Q

Why does my modular EDS file not work?

A

To support modular functionality it is necessary that the “ProxyConnectN (N = 1, 2,…)” entries are defined in EDS section [Connection Manager] of communication Adapter and the corresponding “ProxiedConnectN” entries are  defined in the same section of IO Module.

Examples:

Communication Adapter EDS
[Connection Manager]

   ProxyConnect1 =

      0x04010002,    $ trigger & transport

                  $  0-15  = supported transport classes (class 1)

                  $  16 = cyclic (1 = supported)

                  $  17 = change of state (0 = not supported)

                  $  18 = on demand (0 = not supported)

                  $  19-23 = reserved (must be zero)

                  $  24-27 = exclusive owner

                  $  28-30 = reserved (must be zero)

                  $  31 = client 0 (don't care for classes 0 and 1

      0x44240405, $   point/multicast & priority & realtime format

                  $   0     = O=>T fixed (1 = supported)

                  $   1     = O=>T variable (0 = not supported)

                  $   2     = T=>O fixed (1 = supported)

                  $   3     = T=>O variable (0 = not supported)

                  $  4-7   = reserved (must be zero)

                  $  8-10  = O=>T header (4 byte run/idle)

                  $  11  = reserved (must be zero)

                  $  12-14 = T=>O header

                  $  15  = reserved (must be zero)

                  $  16-19 = O=>T point-to-point

                  $  20-23 = T=>O multicast

                  $  24-27 = O=>T scheduled

                  $  28-31 = T=>O scheduled

      ,ProxyParam7,ProxyAssem3,  $ O=>T default,description

      ,ProxyParam1,Assem5,       $ T=>O default,description

      ,Assem3,                   $ config part 1 (dynamic assemblies)

      ,ProxyAssem5,              $ config part 2 (module configuration)

      "Exclusive Owner",         $ connection name

      "",                        $ Help string

      "01 SLOT_MINUS_ONE 20 04 24 03 2C 01 2C 02";
