 DPV1C1_Write_Resp_Progress: This subroutine

DPV1C1_Write_Resp_Progress checks the status of the DPV1 Write

Response message sent to the Master. When the Write response request is

done it will increment a status counter to check how many response requests

have been sent successfully and how many failed. If the Write Response

message was successful the first Rung will copy the Write data to a local

buffer which can be transferred with a CIP response message.

 SR_Copy_Input: The SR_Copy_Input routine on every scan updates the

DpsInputArray structure with the Input Data of the module.

 SR_Copy_Output: The SR_Copy_Output routine on every scan updates the

DpsOutputArray structure with the Output Data of the module.

 SR_Main_Init: Initializes several variables used by different routines.

Numerous user defined data types have been created to make it easier to

address different elements of the Input and Output array of the module. The two

main structures are DpsInputArray and DpsOutputArray.
