    Hello,
    I try to communicate my PI2 with OTB SCHNEIDER TCP / IP Modbus card.

    OTB config:
    1st module: OTB 1E0DM9LP - V2.xx
    2nd module: OTB TM2AMI4LT - V2.xx

    Config CoDeSys:
    Modbus_TCP_slave_1
    IP: 192.168.1.11
    Unit_ID: 127
    reading code 23:
    read address: 2000
    Writing address: 2100

    Modbus_TCP_slave_2
    IP: 192.168.1.11
    Unit_ID: 1
    code reading 3:
    read address: 2001

    When I want to write an output map (2100) no problem
    The problem is that I can not at all to read the analog channel 2001

    In Advantys,
    the first card is on UNIT_ID: 127 and the next is on UNIT_ID: 1

    Does someone has already tested CoDeSys 3.5 SP6 Patch 1 with material SCHNEIDER OTB?
    What way can we configure OTB cards SCHNEIDER CoDeSys ??????

    Thank you for your help
    Ludo

    Hi,
    I finally found the solution.
    As the cards do not have the same ID_unit , we must separate the reading frames
    See attached image
