  1.   In this first picture is a numerical input with a monitor device D2058. In the whole GOT project this is the only device that saves the information inputed.   Then on que PLC sequence theres an instruction moving that device's value gotten from the GOT to the position module's buffer memory. My doubt comes when there's another device D10022Z9 getting the same value of D2058. In this case the Z9 index is always 0, I checked. In the whole PLC program this is the only part where the D10022Z9 appears, there is no instruction anywhere copying D2058 to D10022Z9 which is how I would think is the way it has the same data always. Am I missing something or how is this possible?  
  2. 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. Drivers -Custom development, Technology Transfer Services  -Other Non-AB communication drivers for serial or TCP  -Full control system integration, training, architecture design This driver can be conviniently used with Visual Studio in development of complete large scale complex HMI/SCADA Systems.

  3. Networking RS Logix 5000

    Hi all, Quick question about adding ENET modules to a plc. If I have a local network of a HMI, PLC and 1 device all on IP 192.168.255.x and I have another device across the plant with an address of 171.27.19.x, can I add that one device to the PLC and it will recognize it? Is there a way to add a device with a totally different IP address to a PLC that is already set up?
  4. Hi All, I have problem about programming serial module Mitsubishi PLC using QJ71C24N. If I unconnect the cable from the module and connect again it show SIO error and the communication become lost or not sending data again. so i have to restart the PLC to make it normal again. Any other solution for solve this error without restart the PLC? Thanks Husanto
  5. Hey guys. New to the forum and new to plcs. I am running into problems quick, fast and in a hurry. Please be patient. I have created a new project. I have added module 1756 ENBT because that is what I will be connected to. On the chassis there is another ether net card which runs to a switch. That switch runs to a 1734 aent card. I have added this module, 1734 aent, as well to my project. Now I must add a 1734 IB8S and a 1734 OB8S. These are not appearing in my list. I proceeded to download and install these add on profiles. After installation, however, I can still not select the I/O modules. Why is that? And how do I fix it? Thanks in advance, HotPie
