7. To see which memory locations are occupied by data from the command you are interested in uncheck the box corresponding to the Preset Multiple Registers command from the TeSys U n 4 node as shown above We can see that the Modbus data transmitted with the query corresponding to this command occupy 2 bytes located from address 0x0208 Memory locations 0x0200 and 0x0201 are reserved see chapter 5 So you will not be able to place any Modbus data in these locations The sizes displayed above the graphics areas of this window In Area 32 bytes and Out Area 32 bytes correspond to the total input and ouput sizes you must configure using the modules presented under SyCon see point 6 You may wish to place the 4 bytes of Modbus data which will be transmitted by the gateway for this command into memory once the changes have been made There are two methods 1 Move all the other output data by 2 bytes which may be a tedious process 2 Change the memory location of the block of data transmitted The first solution is preferable as it avoids leaving any holes in the gateway s memory thus optimising the transfer of all of the data from the Profibus DP master PLC The TSX PBY 100 coupler can exchange up to 242 output words with Profibus DP slaves If communication with a larger number of slaves is required limit the volume of exchanges with the LUFP7 gateway In that case leaving such blanks in the gatew

Frame objects in the ABC LUFP Config Tool user manual entitled AnyBus Communicator User Manual for further information about how to handle Transaction type commands The LUFP7 gateway s default configuration includes two Transaction commands These are aperiodic commands used for reading and writing the value of a Modbus slave parameter necessarily a TeSys U motor starter with the default configuration They are configured solely for the TeSys U n 1 node as the address of the slave is controlled by the Profibus DP master via the first byte of the Data field which corresponds to the Slave Address field in standard Modbus commands This allows the Profibus DP master to send this command to all of the Modbus slaves slave by slave through the first byte of the Data field The remaining fields of the frames used by these two commands are also placed in the same Data field So the Profibus DP master has access to all of the content of the frames in these two commands 6 12 3 3 Using Variable Data Fields in Transactions A Variable Data field is similar to a Data field but has no predefined length Instead a length character i e a number of bytes or an end character is used to indicate the significant length of the data field Each Variable Data field is also protected with a Maximum Data Length that prevents any overflow when there is no end character where one is

215. yte address element see below If used this counter allows the Profibus DP master for example to only consider the response s corresponding data when this counter s value is incremented This element is only used by the gateway if the element Trigger byte is set to Enabled In this case it specifies the address in the gateway s input memory 0x0002 to OxO0F3 of an 8 bit counter managed by the gateway When the gateway receives a response to the associated Modbus command it increments the value of this counter in a unitary manner value value 1 So the Profibus DP master must have access to this counter in the same way as for the periodic input registers from the TeSys U motor starters This mode allows the Profibus DP master to be informed that a new response is available This can be useful for example if it is possible that the data from two consecutive responses may be identical NOTE In the specific case of the gateway s default configuration the Trigger byte element for responses to the Transactions 1 and Transactions 2 personalized commands of the TeSys U n 1 node is set to Enabled Hence the management of responses to read and write commands for parameters is event driven The Trigger byte address elements of the Response elements of these two commands are configured at addresses 0x001E and Ox001F These are the parameter read write response counters C
