Schneider Electric LUFP7 user manual General Gateway Information, Bytes Name Value

12. Appendix E: Profibus-DP Data and Diagnostics

For the LUFP7 gateway default configuration, the following response is received from the TSX PBY 100 coupler:

Bytes	Name	Value
0-1	Total length	16#0019
2	Number of %IW	16#10
3	Number of %QW	16#10
4-5	%IW offset	16#0000
6-7	%QW offset	16#0000
8	Station Status	16#38
9	Watchdog Factor 1	16#14
10	Watchdog Factor 2	16#01
11	Min TSDR	16#0B
12-13	PNO_Identifier	16#071F

Bytes	Name	Value
14	Group Flags	16#00
15	Address ID (1)	16#02
16	Modular slave	16#01
17	Active slave	16#01
18-19	Settings size	16#0000
20-21	Configuration data size	16#0001
22-23	Size of the data used	16#0000
——	Settings	———————
24	Configuration data	16#7F
——	Data used	———————

(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	Name	Description
0	Configured	16#01 if the slave was configured in accordance with Profibus
1	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	Diagnostic data size	Total size (bytes) of the first diagnostic received
9	Compact diagnostic	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
