  1. Hi all, I am working on a safety PLC conversion project, for which I need to identify the input word address configured on a PSS AI IP card. The manual from the official website shows the address configuration via a DOS tool. I do have PSS SW PG WIN 4.9, but the project file has been created with PSS WinPro 2.3. Within this software there is only the option to configure how the input channel behaves, not which input word is used (see attached screen grab). Anyone with a distant memory if the addresses can be set with PSS WinPro?  
  2. View File NJ/NX Get IP Address A Library containing a function Block that can be run on any Omron NJ or NX PLC. The Function Block will retrieve the host PLC's IP address, Subnet Mask, Gateway, and MAC Address. The Port Details are presented through 2 structures , 1 per-port. In the event the PLC only has one port the structure for Port 2 will be blank. Submitter photovoltaic Submitted 12/12/22 Category PLC Sample Code

    A Library containing a function Block that can be run on any Omron NJ or NX PLC. The Function Block will retrieve the host PLC's IP address, Subnet Mask, Gateway, and MAC Address. The Port Details are displayed through 2 structures , 1 per-port. In the event you only have 1 Ethernet port then the structure for the 2nd port will contain all 0s. Data Format: IP Address - USINT[4] Subnet - USINT[4] Gateway - USINT[4] MAC - BYTE[6]  (hex value) Access the retrieved details by the typical parent-child tag structure. ex. Port_1_Detals.IP_Address[0] will get the first octet of Port 1's IP. Tested on: NX1P2, NX102, NX502, NX7, and NJ301 IMPORTANT: This Function Block should not be run immediately after startup. Allow the PLC a few seconds to establish a connection with the Ethernet network.
  4. Is there an efficient tool to manage and validate CX-Programmer addressing. Requirements: - Highlight Duplicate Address allocation - Compact/Defrag address range to avoid wasting memory space. Note: - Any FINS addressing will have to be reconfigured - This approach assumes symbol use rather than direct addressing in the logic.
  5. It will de nice to have an option for getting a cross-reference report for the AT address used on programs , as is now its easy to make mistakes double setting the same AT address on a program , specially this days that supplies of NA screens are not always availiable and using memory address is necessary for NB screens and SCADA communication and is difficult to keep track of the used address on a program , some times in global or in internals, right now its easy to make a mistake and use the same address twice , and this wont be detected on the compiling
  6. Hi friends, The scene is like this... I have some 200 energy meters whose readings are continuously logged at 15-min intervals into a logging table. The meter does not have any other value logged. Let's consider these readings as analog tags. However these tag values are continuously increasing to ever larger numbers. Thus we have a problem for display on trends. Customer now requires that the Citect shows usage trends for any meter for a specified period of the past. That is to say, the meter that he wishes to observe is selected - along with a period typically between 2 dates (perhaps also with a sampling period) - and the trend must appear. So in other words, given a single trend object, how do you make values appear for any selected tag on this trend. Perhaps this can be overcome by some genie/super-genie mechanism. My approach to this is...For the selected meter, I use SQL to query the 15 minute logged values (also taking into account the required sampling period) taking the reading on starting date as initial. All values thereafter are subtracted -within the SQL query- and the result of this query is kept in a 2 dimensional array(x for time, Y for value) or a new database table so that the trend displays values starting with zero. This much I can do with Cicode. After this, I need a method to display the values so obtained in a trend object. Essentially this is the same as feeding a trend object with a set of X & Y values that I have in the form of an array or in a database table. I shall greatly appreciate any help to meet the above objective. Thanks for looking in. With best wishes.
  7. Hi I'm trying to set up Modbus RTU communication between FX3U PLC and a weigh module. I would use the ADPRW command using 0X03 to read the 16 bit Holding Register but in the weigh module the Data Address/Holding Register of the value I want to get is 400047 - 400048. How to translate the value in 16 bit?   Thanks, Fabio
  8. Need help in table scrolling

    Hi all, We have a DOP 107CV HMI we interface this HMI with microcontroller through RS485 Modbus protocol. I'm new to HMI and PLC's although we are successful in interfacing HMI with Controller(Communication Established successfully) We made a table in HMI and allotted some registers to Modbus address and data is transferred from controller to HMI up to this we are good in communicating Since the table created is static and we cannot scroll down from that table so, to overcome this problem we found History buffer and made PLC trigger and allotted address. In that History Buffer we created 7 rows and the data is sample whenever we triggered the PLC in that case scrolling is working fine, but the problem we are facing is whenever we update 3 rows out of 7 and triggered the PLC only 3 samples are updated in first column and in the next step we updated the other 4 rows and triggered the PLC the data is sampled on next column but we required it to be sample on first column instead of second.  
  9. CS1D I/O Table

    Hi Dears, My project configuration is according to below picture in CX-Programmer i define I/O Table, but i do'nt know how to fill main rack modules like CPU,SCU,Ethernet, . . .  also in expansion racks we have slot 0~9 and in my rack first slot is I/O Interface, and second slot is empty. my I/O table Configuration is ok? can anybody check it? I want to fill I/O table manually and not automatic with upload from PLC.   Best Regards
  10. I am trying to get produced and consumed tags set up between 2 1756 racks with different ip's. The 1st rack has an ip address 172.28.6.3. The 2nd rack has an ip address of 10.81.105.8. Would this be as simple as adding an EN2T card to one of the racks and setting the ip of one onto the same network? Or is there a better way to do this?
  11. CCLink

    Hi guys, I've just completed pre-commissioning on a Mitsubishi project which uses CCLink. My remit was to get the CCLink network up and running which I eventually did but not without issues. Basically, my problem was to do with the number of bits and registers consumed by a station. I read in a manual that each station consumes 32 bits and 4 registers for read and 32 bits and 4 registers for write. On my network I had 3 ST1H-BT modules occupying 2 stations each and 3 non Mitsubishi devices occupying 4 stations apiece. My RWr address starts at W300 and RWw at W500. Like I said everything matched up and I/O checks completed successfully. My question is, and I've trawled through the manuals looking for an answer, how is the number of points calculate? For example my non-Mitsubishi devices they occupy 4 stations, Expanded Cyclic Setting is Octuple and the number of points is 896. How is the 896 calculated? Thanks in advance
  12. Hi everyone My system consists of 2 main stations with 2 CPU Q06UDEH and connected together by QJ71GP21S-SX module but I don't know how to link the address between these 2 CPU together? so can anyone help me? Thanks so much   
  13. We have an iQ-r R08cpu that will not display some labels or addresses.  The PLC and the machine it controls run as expected.  However, when we read from the PLC, some of the labels and addresses are not shown.  Although it runs as expected, we are hesitant to make any changes or write to the PLC. There is a screenshot attached.  Any advice or solutions for this?
  14. Hi folks, I'm trying to communicate with an old CompactLogix L35E via Ethernet. I have already establish communication via DF1 Serial port and was able to go online but I Do not know the IP address to communicate via Ethernet. Can someone please tell me how I could determine the IP Address or create a new one ? This Controller was remove from a working machine. Any help will be highly appreciated. Thanks, Anthony.  
  15. hallo all, I want to ask if I click "read PLC Data" the "points" will appear, I use the QY18A output module that uses 8 points but there is no choice, the smallest is only 16 points.  so I can't put 148 in the "start XY" column ... will it affect the I / O address in the program?
  16. Lets say i have a PLC, with a name PLC1 with IP/Subnet of 10.125.34.243/255.255.255.0 I have to communicate this PLC1 with 2 other PLC's, PLC2 and PLC3 PLC2 with IP/Subnet of 10.125.34.10/255.255.0.0 PLC3 with IP/Subnet of 10.125.46.10/255.255.0.0 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. 
  17. 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.

  20. Double address - Alarm

    Hello, I would like to see your logical opinion about this situation and in which part of system where I need to find solution - software or in the physical field. Subject: Twelve old system based on Mitsubishi PLC AnS series, Profibus Here is pneumatic transport, with 5 lines, each line have a shredder and discharge valve. A few months ago, when line 1 works , display shows line 2 and vice versa, it was first problem, but the system was still working. From the last week system doesn't work. On the display appear line 3 in works, but system can not started. Alarm shows Double address (perhaps two valves have some address), Alarm still appear after reset and even all lines are turned off. What is your opinion where to find proble (PLC, I/O moduls, cables,...)  
  21. Hello.   I'm trying to communicate between two PLC's  using FINS function block _CPU011:ReceiveData.   PLC1: IP 192.168.1.50 (MASTER)   PLC2:IP 192.168.1.51 (SLAVE)   If I don't use »IP Address Table« everything works using NODE number &51.       The problem is that on the real project these two PLC's will be on different subnet.   For example:   PLC1: IP 192.168.1.50   PLC2: IP 192.168.2.50   So I will have to use »IP Address Table« to achieve communication between these two PLC's.   I tried to sett IP Address Table on MASTER: Node 1=192.168.2.50   But If I try to communicate I see that packet is sended to network but I've got error #1005.   Do I have to sett the SLAVE IP Address Table?   Hoe to do this?   What are the right settings for MASTER and SLAVE IP Address Table?     I'm attaching pictures of CARD settings.  I don't want to use CX-Integrator because I would like to make project to UPLOAD and forget.       Thanks.  
  22. Dear all, I'm first time using M580 (hotstandby). Now finish the configuration, but the problem is how to write the address for Digital Input, Digital Output, Analog Input, and RTD module in elementary variable ? I try to put name DDI_1 and the address is same with M340 topology like %I2.1.0.1.1  and for digital input but got message after build : {Elementary Variables}    :     The instance is located on an address that isn't configured. :     DDI_1 Thank you for your advice regards  
  23. Dear all Please identify me i am having one Issue in my PLC.When I changed the IP of my plc then suddenly its showing error ERH its mean IP address wrong but  My CPU setting is same like previous means unit no=0, x16^0=0 ,Node=x16^0=1  and IP is 192.168.0.15 Mask add.255.255.255.0. but when I, transfer to PLC (in Program Mode) its not transferred(Failed to Transfer) please rectify me where I am doing wrong.
