M580 Explicit Messaging with Simocode EIP

[Anonymous user]

HI Community,

I am trying to do Ethernet/IP Explicit Messaging using Data_Exch Block to read Acyclic Data from Siemens Simocode ProV EIP.

First the Structure of Send_Req Pin is not Clear, what are Class Segments, Instance Segments and Attribute Segments. I have made Array of INT type and given Request size & Service Code INT[0] , Class INT[1], Instance INT[2] and Attribute in INT[3]. 

Addressing is done using ADDMX block.

Plus for Management Tag[3], setting length as 8 bytes. Management Activity Bit 0.0 is not toggling but the activity counter in Byte 1 is continously changing. there's no error code in Management INT[1] probably because Activity Bit is not toggling.

RECP is Array of INT Type, First INT element is Showing code 16#048E.

Above application is Get_attribute_Single but will need to do Get_Attribute_All, Get_attribute_Single and Set_Attribute_Single as well.

I have used this device with Rockwell Clx controller and did Explicit messaging there. Need to do the same for M580 too. Please consider me a relative Novice in M580 and respond appropriately as soon as possible.
