  4. Memory Usage

    in UniLogic Software

    Posted

    Hi Marten,

    *Do not open multiple Forum topics/posts when previous one not approved yet.

    Each Forum topic/post require review by administration team before it is approved and everybody will see it (and answer).

    What is a message you see?

    About what part of project?

    Most of memory errors are from retained memory, and from big Data Tables.

  5. Connect PLC to pc with network cable.

    IP Address typo corrected.

    It is recommended to use LAN switch and LAN cable.

    200 ft is ~61 meters. And it is less than maximum LAM segment (100 meters).

    You have to set PLC and PC with static IP inside the same TCP network.

    For example:

    PLC Panel

    IP 192.168.1.2 IP Mask 255.255.255.0 GW 192.168.1.1 (may not exist in your network but should be configured). DNS 192.168.1.1

    PLC CPU

    IP 192.168.1.3 IP Mask 255.255.255.0 GW 192.168.1.1 (may not exist in your network but should be configured).

    PC

    IP 192.168.1.4 IP Mask 255.255.255.0 GW 192.168.1.1 (may not exist in your network but should be configured).

     

    Then you can communicate to PLC 192.168.1.2 IP.

     

  6. ModBus address access limitation

    Until we will update RN/Help, you can use next to check if MODBUS limitation is working or not in your version:

    As soon as you can write into stated SI/SB, MODBUS limitation should work.

    *System registers are write protected, if not used for additional functions.

    At this time only MIs and MBs MODBUS limitation works.

    We added request to wish loist for feature implementation.

  8. ModBus address access limitation

    Hi HexMan,

    This option exist for the enhanced models – Please make sure to use the latest OS:

    1 Set in SI165 the start address of MB the user will be able to access

    2. Set in SI166 the end address of MB the user will be able to access

    3. Set in SI167 the start address of MI the user will be able to access

    4. Set in SI168 the end address of MI the user will be able to access

    5. Set SB305 to activate the MODBUS limit.

     

    For example if you will set the following:

    SI165 = 1000

    SI166 = 1999

    SI167 = 1000

    SI168 = 1999

    SB305 = 1

     

    The MODBUS master will be able to access only to MB1000 – MB1999 and MI1000 – MI1999.

     

    If anyway one tries to access the restricted operands SL46 will increment.

     

    You have to arrange MIs and MBs in sequence.

     

    There is ni separate limitation for read and write.

    B.R.

  10. HMI Freezing

    in UniStream: Hardware

    Posted

    Hi Cam,

    For UniStream. Please check Panel CPU Utilization.

    Then check Action use.

    Check activation all of them in Ladder.

    If Ladder eventually activate actions frequent, than this will make panel responding slow, or not responding.

    Hope this helps to solve problem.

     

  14. Trend Xtime Issue

    in Vision & Samba PLC + HMI Controllers & VisiLogic Software

    Posted

    Hi golzione,

    You are going very deep at user level.

    please send your project to Unitronics Technical Support for review.

    *Add PLC serial number for reference.

    *Is the PLC battery voltage OK? What is a SB 8 status?

    *Does PLC show right time/date? time

    Then we will run it at our desk for simulation and will show result to R&D if we find a problem.

    Until now you are the first who comply for such trend behavior.

    B. R.
