Communications Parameters The following parameters must be defined in the Siemens Milltronics instrument to establish successful communication. Instructions on how to set these parameters are found in the associated instrument manual. Note: • f denotes factory setting. P751 Baud Rate Sets the baud rate according to the following table 0 = 125 Kbps f 1 = 250 Kbps 2 = 500 Kbps P752 MAC ID Sets the MAC ID (slave address). Valid addresses range from 0 to 63. The default value is 63. Map Element Selection P762 Map Element Selection parameter P762 allows you to select what elements to include in the Input and Output Tables.
By selecting only the data required, you can reduce the amount of data being transferred over the bus. Notes: • P762 should only be modified by an advanced user who wants to limit the amount of data being transferred. For details, see Appendix A – Reducing the amount of data being transferred over the Bus on page 48. • Changes do not take effect until after a power cycle. The charts on page14 give the default values for this parameter. The values differ depending on the category:
• category 1 includes the AiRanger / SITRANS LU series, CraneRanger series, and InterRanger DPS 300 • category 2 includes the EnviroRanger ERS 500, MultiRanger 100/200, and HydroRanger 200 • category 3 includes the Milltronics BW500 and Milltronics SF5 Communicatons Set-up • If the default values are used then the configuration and Data Map (see page 24) in the main body of this manual remain correct. If any of these values is changed, then the Data Map will be shortened and the configuration will change. For details on using P762, see Appendix A – Reducing the amount of data being transferred over the Bus on page 48. 7ML19981BH02 SmartLinx DeviceNet – Instruction Manual Page 13
