  1. Please assist me with the following; regarding the ME96SSHA-MB Power meter data transition with Melsec-Q series PLC; We acquire to read various values on dedicated Modbus storage address registers at the simultaneous into a Melsec-Q series PLC via Modbus (TCP or RTU)  for calculation purposes. Naturally, since the reading of these variables are to provide accurate instantaneous results, it is a requirement that these values are to be read at one scan.   However, as can be seen below, there is a gap in address register range – of which, if all of these are scanned simultaneously, yields an exception error when read. This error is only avoided by scanning these data sets separately – which is not ideal for our application – since accuracy in calculations is imperative.

  3. Omron cp1e power indicator turns off

    The plc runs for a minute and then the power turns off while the supply voltage is ok. I was sure that it is for the power circuit problem inside the plc. As I had a spare power circuit of cp1h and I checked it had same voltages output (5vdc, 24vdc & 0), I replaced it. Now I cannot connect it with my laptop to change to run operating mode. Could anyone help me?
  4. I got denied on a job interview, there might have been a few things but I think not knowing NEC and lack of experience with three phase hurt me. The NEC stuff is for another thread but how do you get experience with three phase? Unless you're in a shop already 3ph can be tricky to find. We talked about it at school in multiple classes but never anything hands on. Yet the descriptions for these entry level jobs all expect you to have a few years in of working with 3ph. It looks like I can make my own three phase from 120VAC with a small VFD. Maybe find some small 3ph motor at the scrap yard, get a new contactor and practice taking measurements/hooking stuff up. I've no problem building a trainer if I get to study up on 3ph and NEC at the same time. Crazy? Any advice?

  7. Daisy chaining power to Armorblocks

    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!
  8. 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. You can use it for non-user mode activities -TCP/IP Interface Modules from Rockwell/AB supported, are: -1756-EN2xx ControlLogix® Ethernet/IP communication modules, firmware revision 5.007 or later -1756-EWEB ControlLogix Ethernet/IP web server module, firmware revision 4.006 or later -1768-EWEB CompactLogix Ethernet/IP web server module, firmware revision 1.002 or later -1769-L30ER, 1769-L30ERM, 1769-L30ER-NSE, 1769-L33ER, 1769-L33ERM, and 1769-L36ERM CompactLogix controllers, firmware revision 20.011 or later -1769-L24ER-QB1B, 1769-L24ER-QBFC1B, 1769-L27ERM-QBFC1B CompactLogix controllers, firmware revision 20.011 or later -1769-L16ER, 1769-L18ER, 1769-L18ERM CompactLogix controllers, firmware revision 20.011 or later Other Related Services/Items -Custom PLC Add-on instructions building -PLC upgrades, troubleshooting, applications -PC Windows, iOS5, Linux, Mobile devices Comm.

  9. 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 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 !
  13. ML1400 and C400 Resetting Values

    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.
  14. 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 ?
  15. 1734-AENT 115VAC

    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. 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
