Dear all, the chapter "Appendix 5 Special Register (SD) for Remote I/O Module List" in the "Reference Manual MELSECNET/H Modules SH(NA)-080124-C" describes the function of the special registers "SD". For me, two registers SD0 (Diagnostic error) and SD50 (Error reset) are interesting. If I'm connected to the CPU and I have an error on the main base, the ERR LED is ON. I can clear the ERR LED with the following function: Host Station: Copy the value from SD0 to SD50 and turn on and off SM50. (Standby Station: Copy the value from SD1610 to SD1649 and turn on and off SM1649.) If I'm connected to the remote I/O module and the ERR LED on the QJ72LP25GE module is ON. I can clear the ERR LED with the following function: Remote Station: Copy the value from SD0 to SD50 and turn on and off SM50. But, if I'm connected to the CPU, and I have an error on the remote I/O base, the ERR. LED on the QJ72LP25GE module is ON. I can not clear the error on the QJ72LP25GE module. How can I clear the ERR LED on the QJ72LP25GE module without connecting to the remote I/O module or pushing the reset button, just with the SD0 and SD50? In the "refresh parameter"-settings and the "network range assignment"-settings I can not configure the settings for the "SD data transfer" on the MelsecNet. How can I do this without additional logic, or is this not possible? Software: GX IEC Developer 7.01 Main base: System A / System B CPU Type: Q25PRHCPU Ethernet: QJ71E71-100 MelsecNet: QJ71LP21GE Remote I/O base: Backplane: Q35B-E MelsecNet: QJ72LP25GE DI module: QX81 DO module: QY81P AI module: 2x Q68ADI AO module: Q68DAI

Thanks waynes, it works now, i had the wrong optical cables.

Hi, how can i configure a remote i/o system? i am using redundant system Q: Main base: System A CPU Type: Q25PRHCPU Ethernet: QJ71E71-100 MelsecNet: QJ71LP21GE System B CPU Type: Q25PRHCPU Ethernet: QJ71E71-100 MelsecNet: QJ71LP21GE Remote I/O base: Backplane: Q35B-E MelsecNet: QJ72LP25GE DI module: QX81 DO module: QY81P AI module: 2x Q68ADI AO module: Q68DAI

at the moment i have mcafee 8.0 installation was done by the installation wizard. noo special settings.

I have MCAffe too, but i don't have any problems.

dear all, I developed my system with following configuration: 2x main base with Q4AR, connected with melsecnet AJ71QLP21 optical cable. ethernet module on the two extension bases for communication with the mx opc server via udp/ip. the communication works fine, but sometimes the following error codes arise on the ethernet module. outline of the mitsubishi user's manual: 1. Error code: C082h Error description: exchange processing ended error in the following exchange: - exchange with GPPW (UDP/IP) - MelsecNet/10(H) relay Error processing: - check to see if the relay station/partner stations are operating correctly. (no corrective action is needed for error when the exchange is being continued) - confirm that there is no errors in the cable connections between the local station and partner stations. - if some load is applied to the line, reduce the load. 2. Error code: C047h Error description: ICMP error packet is received Error processing: - check if the partner remote node is operating - check if the connection cable is loose - check if there is a problem with the connection to the transceiver and the terminator connection does anybody knows, where the problem is? Ps.: please forgive me, english is not my first language.
