(1)This value corresponds to the gateway address on the Profibus-DP network, and its value depends on the position of the two coding wheels described in chapter 2.7.1 Encoding the Gateway Address, page 22.

N.B. depending on the network configuration and status, the resulting data are likely not to be strictly identical to the ones presented above.

12.3. General Gateway Information

Another command, also sent to a Profibus-DP master, makes it possible to obtain less detailed information than a slave's configuration data, and the values of statistic counters related to the exchanges between the queried master and the slave.

If you wish to review the general information regarding a Profibus-DP slave, you may use the SEND_REQ function in an application developed using PL7 PRO. Then, you must use the 16#0031 command code and specifically request that the information for the slave concerned be read (see Implementation Manual of the TSX PBY 100 coupler).

The table below describes the structure and content of the response issued by the TSX PBY 100 coupler to a read command of the LUFP7 gateway general information:

Bytes

Operating

16#01 if the slave has been set up and operates properly

2-3

Number of %IW

Total size (words) of the input data in the %IW area

4-5

Number of %QW

Total size (words) of the output data in the %QW area

6

Input data size

Total size (bytes) of the input data on Profibus

7

Output data size

Total size (bytes) of the output data on Profibus

8

Compact diagnostic data for that slave

10

Diagnostic counter

Total number of diagnostic messages received from that slave

11

Exchange counter

Number of exchanges between the master and this defective slave

12

Unavailability counter

Number of times this slave is present but unavailable

13

Invalid response counter

Number of invalid responses for this slave
