WSAENOTSOCK 10038 error on polling with Modnet driver

MaratAbdullin5422

Hi,

we have a problem with connecting Citect with generic modbus device (standalone discrete I / O Module)

through Modnet driver. After Runtime restart we have a error WSAENOTSOCK 10038 error (syslog.IOServer.Cluster_1.IOServer_2 log file).

 After a few minutes connection is restored and system is working fine until next restart.

Connection parameters in .ini file:  MaxPending=2, Block=250, Retry=0, Delay=0, Timeout=1000, PollTime=0, WatchTime=30000.

Modbus Pool with this device works without problem. 

We are using  Version 7.50 Service Pack Patch 13[5].

Log in included file 

citect_logs.txt

Thanks.

  • Hi Marat,
    Can you confirm what OS you are using (if Windows 10, also the version), as well as TCPIP board driver version and Modnet driver version?
    Also upload your citect.ini file for review.
    Thanks

  • In your log, I see the error is from the TCPIP board driver. So, that may be the place to start. The full driver error message is just the Microsoft description for the Winsock error code 10038:

    2019-08-01 14:21:03.125 +05:00 [TRACE] [CORE       ] [0x2d54] [IOServer        ] [(GLOBAL)        ] [DrvDebug()                                        ] [dsp_fmt.cpp                   ] [533 ] Tcpip Driver Error: 10038 (0x2736) Length 214 Socket operation on non-socket. An operation was attempted on something that is not a socket. Either the socket handle parameter did not reference a valid socke t, or for select, a member of an fd_set was not valid.

    That can happen if the software (Citect TCPIP board driver or MODNET driver) closes the Winsock connection, then tries to use that invalid connection. That may be a bug in the Citect driver. I don't know which version of the TCPIP driver is installed, but you may want to install the latest TCPIP driver. It has some recent fixes, but doesn't specify what they all are. I see from the log file you have MODNET v2.09.07.00001. There is an updated MODNET driver available. I don't see a fix for that specific error, but it may be worth trying that also.

  • Hi Olivier,

    OS is Windows 7 Professional Service Pack 1, MODNET v2.09.07.00001. I don't know how to determine a TCPIP board driver version. It's some sort of OS level driver?

    Thanks

  • Hi Eric,

    I installed latest versions of TCPIP (TCPIP_4.00.02) and Modnet(2.09.10.000) drivers. It doesn't  solve a problem. We continue to receive a  

    WSAENOTSOCK 10038 error after SCADA restart during a few minutes.

    Thanks.

  • I do see a pattern in your log file: the error seems to occur every 30 seconds, which corresponds to the WatchTime period. Are you communicating from a single Citect node? Or do you have a redundant setup (2 I/O servers)?

    It might be that the Modbus device is closing the TCP channel while Citect is still trying to communicate. You might be able to tell something more after analyzing the connection with WireShark.

  • Hi,

    I have 2 I/O Servers in single node, first server is working with OPC, second with Modnet. I tried a modification with one  I\O server, it doesn't help to solve a problem.I analyze communication with WireShark.  Modnet periodically trying to access register with 7255 address. Device don't have such address in his address space, so  generate error (illegal data address).

    I can't realize what happening with  device polling in this situation and why Modnet is trying to reach this address.

    Screenshots and Wireshark capture file in sharing link 

  • Without having looked at your attachments yet, I can explain why Modnet tries to read other registers than you have configured.
    Modnet (and all other modbus drivers in Citect too) tries to read modbus registers in blocks to increase performance.
    With most brands of PLCs this is no problem because all addresses exist in PLC memory, but with some brands, especially with some RTU brands, only the configured addresses exist in the device, so you get an illegal data address error.

    To prevent Citect reading addresses in blocks, you should prefix all modbus addresses with the capital letter 'G' in your variable tag definitions. Examples: G7254 or G401190.
