5.2.1. Profibus-DP Master Control Word

The output word located at addresses 16#0200 (MSB) and 16#0201 (LSB) in the gateway’s output memory constitutes the Profibus-DP master command word. Its structure is described below:

Bits Description

15FB_HS_CONFIRM: Acknowledgement bit of a gateway diagnostic

The Profibus-DP master must compare the value of the FB_HS_CONFIRM bit to the value of the ABC_HS_SEND bit (bit 15 in the gateway’s status word). If these two values are different, this means that the gateway has transmitted a new diagnostic to the Profibus-DP master.

To tell the gateway that it has read a diagnostic, the Profibus-DP master must copy the value of the ABC_HS_SEND bit to the FB_HS_CONFIRM bit. This allows the gateway to issue a new diagnostic.

Summary:

•If ( FB_HS_CONFIRM = ABC_HS_SEND ) Æ The gateway’s status word contains a diagnostic which has already been acknowledged by the Profibus-DP master. So the gateway is free to use this status word to place another diagnostic there.

•Else Æ A new diagnostic is available in the gateway’s status word. The Profibus-DP master can read this diagnostic, but must also copy the value of ABC_HS_SEND to FB_HS_CONFIRM in order to allow the gateway to generate new diagnostics.
