entire system using 18AWG cables? 2. Is it safe to gave 22AWG micro cables and M12 taps and draw out a 4-pin mini cable drop to my armorblocks? 3. What in your opinion would be the best way to daisy chain power to these modules? Thanks!
  5. We have a contract to refurbish/upgrade a filling/bottling machine. We have the machine but not its control panel or PLC. We've built a new control panel based on the original drawings. We've changed the obsolete 1756-MVI/A serial comms modules to ProSoft MVI56E-MCM modules. These two comms modules are to talk to sixteen (16) Endress & Hauser Promass 63MT08-WOW00A9092B mass flow meters - each module talks to 8 of the 16 meters on separate RS-485 networks. My problem at the moment is that there seems to be no way of knowing the port configuration parameters (i.e. baud rate, data bits, stop bits, parity etc.) without having the original 1756-MVI modules. I should add that these meters are 'blind' with no built-in keypad or display for programming or querying the program. I've approached E&H in the hope that they would have a method of extracting the configuration from the meters but they are saying that the meters are so old that all their expertise and equipment for performing such a task is no longer around. I'm going to attempt to track down the original equipment manufacturer in the hope that they may have kept records. Other than connecting up to a meter and trying multiple combinations of settings in the hope that we hit on the right one, does anyone have any ideas on how we can make progress with this? Also, the meters use what appears to be E&H's proprietory Rackbus protocol. The original 1756-MVI modules could talk to them (presumably!). Any ideas if the new ProSoft modules will be able to?
  6. 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. A separate utility automates the data mapping to your PLC logic.  Features -Serial Master (BASIC required Option); TCP; Slave; Redundancy; More than 5000 accumulative registers; MB CFC (Custom/Private Function Code) Support; Data mapping too – Between PAROCK1 & your PLC logic; Packaged with Rockwell; TCP/IP Interface Module; Volume Discounts; Annual Support Requirements -Rockwell/AB-CLgx processor with v16 or later.  Contact PCI for earlier versions. -If using CPU’s Chan0, you cannot use Chan0 for any other user mode activity.

  7. Hi, I'm using FWRIT to log data and want to know if it's possible to detect power failure to not write to the CF memcard? You can extend the power OFF up to 10ms or use the power off interrupt. Does anyone make experience with that?

I'm a new control engineer who just started working in a power plant and has limited exposure to the troubleshooting of this and i really hope that any of you can assist me. Thank you very much.
  10. I have an EP24DC module that will not supply power to the bus. Swapped the module out and still have the same issue. Any Idea's !
  11. I need to make a setup like the readings in the energy meter should be a GSM then from this GSM the data should be sent to another GSM using Twido PLC.,please help me how to establish this connection. (Energy meter ----+ Twido PLC----+GSM) data from this should go to another similar set up (GSM----+Twido PLC---+Energy Meter) I dont know is this possible or not please help me,,
  12. At work we have been having a slightly increasing number of instances where the Micrologix 1400 that is paired with a Panelview C400 resets values when we cycle the power. Originally we thought the solution was a bad battery in the ML1400. This was the case the first few times that it happened. However, we recently had one doing the same thing and when the program was loaded onto another PLC and HMI combo it had the same issue. So either the battery for both just happen to be bad, or there is something in the program that is forcing the values to automatically reset when the power is cycled. I cannot post the program on here but I can tell you that the tags that are being reset are only used in the PLC program once. There are six total that are being reset and they are the high and low range in an SCP function that is used to scale inputs. I will be testing the program myself in house on a bench setup, but I wanted to get this question out there as soon as possible in case it is not an obvious problem. Has anyone seen this before? Any suggestions? If I come up with an answer I will post it. Thanks.
  13. SIMATIC OP7 RAM failure

    In our SIMATIC OP7 console ram failure message is appering while power on, do anybody know about the problem and its remedy ?
  14. Hi Good Day, I need a suggestion, I have an omron encoder, encoder counter meter (K3NC-NB1A) and communication card RS-232C 25pins (K31-FLK1). My question is, what is the best omron software to read and manipulate the data from the encoder (I have CX-one software but I only use CX-programmer). I want to capture the encoder pulse and convert to velocity, acceleration, deceleration and also energy absorbtion. I have to use mathematical formula such as two times differentiation. I also need to show grapf and display final result that is energy absorbtion reading. Or is it much simple if I use VB / labview / java software? Thank you in advance
  15. I wonder if there is version of Ethernet Remote IO that can be used with 115VAC supply rather then 24VDC? This would save me a power supply which is really needed for this module only.
  16. Micrologix 1400 HSC:0 Looking for a configuration example. Using a gas meter with a contact output representing x pulses per cubic foot of gas. Want to calculate flow rate and totalize.
  17. Dear All, I have a little problem in reading data from Power Meter to Vijeo Citect v6.0 I'm using Schneider PM810MG for Energy reading from Power Meter and for the SCADA I'm using Vijeo Citect v6.0. I can do some simple data reading like current, voltage and the others using variable tags from Vijeo Citect with Data type INT. But i dont know how to read the data for "Real Energy In" since the data range from 0 to 9,999,999,999,999,999. Waiting for all your help soon. Thx. Best Regards, Budiman Chandra
