50 6. Configuring the Gateway 6.6. Deleting a Modbus Slave This step allows you, for instance, to free up a locati on on the downstream Modbus network, known as the “Sub- Network” in AbcConf, in order to replace one Mod bus slave with another. In fact the gateway’s default configuration already allows it to communicate with eight TeSys U moto[...]

51 6. Configuring the Gateway However, these operations are not necessa ry when del eting a single slave. Conversely, they become almo st essential when most of the Modbu s slaves are delet ed, because these deletions divid e up the gateway’s memory. Please see chapter 6.11 Adding and Setting Up a Mod bus Command, page 68, which describes all of [...]

52 6. Configuring the Gateway Importing/exporting a Modbus slave configura tion: AbcConf offers the possibility of independently savi ng and loading the configuration of a node on the downstream “Sub-Network”.

81 6. Configuring the Gateway 6.11.3. Adding a Special Modbus Command Apart from the standard Modbus co mmands covered in the previous chapt er, it is possible to create two types of special Modbus commands: Modbus commands using the same template as standard commands and Modbus commands who se nature and frame content can be com pletely changed by[...]

82 6. Configuring the Gateway Constants in Byte, Word or DWord format allow you to relieve the Profibus-DP master by placing the values of these constants in Modbus qu ery frames (constants in “Query” elements) or by com paring them to the values located in the Modbus respon ses (constants in “Respo nse” element s). These comparisons are us[...]
